-bash: /usr/local/bin/pod: /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/bin/ruby。。。。。。

更新Mac系统之后，在终端做 pod 操作之后，输出：-bash: /usr/local/bin/pod: /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/bin/ruby: bad interpreter: No such file or directory

解决方法：

终端输入：sudo gem install -n /usr/local/bin cocoapods
