这两天摆弄webpack，躺过很多坑，直到今天看了一位博主的文章才得以解决。他对配置中的各个部分做说明。

下面的配置99.9%抄自博主: https://www.cnblogs.com/nianyifenzhizuo/p/10271001.html

安装package.json中的node-sass可能因为网络原因不能成功安装

报错信息有一大串，其中提及python和gyp，其实不用去安装他们。只要执行下面的命令：

npm set sass_binary_site=https://npm.taobao.org/mirrors/node-sass/

npm i node-sass -D

以下为一个vue项目的基本配置：

项目根目录：

package.json

postcss.config.js

.babelrc

项目根目录=>build文件夹

const webpack = require(‘webpack‘)
const { resolve }= require(‘path‘)
const VueLoaderPlugin = require(‘vue-loader/lib/plugin‘)
const HtmlWebpackPlugin = require(‘html-webpack-plugin‘)
const MiniCssExtractPlugin = require(‘mini-css-extract-plugin‘)

const isDev = process.env.NODE_ENV === ‘production‘


let pluginsConfig = [
    new VueLoaderPlugin(),
    new HtmlWebpackPlugin({
        title: ‘my App‘,
        template: resolve(__dirname, ‘../src/index.html‘)
    }),
    new webpack.DefinePlugin({
        ‘process.env‘: {
            ‘NODE_ENV‘: JSON.stringify(process.env.NODE_ENV)
        }
    })
]
if (!isDev) {
    pluginsConfig = pluginsConfig.concat(new MiniCssExtractPlugin({
        filename: "css/[name]_[contenthash].css"
    }))
}

module.exports = {
    mode: process.env.NODE_ENV || ‘production‘,
    entry: resolve(__dirname, ‘../src/index.js‘),
    output: {
        filename: ‘bundle.js‘,
        path: resolve(__dirname, ‘../dist‘)

    resolve: {
        //引入时可以省略后缀

          //@就了代表了src文件夹所在路径
          ‘@‘: resolve(‘src‘),
        }
    },
    module: {
        rules: [{
                test: /\.vue$/,
                loader: ‘vue-loader‘

            {

                use: [
                    isDev ? ‘vue-style-loader‘ : MiniCssExtractPlugin.loader,

                        loader: ‘css-loader‘,
