Fail to start fresh project

Description

Today I just tested creating new project, with Nitro modules.

after the setup up, I run:

yarn ->> successful
yarn example ios -> failed

error below:

I tried on a Macbook Intel chip still failing, but with different errors:

It seems to be an issue with ruby on your system. I found this issue which looks related CocoaPods/CocoaPods#12326

[ChristopherGabba]

@maitrungduc1410, @mrousavy, @satya164

FINALLY I figured out this error. There is a zero percent chance that I figure this out without the help of GPT.

@maitrungduc1410 I couldn't get nitro's example to build for the life of me (this is part of the reason why I created this issue with Nitro Modules.

I tried following the ruby guide that @satya164 suggested and I did everything it said meticulously and I still got the error above when I tried to run yarn example ios.

The solution for me:

1. npx create-react-native-library@latest react-native-package-name
2. Respond to all the questions from the cli
3. cd react-native-package-name
4. cd example/ios
5. bundle install <------- THIS SOLVED THE ERROR ABOVE
6. cd ../../
7. yarn
8. yarn prepare <-------- If you don't do this step, you get the following error:

[!] Invalid `Podfile` file: 
[!] Invalid `AudioManager.podspec` file: cannot load such file -- nitrogen/generated/ios/AudioManager+autolinking.rb.

 #  from /Users/christophergabba/react-native-audio-manager/AudioManager.podspec:18

11. yarn example ios

You should then get this error:

error Signing for "AudioManagerExample" requires a development team. Select a development team in the Signing & Capabilities editor. (in target 'AudioManagerExample' from project 'AudioManagerExample')
error Failed to build ios project. "xcodebuild" exited with error code '65'. To debug build logs further, consider building your app with Xcode.app, by opening 'AudioManagerExample.xcworkspace'.
info Run CLI with --verbose flag for more details.

12. xed example/ios and fill in your development team.

Now yarn example ios should work (look below if you want to use expo in your example app).

Steps 13 - 20 are if you want expo in your example app:
13. cd example
14. yarn add expo@53.0.0-preview.7 // NOTE THAT EXPO 53 IS IN BETA, BUT FIXES COMPATIBILITY WITH react-native v0.78+
15. yarn add expo-dev-client
16. npx expo install --check (runs expo-doctor and fixes react and react-native versioning
17. npx expo prebuild --clean
18. Change your index.js file:

import { registerRootComponent } from 'expo'; // need to use expo
import App from './src/App';

registerRootComponent(App);

19. Change your metro.config.js file to use expo's:

const { getDefaultConfig } = require("@expo/metro-config");

20: Change your babel.config.js file to use expo's:

const path = require('path');
const { getConfig } = require('react-native-builder-bob/babel-config');
const pkg = require('../package.json');

const root = path.resolve(__dirname, '..');

module.exports = getConfig(
  {
    presets: ['babel-preset-expo'],
  },
  { root, pkg }
);

21. npx expo run:ios --device BOOM runs finally (SHEEEEEESHHH at least 4 hours of my life I'll never get back).Anyway, I hope this helps some other poor souls like myself.

TLDR somewhere either in the docs or via automated through the cli, some of these steps need to be automated. Just my 0.02.

There is also a small chance that I'm a moron and just did something completely wrong.

I ran into this issue a lot of times. What I do is, manually do
cd example/ios
pod install

Open the example project in Xcode and build from there instead of using react-native and it works fine

[ChristopherGabba]

@niteshbalusu11 I'm sure this works, but you shouldn't have to do this, you should be able to build with react-native.
