MacOS react native error bundler: failed to load command: pod

Question

I tried creating a new project in react native:

 npx react-native@latest init myApp

> gem which cocoapods

/Users/nameUser/.rbenv/versions/3.2.2/lib/ruby/gems/3.2.0/gems/cocoapods-1.13.0/lib/cocoapods.rb

When creating the project I get this:

error Looks like your iOS environment is not properly set. Please go to https://reactnative.dev/docs/environment-setup?os=macos&platform=android and follow the React Native CLI QuickStart guide for macOS and iOS.

Can you give me a hand?

Answer 1

I'm also experiencing this, under an older version of Ruby. I think it's related to this recent commit to the react-native repo:

https://github.com/facebook/react-native/commit/ce39931bc2b02f13cbc5751ba4d4a6dbc07bc91a

I think I've got a workaround while this is addressed (unless there's some new prerequisite that's not documented, I'm not au fait with the Ruby ecosystem)

The command that's failing, after checking the @react-native-community/cli package, is bundle exec pod install.

If you re-run the init project command, let it fail, then cd YourProjectName/ios/ && pod install, it should work for you as if the official installer completed successfully.

From there you can yarn start and run the application on iOS, Android etc.

It seems to be a bug in a new version of activesupport. You can downgrade until you find the right version. You will probably have to update your Podfile formatting to match the different version.

For example:

gem uninstall activesupport -v 7.1.1
gem install activesupport -v  7.0.8
