use_expo_modules! causes Invalid Podfile file: wrong number of arguments (given 2, expect 1)

[chiubaka]

Summary

While attempting to upgrade to Expo SDK 43 in a bare workflow project, I'm having trouble running pod install with the new Podfile. It seems like use_expo_modules! is running some internal Expo code that is then receiving an unexpected number of arguments.

Managed or bare workflow? If you have ios/ or android/ directories in your project, the answer is bare!

bare

What platform(s) does this occur on?

iOS

SDK Version (managed workflow only)

43.0.0

Reproducible demo or steps to reproduce from a blank project

1. Create a new expo project. expo init example
2. Eject the project. cd example && expo eject
3. Attempt to run pod install in the ios/ directory

Observe that pod install fails with the following output:

[!] Invalid `Podfile` file: wrong number of arguments (given 2, expected 1).

 #  from /Users/dchiu/Developer/template/ios/Podfile:11
 #  -------------------------------------------
 #  target 'template' do
 >    use_expo_modules!
 #    config = use_native_modules!
 #  -------------------------------------------

Further investigation reveals that use_expo_modules! itself is being called, and that during this call if @current_target_definition.autolinking_manager.present? is false, so a new Expo::AutolinkingManager is being instantiated. Somewhere in this process, a wrong number of arguments exception is being thrown.

I suspect this was happening due to an outdated version of ruby installed on my system. I upgraded to ruby 3.0.0 using rvm, and subsequently also updated rubygems (gem update --system) and cocoapods (gem update cocoapods). No longer receiving the wrong number of arguments error.
