在安装sass插件时报错

$ npm install sass-loader node-sass --save-dev
    
    //返回的报错信息
    npm ERR! code EPERM
    npm ERR! syscall mkdir
    npm ERR! path C:\Users\jinwe\truth_hold\node_modules\node-sass\node_modules
    npm ERR! errno -4048
    npm ERR! Error: EPERM: operation not permitted, mkdir 'C:\Users\jinwe\truth_hold\node_modules\node-sass\node_modules'
    npm ERR!  [OperationalError: EPERM: operation not permitted, mkdir 'C:\Users\jinwe\truth_hold\node_modules\node-sass\node_modules'] { 
    npm ERR!   cause: [Error: EPERM: operation not permitted, mkdir 'C:\Users\jinwe\truth_hold\node_modules\node-sass\node_modules'] { 
    npm ERR!     errno: -4048,
    npm ERR!     code: 'EPERM',
    npm ERR!     syscall: 'mkdir',
    npm ERR!     path: 'C:\\Users\\jinwe\\truth_hold\\node_modules\\node-sass\\node_modules'
    npm ERR!   },
    npm ERR!   stack: "Error: EPERM: operation not permitted, mkdir 'C:\\Users\\jinwe\\truth_hold\\node_modules\\node-sass\\node_modules'",
    npm ERR!   errno: -4048,

    npm ERR!   syscall: 'mkdir',
    npm ERR!   path: 'C:\\Users\\jinwe\\truth_hold\\node_modules\\node-sass\\node_modules',

    > truth_hold@1.0.0 dev C:\Users\jinwe\truth_hold
    > node build/dev-server.js wx
    
     ERROR  Failed to compile with 2 errors

这时运行`npm ls`，会出现这个下面的错误

$ npm ls
    
    //返回的报错信息
    npm ERR! peer dep missing: webpack@^4.36.0, required by sass-loader@8.0.0
    npm ERR! peer dep missing: vue-template-compiler@^2.0.0, required by vue-loader@13.7.3

并且启动项目的时候报错

$ npm run dev
    
    //返回的错误信息，已简化
    ERROR in Cannot find module 'node-sass'
    this.getResolve is not a function

这是因为当前sass的版本太高，webpack编译时出现了错误，这个时候只需要换成低版本的就行  
修改package.json文件，将里面的 "sass-loader"的版本换成更低的版本，比如我现在是`"sass-loader": "^8.0.0"`换成了`"sass-loader": "^7.3.1"`

重新安装sass，再启动项目就成功了

//重新安装sass
    $ npm install sass-loader node-sass --save-dev
    
    //启动项目
    $ npm run dev
