Can not perform `pod install` under el capitan (15A279b)

Question

I ran pod install with El Capitan and got this error:

Errno::EPERM - Operation not permitted - /Users/../Pods/Pods.xcodeproj/xcuserdata/root.xcu         


        

Answer 1

I had to update the system before 'gem install' otherwise I got this:

ERROR: Error installing cocoapods: activesupport requires Ruby version >= 2.2.2.:

Here's what worked for me:

gem update --system
sudo gem install -V -n /usr/local/bin cocoapods
pod install

I actually needed to just update:

pod update
