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控制台
• 2 npm rebuild node-sass
  • 2.1 提示:
    • Cannot download "github.com/sass/node-s…"

• 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
