[!] 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`. 是由于装了多个Xcode导致路径变了, 解决:$ sudo xcode-select -switch /Applications/Xcode6.3.1/Xcode.app pod update --no-repo-update pod install --verbose --no-repo-update
