更新了OS X EI Capitan 出现了source http://ruby.taobao.org/ already present in the cache

localhost:~ LV$ sudo gem install cocoapods
ERROR:  Could not find a valid gem ‘cocoapods‘ (>= 0), 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)

localhost:~ LV$ gem sources -l
*** CURRENT SOURCES ***
 http://ruby.taobao.org/[/code] 
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-0.39.0
Parsing documentation for cocoapods-0.39.0
1 gem installed

ok了
