我跑的时候
$ gem install cocoapods
我明白了
Fetching: i18n-0.7.0.gem (100%)
ERROR: While executing gem ... (Gem::FilePermissionError)
You don't have write permissions for the /Library/Ruby/Gems/2.0.0 directory.
我已经阅读了这篇文章cocoaPods pod安装权限被拒绝
但是答案没有说明是否正确运行sudo你gem install(尽管在问题中被问到 - 即sudo安装cocoaPods是错误的方式还是正常方式？).
