i have created a fresh new React native application, however if i try to run the app using npx react-native run-android i'm getting the error.
npm ERR! code ENOLOCAL
npm ERR! Could not install from "PC\AppData\Roaming\npm-cache\_npx\15180" as it does not contain a package.json file.
npm ERR! A complete log of this run can be found in:

Install for [ 'react-native#latest' ] failed with code 1
Why we receive this error?.
Its really annoying by seeing the people are giving -ve vote for my question without proper reason.
it may be useful for someone who is really facing the issue
follow below steps
you can change "npm-cache" folder to anothor path,
using command :
"npm config set cache C:\tmp\nodejs\npm-cache --global"
This will resolve the issue.
More info https://github.com/zkat/npx/issues/146
I did a lot to solve this almost spend 2 hr in mine case i was not allow to delete package-lock.json
uninstall node
brew uninstall node;
# or `brew uninstall --force node` which removes all versions
brew cleanup;
rm -f /usr/local/bin/npm /usr/local/lib/dtrace/node.d;
rm -rf ~/.npm;
install again
brew install node;
which node # => /usr/local/bin/node
export NODE_PATH='/usr/local/lib/node_modules' # <--- add this ~/.bashrc
Getting error "Config.h file not found, lexical or preprocessor error."
I am running app in the device from the xcode project.
I have google and found many solutions but haven't worked, I tried this
https://github.com/facebook/react-native/issues/14382
And when I try to run in the iOS simulator getting this error
https://github.com/facebook/react-native/issues/10401
Tried to follow the above url but didn't work.
Please let me know how to solve the issue.
Thanks
try it
Open Terminal, go to your project’s root folder and do:
cd node_modules/react-native/third-party/glog-0.3.4/
Run the configure script:
./configure
Open Xcode and try to run your app.
Xcode 10
"react-native": "0.57.5"
cd ./node_modules/react-native && scripts/ios-install-third-party.sh && cd third-party && cd $(ls | grep 'glog' | awk '{print $1}') && ./configure
I faced the same issue and it's fixed by these commands:-
yarn
rm -rf node_modules/
yarn cache clean
yarn install
npm
rm -rf node_modules/
npm cache clean
npm i
For me:
# rm -rf node_modules
# npm cache verify (Because I'm using npm version 5.0.3)
# npm install
Xcode Clean
Xcode Run
If that doesn't work,
In the Terminal, navigate to the react-native/third-party/glog folder inside node_modules
(for me, this was cd node_modules/react-native/third-party/glog-0.3.4)
Once actively in this folder,
#run ../../scripts/ios-configure-glog.sh
Glog is configured and the required config.h header file is created for Xcode to find
Just go on the config.h file, click on the right panel and add the file to the app target by checking the right case. Clean and compile again.
Remove the third-party folder in your node_modules/react-native folder.
Followed the setup steps from official site,I am not able to find react-natve command refer below console commands and its output:
Bhushans-MBP:node_modules bhushanraut$ npm install -g react-native-cli
/Users/bhushanraut/.npm-packages/bin/react-native -> /Users/bhushanraut/.npm-packages/lib/node_modules/react-native-cli/index.js
/Users/bhushanraut/.npm-packages/lib
└── react-native-cli#1.2.0
Bhushans-MBP:node_modules bhushanraut$ react-native init AwesomeProject
-bash: react-native: command not found
Please help me to resolve this.Thanks in advance.
The issue is /Users/bhushanraut/.npm-packages/bin/ directory is not added to global PATH variable.
You need add that to PATH variable.
Execute the below command in terminal
vi ~/.bash_profile
This will open the file in vi editor. Append the following line in that file.
export PATH=$PATH:'/Users/bhushanraut/.npm-packages/bin/'
Then save and close the file.
Execute the following command
source ~/.bash_profile
Now try executing react-native init AwesomeProject command. This should solve the problem.
The below steps may be useful for react-native installation if you encounter any problem
Steps followed from the below URL
https://shift.infinite.red/getting-started-with-react-native-development-on-windows-90d85a72ae65
npm install -g react-native-cli
react-native init AwesomeProject
cd AwesomeProject/
((if not exist "%USERPROFILE%/.gradle" mkdir "%USERPROFILE%/.gradle") && (echo org.gradle.daemon=true >> "%USERPROFILE%/.gradle/gradle.properties"))
react-native run-android
There was error unable to configure the gradle from #react-native-community/CLI-Platform-android
Hence navigate to AwesomeProject/node_modules, run the below command
npm i #react-native-community/cli-platform-android
Finally build is executed successfully without any error
react-native run-android
In another command prompt start the emulator
C:\Users\tapzu\AppData\Local\Android\Sdk\emulator>emulator -list-avds
Nexus_6P_API_28
C:\Users\tapzu\AppData\Local\Android\Sdk\emulator>emulator -avd Nexus_6P_API_28
I've installed react-native-cli globally:
npm install -g react-native-cli
Then run:
react-native init AwesomeProject
cd AwesomeProject
I got the following structure:
-- AwesomeProject
---- node_modules
------ react-native
When I run react-native run-android I get an error:
Command run-android unrecognized. Did you mean to run this inside a react-native project?
When I run react-native start I get the same.
react-native -v
prints:
react-native-cli: 0.2.0
react-native: n/a - not inside a React Native project directory
What I'm doing wrong?
the answer is easy nad it is not because of any bug at all.
make sure you are in correct directory
if in current directory there is not any react native app ,it gives you this error
What caused this for me was running npm install --save [package] when actually the system has previously been using yarn instead of npm.
To solve this I just deleted the node_modules folder and ran: yarn install and after that react-native run-ios (or android) works fine.
(This is a duplicate of React Native: Command `run-ios` unrecognized)
I just ran "yarn" with no arguments and it fixed it.
Please try this command:
npm install --save react-native
The problem was that I terminated init command because it looked like hanged without errors (even 24 hours later). To fix this I updated nodejs and npm to newer versions. Once I have done it react-native init was executed properly and there is no more problem with react-native run-android.
react-native run-android is unrecognized
Make sure that you have installed npm or use
in your project directory
npm install
you have to update your npm.
To do that
npm install npm#latest -g
try "yarn install".
It will install the missing files in node_modules
It worked for me
This can be caused by a couple of issues.
!!! Before trying each solution remember to open a new terminal since you might have old paths sources from your .bashrc file. !!!
You did not install the contents of the project. In order to solve this you have to install the node_modules by typing:
npm install or yarn install
You are coming back to a previously installed project after doing some funny things with your react-native installation and global configurations. (Upgrading the library, upgrading node doing something with globally installed node_modules).
You should clean all your caches and project modules
Here you can find a command to do all these things in one line (remember to replace npm with yarn accordingly):
https://gist.github.com/jarretmoses/c2e4786fd342b3444f3bc6beff32098d
Your global installation of react-native or react-native-cli is broken. In this case simply reinstall your libraries globally.
npm: npm install -g react-native && npm install -g #react-native-community/cli
yarn: yarn global add react-native && yarn global add #react-native-community/cli
I think the command you are looking for is react-native run-android.
cd into your project and run this command where all you js files are present and not in the android folder.
It will run a package manager, do not close that. Also you need to have an emulator or a device connected to your computer with usb debugging enabled.
Hope the answer helped
npx react-native run-android
Use of npx will pick local npm node_modules directory
Do npm install then run react-native run-android
Make sure you go into the directory having package.json
If you have deleted nodemodules try "npm install".
And don't forget the "init" in "react-native init MyApp". "init"
initializes the package.json.
Step 01 : Make sure that you are in right directory
Step 02 : npm install run this command
Step 03 : npm audit fix run this to fix issues
Try deleting node_modules folder and then run the commands again
You can solve this by yarn or npx:
yarn react-native run-android
npx react-native run-android
Everything has already tried like me? Then try again once "Yarn install after deleting node_modules". It worked for me.
I did everything correct while setting up, but was unable to run the android code. Just make sure while running the command react-native run-android that, you are inside the AwesomeProject folder created by the react-native init AwesomeProject command.
The folder by default for my PC was under C:\Windows\system32\AwesomeProject in Windows.
Hope it helped for the first timers :)
You need to update the project with the latest version of react-native. Just run this command.
npm install --save react-native#latest
If you guys have latest react native version and facing this error
"UNRECOGNIZED COMMAND run-android".
then run follow these steps it will definitely help you.
Step: 1 -> create a new file "react-native.config.js" in the project root directory.
Step : 2 -> Inside "package.json" you have "assets" array inside "rnpm" object cut these assets from this and paste in your "react-native.config.js".
i-e:
module.exports = {
assets: ['./assets/fonts'],
}
Step : 3 -> Remove "rnpm" object from "package.json".
Step : 4 -> Replace your "scripts" with below mentioned "scripts" inside "package.json"
"scripts": {
"start": "node node_modules/react-native/local-cli/cli.js start",
"test": "jest",
"android": "react-native run-android",
"ios": "react-native run-ios",
"lint": "eslint .",
"android:prod": "npx react-native run-android --variant=release",
"ios:prod": "react-native run-ios --configuration Release"
}
That's it
Happy Hacking..............
Uninstall react-native from global
$ npm uninstall -g react-native
Then
Install react-native to global
$ npm install -g react-native-cli
That worked for me
react-native run-android
start [options] starts the webserver
run-ios [options] builds your app and starts it on iOS simulator
run-android [options] builds your app and starts it on a connected Android emulator or device
new-library [options] generates a native library bridge
bundle [options] builds the javascript bundle for offline use
unbundle [options] builds javascript as "unbundle" for offline use
eject [options] Re-create the iOS and Android folders and native code
link [options] [packageName] links all native dependencies (updates native build files)
unlink [options] <packageName> unlink native dependency
install [options] <packageName> install and link native dependencies
uninstall [options] <packageName> uninstall and unlink native dependencies
upgrade [options] upgrade your app's template files to the latest version; run this after updating the react-native version in your package.json and running npm install
log-android [options] starts adb logcat
log-ios [options] starts iOS device syslog tail
dependencies [options] lists dependencies
info [options] Get relevant version info about OS, toolchain and libraries
They have made some unnoticeable changes. For instance run-android(now) run android(before).
Try to delete "package-lock.json" and re-run "npm install", then try your command, It should work
I got this error because I had parenthesis in the path "(" and ")". Possibly this error is thrown for other special characters as well.
Ensure you run the command in the projects' terminal, preferably the Android IDE. Run the adb devices to know your active devices as well
If your package.json file is containing any comment then this error is comes. So remove all comments from package.json and then run command it will work.
Also try to run command npm install --save then it will log if other error there. If any others error also there, then first fix it and then run command it will work.
In Android Studio click in Tools -> SDK Manager -> in System Settings click in Android SDK -> choose tab SDK Tools, then enable Android SDK command line tools (lasted).
It work for me!
Open your React Native Project Root Directory and locate android -> app -> build -> intermediates -> signing_config -> debug -> out -> signing-config.json
Delete signing-config.json file
And rebuild your application.
react-native run-android
First thing you need to delete node_mouldes and package.lock.json and do yarn install after that if you're using Windows OS you need to use PowerShell not git bash and write this command "react-native run-android"
Install npm again to latest
react-native init project_name
cd project_name
open android studio the same android folder inside your project_name
react_native run_android
will work now
for the last time your project was working fine and now you got this error suddenly and you have Node modules already installed then just trynpm install --save react-native
this work for me
I am getting -bash: react-native: command not found error while creating a react-native project.
Below are the additional info
1. brew --version
homebrew 0.9.9
2 brew info watchman
watchman `enter code here`stable 4.50
/usr/local/Cellar/watchman/4.4.0
3. brew info flow
stable 0.24.1
/usr/local/Cellar/flow/0.24.1
4. brew info node
stable 6.1.0
/usr/local/Cellar/node/6.1.0
5. npm -version
3.8.6
6. echo $PATH
/Users/Ashok/.rbenv/shims:/Users/Ashok/.rbenv/shims:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin
I tried the suggested steps from this link but I am still getting the same error.
I don't have any "npm" directory which they have specified in the solution
Ashoks-MacBook-Pro:share Ashok$ ls
aclocal doc info ruby-build zsh
autoconf emacs man systemtap
But I found npm file exists in the below location.
/usr/local/Cellar/node/6.1.0/etc/bash_completion.d
I uninstalled react-native and installed it again but I am still facing the same issue.
After adding right path to the PATH variable issue is resolved.
Below are the steps to find the right path.
1. Enter: npm install -g react-native-cli
output: /usr/local/Cellar/node/6.1.0/libexec/npm/bin/react-native ->/usr/local/Cellar/node/6.1.0/libexec/npm/lib/node_modules/react-native-cli/index.js/usr/local/Cellar/node/6.1.0/libexec/npm/lib
└── react-native-cli#0.2.0
from above output you can clearly see the path: /usr/local/Cellar/node/6.1.0/libexec/npm/bin/react-native
export PATH="/usr/local/Cellar/node/6.1.0/libexec/npm/bin:$PATH"
react-native init appName
cd appName
react-native run-ios
if you getting xcrun: error: unable to find utility "simctl" at this stage you can reslove using below steps
XCode -> Preferences -> Locations -> Command Line Tools -> Choose Xcode 7.2.1
You can find original solution from xcrun unable to find simctl
Thanks to #fbozo
That's It!!!
run this code
npm i -g react-native-cli
close your cmd and open it again
After continually running into this problem, and hitting this answer and not having it work..
Assuming you don't run npm as root/sudo (which you shouldn't do!) your npm modules will be installed in whatever you set your default directory to be.
Assuming you have followed those instructions, and your default directory is ~/.npm-global, then you need to add ~/.npm-global/bin to your path.
This is outlined in those instructions, but for me I added this to .bashrc:
export PATH=$PATH:$HOME/.npm-global/bin
Then restart your shell and it will work.
Try
npx react-native
if doesn't work install globally
npm i -g react-native-cli
If who have error , try it with sudo:
sudo npm install -g react-native-cli
If you're using yarn, you may have to run commands with yarn in front. Example:
yarn react-native info
I ran into this issue by being a bit silly. I use nvm to manage my different versions of node, and installed react-native into a version of node that was not my default. Upon opening a new shell, I lost my command. :) Switching back of course fixed things.
If for some strange reasons, the path to react-native is not in the PATH, you should take note where the react-native executable is installed. Generally, the issue with command not found is because they are not in PATH.
For example, I use nodenv and run npm install -g react-native
/Users/khoa/.nodenv/versions/10.10.0/bin/react-native -> /Users/khoa/.nodenv/versions/10.10.0/lib/node_modules/react-native/local-cli/wrong-react-native.js
So I need to add that to my PATH
export PATH=$HOME/.nodenv/versions/10.10.0/bin:$PATH
You can verify with echo $PATH
Or you can use npx to execute local npm modules, for example
npx react-native run-ios --simulator='iPhone X'
Install react-native globally by using the following command
npm i -g react-native-cli
Had the same issue but half of your approach didn't work for me .
i took the path the way you did :from the output of react-native-cli instal but then manually wrote in ect/pathes with:
sudo nano /etc/paths
at the end i've added the path from output then ctrl x and y to save .
Only this way worked but big thanks for the clue!
Install react-native-cli with npm install -g react-native-cli.
You may need to use sudo like sudo npm install -g react-native-cli
At first run this command on your terminal.
npm i -g react-native-cli
Then create your react-native project by this command.
React-native init Project name
then move to your project directory by cd command.
According to official documentation, the following command worked for me.
npx react-native run-android
Link is here
https://facebook.github.io/react-native/docs/getting-started
I was trying to run by "react-native run-android" command. make sure to have react-native cli installed globally!
In case anyone has this problem, I had a similar problem to qix, but more nuanced.
New shell terminals would default to a different version of node.
I would change my terminal to the node I wanted, but when the bundle script run, it ran in a new shell, and it got the default version which did not have react-native installed.
I used nvm alias default x.x.x so that new shells would inherit the default version I wanted.
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
brew install yarn
brew install node
brew install watchman
brew tap AdoptOpenJDK/openjdk
brew cask install adoptopenjdk8
npm install -g react-native-cli
Dears,
Please try : npm install -g react-native-cli
If you get an error like Cannot find module ‘npmlog’ you can install npm directly using this command. If the above command run successfully then no need to run this command
curl -0 -L https://npmjs.org/install.sh | sudo sh
#For_Ubuntu.
Best regards.
In cmd Administration mode,Run
npm install react-native-cli
This is really weird, on my side (macOS 10.14), i'm pretty sure my node and npm work but i kept getting command not found only for this particular package. I ended up doing the following:
Install react-native-debugger
Make sure you enabled remote JS debugging, docs
Run react-native-debugger
Run your RN app
You can now debug view hierarchy and see console logs in react-native-debugger
I already had react-native and react-native-cli installed and just had to run:
yarn install
I had this issue after ejecting from expo and forgot to delete the node_modules and reinstall by running yarn or npm install.
After I did that then run npx react-native run-android, it worked fine!
try using react-native --help and see what comes up. try curl
react native library recommendation:
If you get an error like Cannot find module 'npmlog', try installing npm directly: curl -0 -L https://npmjs.org/install.sh | sudo sh.
https://facebook.github.io/react-native/docs/getting-started.html
I did an npm update, runned into the same error but after do an npm install and re-build the app worked!
