在使用npm uninstall -g appium卸载appium的过程中报错

解决办法

1、首先检查谁拥有该目录

ls -la /usr/local/lib/node_modules 

它拒绝访问，因为 node_module 文件夹下的appium归 root 所有

 

 因此需要通过将 root 更改为您的用户来更改此设置，但首先运行下面的命令来检查您当前的用户如何通过 OS X 中的命令行获取活动用户的名称？

id -un或者whoami

然后更换所有者

sudo chown -R [owner]:[owner] /usr/local/lib/node_modules

 或者

sudo chown -R ownerName: /usr/local/lib/node_modules

或者

sudo chown -R $USER /usr/local/lib/node_modules
