然后我百度：http://www.jianshu.com/p/6ff1903c3f11
果真，我想想然后执行了作者说的第一步，删除本地Cocoapods文件，然后发现我执行不了接下来的几个步骤了。所以我就执行平时执行安装pod的命令
出现了错误：
localhost:~ LV$ sudo gem install cocoapods
ERROR: Could not find a valid gem ), here is why:
Unable to download data from http://ruby.taobao.org/ - bad response Not Found 404 (http://ruby.taobao.org/specs.4.8.gz)
镜像的http://ruby.taobao.org/明显错误了，因为http
然后我：
localhost:~ LV$ gem sources -l *** CURRENT SOURCES *** http://ruby.taobao.org/
所以我要删除她，更新成https://ruby.taobao.org/
所以我：
localhost:~ LV$ gem sources -a https://ruby.taobao.org/ https://ruby.taobao.org/ added to sources
localhost:~ LV$ gem sources -l *** CURRENT SOURCES *** http://ruby.taobao.org/ https://ruby.taobao.org/
之后我删除http，但是会报错，我尝试了三次都是这样：
localhost:~ LV$ gem sources -remove http://ruby.taobao.org/ source emove not present in cache
但是第四次：
localhost:~ LV$ gem sources --remove http://ruby.taobao.org/ http://ruby.taobao.org/ removed from sources
最好：我开始下载最新的Cocoapods
localhost:~ LV$ sudo gem install -n /usr/local/bin cocoapods Password: Successfully installed cocoapods- Parsing documentation gem installed
【测试】

ok了
