Hello, today we are going to solve the error that occurs when trying to build an iOS app in react native version 72 / Expo 48.

The error is as follows:

:warning: Something went wrong running `pod install` in the `ios` directory.
Command `pod install` failed.
└─ Cause: Invalid `Podfile` file: 783: unexpected token at ''.

# from ../ios/Podfile:42
# -------------------------------------------
# use_expo_modules!
> config = use_native_modules!
# -------------------------------------------

To resolve it, follow these steps:

  • Update Ruby to version 3.1
brew install ruby@3.1
  • Add the PATH for Ruby (the command will appear on the screen after Ruby installation is complete):
echo 'export PATH="/opt/homebrew/opt/ruby@3.1/bin:$PATH"' >> ~/.zshrc
  • Reinstall CocoaPods
gem install cocoapods
  • Add the PATH for CocoaPods
echo 'export PATH="/opt/homebrew/lib/ruby/gems/3.1.0/bin:$PATH"' >> ~/.zshrc
