Unable to resolve module `./Linking/Linking` from `node_modules/expo/build/ExpoLazy.js`

Has anyone experience this error with expo, when running react-native run-android?
error: bundling failed: Error: Unable to resolve module `./Linking/Linking` from `node_modules/expo/build/ExpoLazy.js`:
None of these files exist:
* node_modules/expo/build/Linking/Linking(.native|.android.js|.native.js|.js|.android.json|.native.json|.json|.android.ts|.native.ts|.ts|.android.tsx|.native.tsx|.tsx)

"expo": "^37.0.9",

Just ran into this issue, downgrade to 37.0.8 (no caret) and do an npm i. Looks like they released 37.0.9 yesterday and it has an issue.

What worked for me:
1) In package.json change to "expo": "37.0.8"
2) Delete your node_modules
3) installl packages npm i
4) clean cache in expo expo r -c
Now it started to work again. Couldn't find the last step in previous comments.

This is an Internal bug of react-native. You don't have much of a choice, as user3916570 consider downgrading.

For now, downgrading Expo to 37.0.8 fixed this. To downgrade, in your package.json, change your Expo dependency to:
"expo": "37.0.8",
Then remove your node_modules and reinstall everything:
rm -rf node_modules
npm i

It's not an expo version problem only, you should also check the global expo-cli version and probably node as well.
Run:
$ npm install -g expo-cli --force
$ rm -rf node_modules/
$ rm -rf package-lock.json
# (in my case mac '$ brew upgrade node && npm install -g npm')
$ npm install
$ npm run

React Native error: Cannot find module 'jest-serializer'

any one can help me? i have a problem when i run 'npm start'. this is the
Error Message

Try to run npm install jest-serializer before doing npm start. If that is still not working,
rm -rf node modules
npm install
npm start

Can't install react-native-cli after following tutorial

Before reading and following the tutorial in NPM I installed the react-native-cli globally and it worked just fine
But in the tutorial it asks you to install sinopia
https://www.npmjs.com/package/react-native-cli
Then it gives you these instructions
react-native$ npm set registry http://localhost:4873/
react-native$ npm adduser --registry http://localhost:4873/
# Check that it worked:
react-native$ npm config list
react-native$ npm unpublish --force
react-native$ npm publish
react-native$ cd react-native-cli/
react-native-cli$ npm unpublish --force
react-native-cli$ npm publish
But the unpublish part gave me an error. the same for the 'publish' aprt.
(By the way, publish what?!)
Then it says to uninstall react-native-cli
npm uninstall -g react-native-cli
After that I couldn't reinstall react-native-cli.
It says the package is not available.
npm ERR! 404 no such package available : react-native-cli
npm ERR! 404
npm ERR! 404 'react-native-cli' is not in the npm registry.
What is this?! How can I fix it?
#edit
By the way, I don't understand why, in the Get Started tutorial it doesn't tell us how to install the react-native-cli nor gives us a link. It just states:
The React Native CLI #
Node.js comes with npm, which lets you install the React Native command line interface.
#edit2
I just managed to install react-native-cli by removing the 'registry' entry from npm config, installing it and adding Sinopia again.
I thought Sinopia worked as a proxy. If it is not found in local repository, it looks for it in NPMJS...
I even tried to install other things and I could (wdio, nodemon), I just got an error with react-native-cli.
It seems that something is wrong.

Seems like you on Windows
I don't think you need sinopia.
Tutorials was little improved on master branch of the docs: http://facebook.github.io/react-native/releases/next/docs/getting-started.html
In short:
Install node.js
Install react-native-cli: npm install react-native-cli
Install & setup Android SDK
Create & run project
react-native init AwesomeProject
cd AwesomeProject
react-native start
react-native run-android

react-native: command not found

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!

ANDROID_HOME is not set and "android" command not in your PATH Phonegap

i have installed android bundle and i have configured everything in .bashrc file and even when i say android in command line .. i am getting android manager .. but when i say ionic platform add android i am always getting error as "Error: ANDROID_HOME is not set and "android" command not in your PATH.

may i know how i can fix this error

I faced the same problem, and it's solved.
I think it's issue with the compatibility of the latest cordova with latest android.
As well as you've issue with the android home path.
In .bashrc file
export HOME="/home/indranil"
export ANDROID_HOME="$HOME/software/adt-bundle-linux-x86_64-20140702/sdk"
export PATH="$HOME/software/adt-bundle-linux-x86_64-20140702/sdk/tools:$ANDROID_HOME/platform_tools:$PATH"
Try to download the latest android SDK if you're using older version.
And download Android 4.4.2(API 19) from your android manager.
You can use the latest cordova (4.0.0) but if the issue is still there then use cordova (3.5.0-0.2.7), but if you want to upgrade or downgrade the cordova, remove the existing one using:-
npm uninstall -g cordova (If linux use sudo npm uninstall -g cordova)
If you are using linux don't use
sudo
commad at the time of installing cordoava, if you get any error, run the following commands
sudo chown -R `whoami` ~/.npm
sudo chown -R `whoami` /usr/local/lib/node_modules
sudo chown -R `whoami` /usr/local
Then install cordova without sudo
npm install -g cordova#3.5.0-0.2.7
At the time of creating ionic app and adding android as platform don't use sudo command.
Cordova creates a .cordova directory in the home folder at the time of adding platform. Remove that directory before creating the new ionic application.
And after downloading the android(4.4.2), create an android virtual device using the command:
android avd

I have been struggling with this also (Ubuntu 14.04) and I remember accepting that just getting the cordova build command to work was too difficult for me :-). I was sure my PATHs were correct (tried root and user etc etc) and tried every solution I could find.
A comment by Stoicuta Alexandru On this page solved it for me. I quote:
If ANDROID_HOME is not set, cordova will search for it in home/android-sdk
So just putting my android sdk in the home-folder and (important) naming it android-sdk did it.
Hope to save some people some time...

I had the same problem but I found an alternative method i.e. using the Phonegap Developer App. You could install it to the emulator and use it.

In my case I first created the ionic app and ran other ionic commands using SUDO; that's why it was not working as sudo uses root profile.
This is how i fixed:
delete the /home/user1/.cordova (replace user1 with you user name)
i used "sudo rm" command to delete folder and all of its conents
i deleted the /home/user1/tmp folder so that when we run the cordova again it creates the new tmp folder with proper permission of current user
created new app using "ionic start app5" - this was the main issue as i previously was doing it with sudo
added platform using "ionic platform add android"
executed using "ionic run android"
remember that if from command line you can run "android" command and "java -version" command then above is perfect solution. let me know if you guys need any help from me.

After facing for many day with this issue i follow the instructions above and set my .bash_profile like this on MAC
