ERROR in ./src/img/7.jpg 1:0
Module parse failed: Unexpected character '�' (1:0)
You may need an appropriate loader to handle this file type, currently no loaders are configured to process this file. See https://webpack.js.org/concepts#loaders

解决办法：

npm i url-loader@4.1.1 file-loader@6.2.0 -D

webpack.config.js 的 module rules数组中 增加

module: {  // 所有第三方文件模块的匹配规则
        rules:[  // 文件后缀名的匹配规则
            {test:/\.jpg|png|gif$/,use:'url-loader?limit=22229'}
        ]
    }

limit 指定图片大小 ，图片小于等于 limit 22229字节 的时候才会转成 base64
