Command PhaseScriptExecution failed with a nonzero exit code
How do I resolve "Command PhaseScriptExecution failed with a nonzero exit code" error when trying to test a project with cocoapods?
This helped me
sudo gem install cocoapods --pre
pod update
I've read BugReport. Problem was similar to mine and it was fixed in 1.6.0.beta.1 (2018-08-16) (changelog).
Updated(thanks to Cœur)
1.6.0 (2019-02-07) Was published
sudo gem update cocoapods
This should work now.
