Error
xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun
error: "" unsupported
Solution:
- Re-install XCode from App Store (~20 minutes)
- Open XCode and agree to lice agreement
- Allow it to "Instal components..."
This resolved my problem, but optionally you can try the following:
- xcode-select --install
- sudo xcodebuild -license
- xcode-select --reset
