CocoaPods 重装

卸载

命令行：
sudo gem uninstall cocoapods

查看Cocoapods其余相关的组件

gem list --local | grep cocoapods

我这儿的显示：

cocoapods-core (1.11.3)
cocoapods-deintegrate (1.0.5)
cocoapods-downloader (1.6.3)
cocoapods-plugins (1.0.0)
cocoapods-search (1.0.1)
cocoapods-trunk (1.6.0)
cocoapods-try (1.2.0)

上面的各组件删除的话，需使用如下命令逐个删除：

sudo gem uninstall cocoapods-core
sudo gem uninstall cocoapods-deintegrate
sudo gem uninstall cocoapods-downloader
sudo gem uninstall cocoapods-plugins
sudo gem uninstall cocoapods-search
sudo gem uninstall cocoapods-trunk
sudo gem uninstall cocoapods-try

重新安装

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