cocoapods 卸载|查看|安装

卸载Pod:

step1:（ 指令 which pod ）

which pod: 查看pod命令所在路径,比如为/usr/local/bin/pod，然后执行 rm -rf /usr/local/bin/pod 将pod命令移除

step2:（ 指令 gem list | grep cocoapods ）

执行gem list | grep cocoapods 查看所有与cocoapods相关的已安装的组件，然后挨个卸载

我这里的执行结果是：

cocoapods-core (0.39.0)

cocoapods-downloader (0.9.3)

cocoapods-plugins (0.4.2)

cocoapods-search (0.1.0)

cocoapods-stats (0.6.2)

cocoapods-trunk (0.6.4)

cocoapods-try (0.5.1)

然后我就挨个执行：

gem uninstall cocoapods-core

gem uninstall cocoapods-downloader

gem uninstall cocoapods-plugins

gem uninstall cocoapods-search

gem uninstall cocoapods-stats

gem uninstall cocoapods-trunk

gem uninstall cocoapods-try

step3: 重新安装pod （ 指令 sudo gem install cocoapods ）

执行sudo gem install cocoapods， 提示出错：While executing gem ... (Errno::EPERM) Operation not permitted - /usr/bin/pod

在命令中指定安装到/usr/bin/pods下即可正常安装成功：

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

安装成功，

step4: 查看新安装的pod版本：

pod --version

0.39.0
