OS X升级到10.10之后使用pod出现问题的解决方法

最新对mac 10.10的强大功能好奇，于是将系统升级到了10.10，结果发现使用pod出现了下面的问题：

/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- xcodeproj/prebuilt/universal.x86_64-darwin14-2.0.0/xcodeproj_ext (LoadError)
	from /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:55:in `require'

	from /usr/bin/pod:23:in `load'
	from /usr/bin/pod:23:in `<main>'

经过一番乱搜，具体的解决步骤如下:

1. 打开 Xcode 6
2. 进入 Preferences
3. 点击Locations选项
4. 将 Command Line Tools 版本变成 Xcode 6.0
5. 卸载 cocoapods，在终端中输入

$ sudo gem uninstall cocoapods

6. 安装xcodeproj，在终端中输入

$ sudo gem install xcodeproj

7. 安装cocoapods，在终端中输入

$ sudo gem install cocoapods

8. 测试pod是否安装成功，在终端中输入

$ pod --version
