因?yàn)殡娔X升級(jí)了，突然準(zhǔn)備升級(jí)一下第三方框架，發(fā)現(xiàn)cocoapods用不了了。故重新安裝一下，但是過程還是出現(xiàn)很多問題，故來寫一篇文章記錄一下。
安裝cocoapods需要使用ruby環(huán)境，因?yàn)橐郧鞍惭b過，所以不需要再安裝了。如果沒有就去自行百度吧。因?yàn)橐话鉳ac系統(tǒng)都自帶安裝了。如果不知道自己有沒有ruby，可以用ruby -v 查看當(dāng)前ruby版本。
安裝：
首先 查看你的ruby源
$gem sources -l
我的返回的是我以前安裝的源
*** CURRENT SOURCES ***
https://ruby.taobao.org/
以前就是用的淘寶的，但是后面的改了，所以我就改了一個(gè)源。首先刪除原來的源。
gem sources --remove https://ruby.taobao.org/
執(zhí)行命令后：
https://ruby.taobao.org/ removed from sources
接下來就要添加可用的鏡像源
$ gem sources -a http://rubygems-china.oss.aliyuncs.com
執(zhí)行命令后：
http://rubygems-china.oss.aliyuncs.com added to sources
此時(shí)就可以安裝cocoapods
$ sudo gem install cocoapods
但是我這里出現(xiàn)了問題如下：
Fetching: gh_inspector-1.0.2.gem (100%)
Successfully installed gh_inspector-1.0.2
Fetching: fourflusher-2.0.1.gem (100%)
Successfully installed fourflusher-2.0.1
Fetching: xcodeproj-1.3.3.gem (100%)
ERROR:While executing gem ... (Errno::EPERM)
Operation not permitted - /usr/bin/xcodeproj
瞬間懵逼，不是說好的可以的嗎？怎么還出錯(cuò)，于是自行百度，需要修改下命令，其實(shí)就是放到安裝目錄下去
$ sudo gem install -n /usr/local/bin cocoapods
此刻執(zhí)行完后會(huì)出現(xiàn)

此時(shí)安裝成功了，趕快去試試你的cocoapods吧
$ pod search AFN（搜索AFN）就會(huì)出現(xiàn)很多相關(guān)的第三方庫。
是否解決了你的問題了呢？有的話就留言吧！??
