[!] 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`. 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/Xcode6.3.1/Xcode.app
pod update --no-repo-update
pod install --verbose --no-repo-update
