项目中nodejs启动服务失败

1.第一次提示

This usually happens because your environment has changed since running npm install
百度说是node-sass安装后环境发生变化。需要重新编译或安装node-sass

解决

- 1.在项目根路径打开管理员模式的cmd
- 2  npm rebuild node-sass
* 2.1 提示Cannot download "https://github.com/sass/node-sass/releases/download/v4.13.1/win32-x64-72_binding.node":
* 3.设置淘宝下载 npm i node-sass --sass_binary_site=https://npm.taobao.org/mirrors/node-sass/
* ok,启动node服务成功
