Is it possible to somehow specific the version of CocoaPods I\'d like to use when upgrading or installing a Podfile? I\'ve encountered several times where Podfiles work correctl

Answer 1

the ultimate solution:

1. run a bash script to completely uninstall your current verison (Optinal)

   for i in $( gem list --local --no-version | grep cocoapods  ); do
       sudo gem uninstall $i;
   done   
   sudo gem uninstall xcodeproj
   

2. install a specific verison of CocoaPod

   gem install cocoapods -v 0.39.0
