vue打包防止缓存不更新，加时间戳版本号

const MiniCssExtractPlugin = require("mini-css-extract-plugin");
const Timestamp = new Date().getTime();
 
    configureWebpack: {
    plugins :[
      new MiniCssExtractPlugin({
        // 修改打包后css文件名
        filename: `assets/css/[name].${Timestamp}.css`,
        chunkFilename: `assets/css/[name].${Timestamp}.css`
      })
    ],
    output : { // 输出重构  打包编译后的 文件名称  【模块名称.时间戳】
      filename: `assets/js/[name].${Timestamp}.js`,
      chunkFilename: `assets/js/[name].${Timestamp}.js`
    },
  },
