Cocoapod path broken by upgrading macOS #36786
Description
Update: looking from this Cocoapods issue, it seems like this will happen any time your system ruby changes (rvm can also break this). I don't think there's a real fix for this, other than directing users to re-install cocoapods (with their new system ruby).
NOTE: The flutter tool should also catch and gracefully exit on this.
When upgrading to the macOS Catalina beta and installing the beta version of Xcode 11, my cocoapods install was broken, with the following error message:
flutter@macN1 / % flutter doctor

It looks like it is this issue. I fixed it by sudo gem install -n /usr/local/bin cocoapods.
I would guess this is not directly related to using Catalina, but rather having a non-standard beta Xcode installation.
