[react-native] npx expo run:ios Error installing hermes-engine

✔ Config synced
⚠️  Something went wrong running `pod install` in the `ios` directory.
Command `pod install` failed.
└─ Cause: Error installing hermes-engine

 

 

해결:

app.json 내에 아래 설정 추가

"jsEngine": "hermes",

 

In my case, following these steps have me solve this problem:

• Uninstall current ruby: brew uninstall --ignore-dependencies ruby
• Show installed cocoapods: gem list --local | grep cocoapods . It will show a list of cocoapods installed in your computer.
• Uninstall each cocoapods showed step above: sudo gem uninstall cocoapods, sudo gem uninstall cocoapods-core, ...
• Install ruby with brew: brew install ruby
• Recheck ruby is using: gem env. In my case, all lines have ruby version 3 from brew
• Install ffi without arch x86_64 or Rosetta: sudo gem install ffi
• Install cocoapods: sudo gem install cocoapods

Make sure you exported PATH in your environment. I'm using zsh:

• open file config: open ~/.zshrc
• add these lines:

if [ -d "/opt/homebrew/opt/ruby/bin" ]; then
  export PATH=/opt/homebrew/opt/ruby/bin:$PATH
  export PATH=`gem environment gemdir`/bin:$PATH
fi

• save the file and make it effective: source ~/.zshrc

Hope it will help someone face this problem
