错误现象 :

主要是node-sass版本问题，他的版本看和node版本对应

npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! node-sass@4.13.1 postinstall: node scripts/build.js
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the node-sass@4.13.1 postinstall script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.
npm ERR! A complete log of this run can be found in:
npm ERR! C:\Users\cpucode\AppData\Roaming\npm-cache_logs\2021-06-10T13_48_01_433Z-debug.log

解决方案 :

查看对于版本信息

https://hub.fastgit.org/sass/node-sass

都可以看到node和node-sass对应的版本信息

查看版本

node -v

与 4.14 对应

卸载残留问题

先清依赖残留，否则安装不上

npm rebuild node-sass

npm uninstall node-sass

类似于这种错误不用管

run npm audit fix to fix them, or npm audit for details

安装 4.14的

npm install  node-sass@4.14

安装其他依赖：

npm install

启动项目：

npm run dev
