前段時間還可pod update 呢，昨天有個包更新結果一試不行了，于是在網上搜了一下：
大致步驟如下：
更新 CocoaPods? 升級ruby
重裝? $ sudo gem install cocoapods
結果還是不行，google 了一上發現有不少朋友也遇到過類似的問題，仔細想了一下這個問題應該很好解決可能是自己走錯了路；于是又把問題理了一下，依照 https://github.com/CocoaPods/CocoaPods/issues/1853 提到的
>>>
Ok the problem for me was that (presumably) the update tried to merge CocoaPods-version.yml so in the end it looked like this.

I had the same problem with a private cocoaPod, I updated to 0.29 and I continued with the same problem.
Maybe it's very destructive but for me it was solved with:
$ sudo rm -fr ~/.cocoapods/repos/master
$ pod setup
pod setup 的時候又遇到了問題，就是半天沒反應，我的網絡已是經翻墻的肯定沒問題取消好幾次，一直顯示：
$ pod setup
Setting up CocoaPods master repo
當時感覺可能還是沒有解決，剛好還有一臺MacBook Pro ，于是繼續關注這臺電腦，同時在另一臺電腦上繼續找方法；
等待永遠都是漫長的，差不多過了一個多小時，
$ pod setup
Setting up CocoaPods master repo
Setup completed (read-only access)
終于看到了希望,趕緊到項目目錄下進行測試
pod update
Analyzing dependencies? ? ? >>>>>看到這句我就知道終于弄好了
在另一臺電腦上執行的命令：pod setup 在經歷過漫長的等待后也終于有了正確的結果，所以大家如果在這一步卡住了一定要耐心；

https://github.com/CocoaPods/CocoaPods/issues/1853? I just updated cocoapods to 0.29 (also tested with 0.28) from a super old version (can't remember which one) and now I run into the following error message when I execute 'pod instal'l.
