Invalid `Podfile` file: when I try run "pod install"

When I try to run “pod install" in the terminal, I get this same error for all my projects. Last time a complete brew update was performed.

robajz@Roberts-MacBook-Pro ios % pod install

[!] Invalid `Podfile` file: 
[!] Invalid `RNGestureHandler.podspec` file: undefined method `exists?' for File:Class.

Solution

  • So after much pain, i found that if I added this line into the .podspec where the error was coming from

    print RUBY_VERSION

    It was printing out 3.2.0 which I believe has deprecated the "exists" method as mentioned in the error, but I was using a .ruby-version file and rbenv as suggested in the docs and ruby -v was printing out 2.7.5 as expected.

    After hunting through my file system to find where this v3.2.0 could possibly be installed I tried downgrading cocoapods from 1.11.3 -> 1.11.2 and it instantly solved my issue and the print in the podspec was now printing 2.7.5
