安装 appium 时一直报下面的错,使用 sudo 安装 appium 能够安装,但运行不起来。
请大神指点一下,如何挽救。。。

解决方法:
1、卸载 appium 和 nodejs(dmg 安装无需卸载)
2、sudo chmod -R 777 /usr/local (不知道是否一定要到这个目录,或许只需要修改到 lib 目录就可以了)
3、重新安装 appium

localhost:temp test2$ npm install -g appium

使用 sudo 安装的 appium,执行的时候报错
ocalhost:temp test2$ appium
error: Appium will not work if used or installed with sudo. Please rerun/install as a non-root user. If you had to install Appium using sudo npm install -g appium, the solution is to reinstall Node using a method (Homebrew, for example) that doesn't require sudo to install global npm packages.
