前段时间还可pod update 呢，昨天有个包更新结果一试不行了，于是在网上搜了一下：
大致步骤如下：
更新 CocoaPods 升级ruby
重装 $ sudo gem install cocoapods
结果还是不行，google 了一上发现有不少朋友也遇到过类似的问题，仔细想了一下这个问题应该很好解决可能是自己走错了路；于是又把问题理了一下，依照 https://github.com/CocoaPods/CocoaPods/issues/1853 提到的
重装 $ sudo gem install cocoapods
结果还是不行，google 了一上发现有不少朋友也遇到过类似的问题，仔细想了一下这个问题应该很好解决可能是自己走错了路；于是又把问题理了一下，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.

min: 0.29.0

last: 0.29.0 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 setuppod setup 的时候又遇到了问题，就是半天没反应，我的网络已是经翻墙的肯定没问题取消好几次，一直显示：
$ pod setup
Setting up CocoaPods master repo
当时感觉可能还是没有解决，刚好还有一台MacBook Pro ，于是继续关注这台电脑，同时在另一台电脑上继续找方法；
等待永远都是漫长的，差不多过了一个多小时，
$ pod setup
Setting up CocoaPods master repo
Setup completed (read-only access)
终于看到了希望,赶紧到项目目录下进行测试
pod update
Analyzing dependencies >>>>>看到这句我就知道终于弄好了
在另一台电脑上执行的命令：pod setup 在经历过漫长的等待后也终于有了正确的结果，所以大家如果在这一步卡住了一定要耐心；
解决该问题搜索过的感觉比较好的内容给大家分享一下：
