问题：

[!] Unable to add a source with url `https://github.com/CocoaPods/Specs.git` named `master-1`.  
You can try adding it manually in `~/.cocoapods/repos` or via `pod repo add`.

原因：

是由于我装了多个Xcode导致路径变了，

解决：

hwjdeMacBook-Pro:IJiaXiao_JiaoLian hwj$ sudo xcode-select -switch /Applications/Xcode.app
