MAC OS升级到10.11(OS X EICAPTION)以后CocoaPods不能正常使用的问题解决

昨晚回家以后开始升级系统到10.11，下载了一整个晚上以后终于在早上下载完毕，早上带到公司，想查一个第三方库的时候却遇到了问题：

guoyufudeMacBook-Pro:~ GuoYufu$ pod search VKVideoPlayer
-bash: pod: command not found

接着尝试：

guoyufudeMacBook-Pro:~ GuoYufu$ gem sources -l
*** CURRENT SOURCES ***

http://ruby.taobao.org/

这里没错。

guoyufudeMacBook-Pro:~ GuoYufu$ pod help
-bash: /usr/local/bin/pod: /usr/local/opt/ruby/bin/ruby: bad interpreter: No such file or directory

而后基本肯定是系统升级以后致使CocoaPods不能正常使用。继续查找解决方案：

1.首先考虑从新安装CocoaPods：

guoyufudeMacBook-Pro:~ GuoYufu$ sudo gem install cocoapods
Password:
ERROR:  While executing gem ... (Errno::EPERM)
    Operation not permitted - /usr/bin/pod

失败。

2.继续根据报错信息查找解决方法，运行查到的：

sudo gem install -n /usr/local/bin cocoapods

提示：

Successfully installed cocoapods-0.38.2
Parsing documentation for cocoapods-0.38.2
1 gem installed

莫非成功了？

尝试：

pod search VKVideoPlayer

能够正常执行。

尝试更新一下CocoaPods的版本：

guoyufudeMacBook-Pro:~ GuoYufu$ sudo gem install cocoapods
Password:
ERROR:  While executing gem ... (Errno::EPERM)
    Operation not permitted - /usr/bin/pod

仍是报错。

3.索性按照最初安装的步骤所有来一遍：

安装Homebrew

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

安装Ruby后从新安装CocoaPods

brew install ruby

sudo gem install cocoapods

终于再也不报错了。
