1、配置打包后的文件路径

进入config>index.js把assetsPublicPath:‘/‘改成‘./‘;

build: {
  env: require(‘./prod.env‘),
  index: path.resolve(__dirname, ‘../dist/index.html‘),
  assetsRoot: path.resolve(__dirname, ‘../dist‘),
  assetsSubDirectory: ‘static‘,
  assetsPublicPath: ‘./‘,  
  productionSourceMap: false,
  productionGzip: false,
  productionGzipExtensions: [‘js‘, ‘css‘]
  bundleAnalyzerReport: process.env.npm_config_report
}

2、修改端口号8080为9090，防止端口冲突

进入config>index.js把修改port：9090

module.exports = {
  dev: {
    assetsSubDirectory: ‘static‘,
    assetsPublicPath: ‘/
    host: ‘localhost‘, 
    port: 9090,

3、配置proxyTable 解决开发环境中的跨域问题

module.exports = {
  dev: {
    proxyTable: {
         ‘/dianping‘: {
            target: ‘http://****‘,
            changeOrigin: true,
            pathRewrite: {
              ‘^/dianping‘: ‘/dianping‘ //此字段根据自己项目填写
            }
        }
    }

4、有些图片引用失败在build\webpack.prod.conf.js 的限制limit注释掉

{
  test: /\.(png|jpe?g|gif|svg)(\?.*)?$/,
  loader: ‘url-loader‘,
  options: {
    // limit: 10000,
    name: utils.assetsPath(‘img/[name].[hash:7].[ext]‘)
  }
},

5、去掉打包后不要的.map文件

在config\index.js 中把productionSourceMap:true改成productionSourceMap:false

build: {
  env: require(‘./prod.env‘),
  index: path.resolve(__dirname, ‘../dist/index.html‘),
  assetsRoot: path.resolve(__dirname, ‘../dist‘),
  assetsSubDirectory: ‘static‘,
  assetsPublicPath: ‘./‘,
  productionSourceMap: false,
  productionGzip: false,
  productionGzipExtensions: [‘js‘, ‘css‘]
  bundleAnalyzerReport: process.env.npm_config_report
},

6、build打包发布后css里的图片背景找不到文件

build文件里找到 utils.js 文件，修改如下：

    if (options.extract) {  
         return ExtractTextPlugin.extract({  
           use: loaders,  
           publicPath: ‘../../‘, //解决 build css bg img 加载路径不对问题  (添加的就是这行)
           fallback: ‘vue-style-loader‘  
         })  
       } else {  
         return [‘vue-style-loader‘].concat(loaders)  
       }  
     }
