How to get cocoapods work on Yosemite

今天升級了Mac OS X 10.10-Yosemite之後運行pod install遇到下面的錯誤： /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/fileutils.rb:245:in 'mkdir': Permission denied - /Library/Ruby/Gems/2.0.0/extensions/universal-darwin-14 (Errno::EACCES)

一番折騰後找到解決方案以下：

1. 分別執行下面命令卸載cocoapods和xcodeproj，若是你的機器上面有多個版本，選擇All versions卸載 
   $ sudo gem uninstall cocoapods

   $ sudo gem uninstall xcodeproj

2. 分別執行下面命令安裝xcodeproj和cocoapods 
   $ sudo gem install xcodeproj

   $ sudo gem install cocoapods

接下來嘗試執行pod install，若是您還遇到下面的錯誤Error loading the plugin with path '/Library/Ruby/Gems/2.0.0/gems/cocoapods-plugins-0.3.1/lib/cocoapods_plugin.rb'. Errno::EACCES - Permission denied - /Library/Ruby/Gems/2.0.0/extensions/universal-darwin-14

運行命令$ gem update --system便可。

若是您還遇到這樣的錯誤Unable to load a specification for the plugin '/Library/Ruby/Gems/2.0.0/gems/cocoapods-try-release-fix-0.1.2'，運行命令sudo gem uninstall cocoapods-try-release-fix後再運行sudo gem install cocoapods。
