通过 npm 安装 Appium 会抛出“权限被拒绝”类型的错误

Question

尝试为 node.js 安装 appium 包，但出现问题，提示 mkdir 权限被拒绝

我尝试以不同的方式运行此命令，并且以 root 用户身份运行并没有太大变化。以前有人遇到过这样的错误吗？

Dmytros-MacBook-Pro:~ root# npm install -g appium
/usr/local/bin/appium -> 
/usr/local/lib/node_modules/appium/build/lib/main.js

> appium-chromedriver@4.0.0 install 
/usr/local/lib/node_modules/appium/node_modules/appium-chromedriver
> node install-npm.js
