I've started React-Native programing recently. When I want to create a new project based on a guidence of "https://reactnative.dev/docs/environment-setup" and want to run in xcode 12.5 this error is shown:
bash: Progects/Trading: No such file or directory

I' ll be thankfull of guiding me

Make sure you installed pods. If you already installed then delete the pods folder and podfile.lock inside the ios.
Run this command on your terminal:
cd ios && pod install && cd ..
Open your ios folder through finder and open .xcworkspace file and run from their

I already setup my android studio and sdk manager, avd manager like it's shown in doc also I already set path but it's still showing that error, anyone know why? Can anyone help please?

You can fix it by using the command :
react-native doctor
This command shows all issues that need to be fixed.
Press f to fix the issues and don't forget to restart your windows
And after then open the emulator before running your project.
Once emulator opened,
run command:
react-native run-android
After fixed:
Don't forget to give me an upvote if that's work.

In My Case, I have to re-run the command in the same terminal where you are trying to run npx react-native run-android
Step 1. paste the source command first
source ~/.bash_profile OR source ~/.bashrc
Step 2. RUN Next command
npx react-native run-android

set your AVD manager path and JDK path like this , also you have to add Android Home path

React Native, why react-native run-android not working?

I'm trying to run react native run-android after I update my project file, but whenever I run react-native it throws an error. When I created that project and that command it worked fine but when I edit and add some files like apps/redux, apps/components, screens etc it stopped working. Can anyone tell me why it's not working?

you either need to create a virtual device or connect a physical device with USB debuging enabled (https://developer.android.com/studio/debug/dev-options).
To create a virtual device, open android studio and select AVD manager from Configure menu and create a new virtual device downloading required packages.

In case you are using a virtual device with Android studio then try to manually run the emulator BEFORE react-native run-android.
(open android studio > Tools > AVD Manager > Create Virtual Device)

Or repeat the official installation guide:

build failed react-native 0.6.5 We ran "xcodebuild" command but it exited with error code 65

I'm having this problem "error Failed to build iOS project. We ran "xcodebuild" command but it exited with error code 65. To debug build logs further, consider building your app with Xcode.app, by opening starter.xcodeproj. Run CLI with --verbose flag for more details." since I pulled the latest update from the other colleague, I can't run the project in my simulator, but my colleagues side works fine.
I've tried to change the build system to legacy build system.
Clone the project again.
remove the build folder under iOS folder, and run again.
remove the node module folder and run again.
I have tested in different device is not working too.

Module hmrclient is not registered react native, why is this happening and how to fix it?

So I have rage shaken my tablet and in dev settings, I have my JS dev mode to true yet, live/hot reloading does not work. Funny thing is, when I run the app on a colleague's Mac (the same model and everything) - it works fine.
I don't know what or why this is happening.
I've tried:
cd android && ./gradlew clean
then cd .. && react-native run-android
https://github.com/expo/expo/issues/916
and also:
rm -rf node_modules && npm install
cd android && ./gradlew clean
React-Native Module HMRClinet is not a registered callable module(calling enable)
import com.facebook.react.BuildConfig;
react-native run-android
Unable to load script from assets index.android.bundle on windows
None of the above solutions work.
Do you guys know how I can solve this issue?

This issue come due to development server error.
Follow some steps to resolve this issue.
Step 1:
adb kill-server
adb start-server
then check your device/emulator is visible on command prompt or not.
adb devices
Step 2
Clean your gradle compiler files, some file may be corrupt.
android/gradlew clean
Step 3:
Remove application from your device/emulator.
Step 4:
react-native run-android
Now issue will be resoled :)
