cocoapods 终极方案

最近各种错误, 全部刷新 再说

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

$ sudo gem update --system // 先更新gem

$ gem sources --remove https://rubygems.org/

$ gem sources -a https://gems.ruby-china.org/

$ gem sources -l //查看ruby地址  

$ sudo gem install cocoapods // 安装cocoapods  

$ pod setup

如果

sudo gem install cocoapods

提示这个

ERROR: While executing gem ... (Errno::EPERM) Operation not permitted - /usr/bin/pod

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

// 还出错的话, 就安装Homebrew 来安装ruby, 中间也是坑, 查.

brew install ruby
