  ,
  "keywords": [],
  "author": "",
  "license": "ISC",
  "devDependencies": 
    "css-loader": "^2.1.1",

loader顺序必须是 style-css 再到 css-loader
file-loader

url-loader

const path = require(‘path‘);
module.exports = 
    entry: 
        app: ‘./src/app.js‘
    ,
    output: 
        filename: "bundle.js",
        path: path.join(path.resolve(__dirname), ‘dist‘)
    ,
    mode: "development",
    module: 
        rules: [
            
                test: /\.js$/,
                exclude: ‘/node_modules/‘,
            ,
            
                test: /\.css$/,
                use: ["style-loader", "css-loader"] 
            
        ]
    
;
