命令行npm报错--随时总结

1. npm install -g vue-cli报错

   显示错误代码:

npm WARN deprecated [email protected]: CoffeeScript on NPM has moved to "coffeescript" (no hyphen)
npm ERR! Unexpected end of JSON input while parsing near '...7813},"engines":{"nod'

npm ERR! A complete log of this run can be found in:

本人解决方法：换个网（估计是网络差导致包安装出现了问题）
