I know it's probably an error while I was setting up the environment. But, I don't know where, and I already redone it twice.

In your project, try to remove node modules and reinstall core-util-is:
rm -rf node_modules
npm install -g npm#latest
npm i core-util-is
I'm also guessing you cloned RN project created on other environment. So if above steps fail, you can try to create new RN project on your current setup - if it is 'compileable' you should be able to run cloned project also.
Another step worth to try - reinstal Node for your platform (https://nodejs.org/en/download/)

I don't know why, but i changed the folder where i cloned the project and it worked. I'm guessing it was because of the spaces and special characters in the path. When i cloned it in C: it worked.

React native cli\build\bin.js can not resolved

I can run my rn project without error.I just create another for test something with
react-native init testapp
and then opened with vs code , run this command as usual
react-native run-android --no-jetifier
it runs the code in emulator.But now it gives error in new project like that.

You didn't enter your project file with "cd" command.You must run your command in your project file.That's why it gives this error.The solution is gonna be in these following steps.
When you initiliaze your project with command "npx react-native init testapp", you need to start metro bundler.(You can find the details about Metro) Before you start metro bundler,You should write down "cd testapp/" command in VS terminal.This will get in your project file.Than,write command which is gonna start metro "npx react-native start".
Secondly,let metro run in its own terminal.Open a new terminal inside your react native project folder.Get into your file again in this terminal too with "cd testapp/".
3.Finally,run your emulator from Android studio.And write "npx react-native run-android" command.(You can go look for how AVD starts with Android Stuido in this link)
Additionally,(VS code screenshot)

Build failed with fresh installed react-native app

Im trying to build an app but run into some problems so tried with a fresh projects that still fails to build. This is my steps:
1) Installing the app with
react-native init Myapp
after that Im running the emulator in android studio and launching the app with:
react-native run-android
and are getting the errormessage below. I have tried to reinstall the react-native cli
npm install -g react-native-cli
reset the cache in gradle with
cd android
gradlew cleanBuildCache
It used to work but since I have had some problems to build the apk I messed around a bit with the gradle. I might have updated something that causes the error. Any help is very welcomed!
here is the errormessage

Is Android SDK installed and are all the required variables set?
Try running in the command line:
adb
If the command is not recognized, then something is wrong with your Android SDK installation.
Follow the link provided in the error for detailed instructions on installing Android SDK.

I think, Developer options closed in your devices first open developer options,
then try this command
react-native init Test
npm i
react-native run-android or ios.

Turn off wifi
Build the app in offline mode
Turn on wifi
Your app should be builded
The reason behind this has been described here: https://github.com/react-native-camera/react-native-camera/issues/2490

Go to android folder and edit build.gradle
set buildToolsVersion to buildToolsVersion = "23.0.1" mine was 30.0.2 when i changed it to "23.0.1" it started working
In the android folder run
gradlew.bat installDebug
and make sure the Build is successful
That should do it go back to your project folder and run
npm run android

What's the solution ..
I hope to find a solution to this problem

Try to clean project this is working for me
for android
$ cd android
$ ./gradlew clean
BUILD SUCCESSFUL in 5s
1 actionable task: 1 executed

Changing port worked for me
You Could try:
react-native run-android --port=8082

Try to clean and rebuild project or you can try to remove whole build folder and build after removing. If it won't help, show your build.gradle, your current information isn't enough to recognise the reason of problem.

React Native
Faced similar issue while building react native app. Running on the different port as the default port (8081) is used by some other app.
Command to build the app.
react-native run-android --port=8082
Solution
Removed extra attribute android:screenOrientation="portrait". If you check the log, it says
lineNumber: 26; columnNumber: 56; Attribute "screenOrientation" bound
to namespace "http://schemas.android.com/apk/res/android" was already
specified for element "activity".
hence removed the same attribute. This was being added multiple times

In android studio,
On the Menu Bar, go to build

Can anyone help me out.

I had exactly the same problem with an ionic project build with the m-ionic yeoman generator, that was uploaded to the ionic cloud.
It started after my computer crashed with a 'blue screen of death', in the middle of a compilation task
What We did to fix the project was to copy and replacing the gradle and corodova files :
.gradle
cordova
CordovaLib
gradle
gradlew.bat
from other ionic>platform>android project that I knew was working fine, beacuse we thought the Cordova files might be corrupted, and early in the project we fixed a similar compilation problem that way. It did not fixed the problem. But then removed the ionic cloud configuration files: ionic.project .
And it worked!!
I hope it could help you!
