Steps to reproduce

  1. On an M1 Mac...
  2. Clone the repo at https://github.com/wmleler/thematrix
  3. Enable macos for the project by running flutter create --platforms=macos .
  4. Ensure that macos is enabled by running flutter config --enable-macos-desktop
  5. Install Cocoapods from scratch using sudo gem install cocoapods (as instructed by https://guides.cocoapods.org/using/getting-started.html#installation, which is pointed to by flutter doctor)
  6. Attempt to run the app using flutter run -d macos

Expected behavior

You expect the app to run (it's out of date and has errors after running, but it still should be able to run).

Actual behavior

You get an error building. The main error is:

/Library/Ruby/Gems/2.6.0/gems/ffi-1.15.3/lib/ffi/library.rb:275: [BUG] Bus Error at 0x00000001042fc000

Googling for that error will eventually lead you to CocoaPods/CocoaPods#10723 (comment)

So then, you run:

sudo arch -x86_64 gem install ffi

But when you run the app again, you still get the same error.

It turns out that you can get it working by applying the following patch to flutter_tools:

diff --git a/packages/flutter_tools/lib/src/macos/cocoapods.dart b/packages/flutter_tools/lib/src/macos/cocoapods.dart

... but presumably we shouldn't be unconditionally running that.

    So, we're already detecting a similar error, and recommend a similar workaround: #94385

    @tvolkert I wonder, does arch -x86_64 sudo gem install ffi work (with the sudo after the arch call)?

    I hit this today and followed instructions from https://stackoverflow.com/questions/69867593/flutter-run-crash-on-ios-error-running-pod-install

    To do:

    sudo arch -x86_64 gem install ffi

arch -x86_64 pod install

    in the "ios" folder, and then flutter build ios worked just fine. :)

    It also may be Google-mac specific? I don't know if we have a different ruby than default on these machines (I know we used to have a non-standard python which sometimes caused problems).
