xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun

During flex deployment on mac a probably gcloud error:

Beginning deployment of service [default]...
Building and pushing image for service [default]
xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun
Started cloud build [9eb0c5e3-052b-4b58-b0b7-64e250bf872f].

Likely gcloud needs to predetect this condition and respond accordingly.
