I have tried to create a new project in react-native, After creating when I have opened the iOS project, in libraries folder I could not any libraries and i am not able to run the iOS Project.
I have tried react-native run-ios
Got error like "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 AppName.xcodeproj."
Steps To Reproduce
Lis
cd AppName
open ios/AppName.xcodeproj inxcode and build.
react-native init AppName
I have tried to create multiple projects, but still no luck of getting libraries

I have fixed the issue, by searching over SO and found a solution
In React-native 0.60 +, you need to install pods
Step1: cd ios
Step2: pod install
Step3: pod update
After completion you can run.

if you run
react-native run-ios
it says two commands have failed just like above, they are :

(2 failures)
Any help would be greatly appreciated
1. To fix the first error try:
`rm -rf ./node_modules`
`yarn install` // or npm install
`cd ios && rm -rf ./Pods && rm -rf Pofile.lock && pod install && cd ..`
`npx react-native run-ios`
2. To fix the second error:
try to remove/comment flipper in Podfile
Make sure you have excluded the arm64 architecture for simulators
Note: I had a PhaseScriptExecution error showing up after upgrading Xcode to 13.1:
dyld: Library not loaded: /usr/local/opt/icu4c/lib/libicui18n.67.dylib.
I fixed it with:
brew update and brew install.
If still not working please attach to your question:
full content of Podfile
result of pod install command
full log for react-native run-ios command
Your errors are too generic to debug without the full the full error log.
I always run into this problem. Follow these steps to remove the error.
From the root of the project, do cd ios
pod deintegrate
pod install
If this doesn't help then remove node_modules and then try above after npm install or yarn install, as follows.
On the root of the project, do the following
rm -rf node_modules
npm install / yarn install
cd ios
pod deintegrate
pod install
cd ..
react-native run-ios
I am working on a react native expo project. I was running expo start with no problem until I updated my MacBook. Now, I am facing this error:
Could not get status from Metro bundler. Connect ECONNREFUSED 127.0.0.1:19003
Connecting to Metro bundler failed.
My expo diagnostics is as below:

Ciao, according to this github page, you can:
Restart your computer
Run rm -rf .expo
Instead, according to Expo forum you can try to launch expo start with -c like expo start -c
I am running a simple test to render react native component using enzyme and jest. It's a monorepo setup using lerna for web and mobile with shared components. There is babel, jest config that's shared between packages. The app starts and works successfully using the component that I am testing without any warnings or errors. But for some weird reason when I run a test, I am getting this error
● Test suite failed to run

react and #react-native-community/cli is installed in root node-modules as hoisted by lerna in monorepo. maybe that's why the cli says it's not found.
This is a new react native setup with only the babel and shared node_modules as customised changes code. Only the test fails and it would be great if somebody can give insights. Thanks in advance.
This error was related to enzyme and not react native. It looks like though the enzyme website says it can be made to work with react-native, when using other packages like styled-components it never works. https://github.com/enzymejs/enzyme/issues/1436 - In case anyone is interested to follow the conversation in enzyme repo.
I used https://github.com/callstack/react-native-testing-library instead of enzyme for testing react native and it works smoothly!
I am new to React Native and I am trying to set up my development environment on Windows 8.1 as described in the official documentation.
But I have a problem
Steps :
react-native init AwesomeProject
cd AwesomeProject
react-native start
The app doesn't start correctly and I have this error :
2020-05-26T18:02:48,578: [cli] unable to talk to your watchman on \\.\pipe\watchman-ME! (No such file or directory)

So I figured the problem is with watchman
I found the path on this error weird (\\.\pipe\watchman-ME!) because when executing react-native info, I get the following :

Is my configuration correct ? Because I read other posts, issues and the best recommendation was to reinstall watchman and reboot. I did it multiple times but no changes. If that matters I downloaded the latest CI build, extracted it and added it to the path as described in the docs.
But I keep getting the same error, I tried with existing and new projects as well.
EDIT :
When I start the app, I said it doesn't start correctly, what happens is that it actually opens a white screen with a green bar saying Loading from 10.0.2.2:8081 ..., I read about it (example) and I tried every proposed solution, everything seems all right but I keep getting the same error !
I'm trying to eject my app to generate Android folder. I knew it worked before, but when I type react-native eject in my React Native project's root directory I'm getting:

I've searched for it but every answer points out to that react-native eject is simply the correct form and I couldn't find anything regarding that it doesn't work.

What am I doing wrong?
Since create-react-native-app is deprecated this functionality is no longer needed.
Due to this pr it's gone!
Personaly I don't like it but run npx react-native init YourProjectName and copy over what's necessary.
Update :
I copied to removed code and made a small package : https://www.npmjs.com/package/react-native-eject
Always working for me, first install in your project
yarn add react-native-eject
and then run
react-native eject
make sure you have install yarn in your pc
Type the following command
npx react-native eject
