刚刚升级了系统跟 Xcode, 更新 cocoapods 时出现了以下报错:

[sssMBP:~ rongtaixingzhuo$ pod --version

/Library/Ruby/Gems/2.3.0/gems/cocoapods-1.5.3/lib/cocoapods/command.rb:118:in `git_version': Failed to extract git version from `git --version` ("xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun\n") (RuntimeError)

解决方式:

命令行执行: xcode-select --install
