pod install報錯：
# [cocoapods問題Unable to add a source with url `https://github.com/CocoaPods/Specs.git` named `master-1`](https://my.oschina.net/u/2532095/blog/753609)
終端中： pod install后出現(xiàn)：
Unable to add a source with url `https://github.com/CocoaPods/Specs.git` named `master`.
You can try adding it manually in `~/.cocoapods/repos` or via `pod repo add`.
按照提示：
pod repo add master https://github.com/CocoaPods/Specs.git
仍然不行，是因為安裝多個xcode導(dǎo)致路徑改變
解決： sudo xcode-select -switch 后面當(dāng)前xcode路徑
確保~/.cocoapods/repos下面已經(jīng)有了你的repo获讳，繞過檢查：
pod update --no-repo-update
pod install --verbose --no-repo-update
即可成功儡炼。
