以前我收到另一个错误，以解决我删除主回购，然后尝试安装pods，我得到以下错误。我检查了其他选项，但它们不适合我。
Mys-MacBook-Pro:~ user$ pod setup
Setting up CocoaPods master repo
[!] /usr/bin/git clone https://github.com/CocoaPods/Specs.git master --depth=1
xcrun: error: active developer path ("/Applications/Xcode.app/Contents/Developer") does not exist, use `xcode-select --switch path/to/Xcode.app` to specify the Xcode that you wish to use for command line developer tools (or see `man xcode-select`)
请让我知道该怎么做。
