建议同学删除掉node_modules文件夹，然后重新执行

npm install安装依赖，执行完npm install，再执行npm install px2rem-loader安装px2rem-loader插件，等待安装完成，再执行npm run dev即可成功

希望可以帮到你！

utils.js里面 var px2remLoader = { loader : 'px2remLoader', options : { remUnit : 50 } }; // generate loader string to be used with extract text plugin function generateLoaders (loader, loaderOptions) { const loaders = options.usePostCSS ? [cssLoader, postcssLoader] : [cssLoader, px2remLoader] 用这个就会出错

同学你好，看报错是因为有依赖没有安装。

建议：

在命令行输入npm install -D px2rem-loader
