vue.js - 设置vue-router 懒加载之后导致vux样式显示不出来

问题描述

问 题

起因是因为项目打包文件过大，因此开始使用vue-router懒加载组件，但是就是因为这个懒加载，编译文件之后，再浏览网站 的时候就导致vux组件样式显示不出来，这是为什么呢，求大神指导！

webpack.base.conf.js

var path = require('path')
var utils = require('./utils')

var projectRoot = path.resolve(__dirname, '../')
const vuxLoader = require('vux-loader')

var config = require('../config')
var vueLoaderConfig = require('./vue-loader.conf')

var entries =  utils.getMultiEntry('./src/*.js'); // 获得入口js文件

function resolve (dir) {
  return path.join(__dirname, '..', dir)
}

let webpackConfig = {
  entry: {
    xmlive: './src/main.js',
    xiju:'./src/xiju.js'
  },
  // entry:entries,
  output: {
    path: config.build.assetsRoot,
    filename: '[name].js',
    publicPath: process.env.NODE_ENV === 'production'
      ? config.build.assetsPublicPath
      : config.dev.assetsPublicPath
  },
  resolve: {
    extensions: ['.js', '.vue', '.json'],
    alias: {
      'vue$': 'vue/dist/vue.esm.js',
      '@': resolve('src')
    }
  },
  module: {
    rules: [
      {
        test: /\.vue$/,
        loader: 'vue-loader',
        options: vueLoaderConfig
      },
      {
        test: /\.js$/,
        loader: 'babel-loader',
        include: [resolve('src'), resolve('test')]
      },
      {
        test: /\.(png|jpe?g|gif|svg)(\?.*)?$/,
        loader: 'url-loader',
        query: {
          limit: 10000,
          name: utils.assetsPath('img/[name].[hash:7].[ext]')
        }
      },
      {
        test: /\.(woff2?|eot|ttf|otf)(\?.*)?$/,
        loader: 'url-loader',
        query: {
          limit: 10000,
          name: utils.assetsPath('fonts/[name].[hash:7].[ext]')
        }
      }
    ]
  }
};


module.exports = vuxLoader.merge(webpackConfig, {

  };

  webpackConfig.plugins.push(new HtmlWebpackPlugin(conf));
}

module.exports = webpackConfig

这是打包后的编译输出

这里可以看到x-button组件样式确实显示有问题

就在刚才我把多入口去掉设置成单入口之后，样式就正常了，所以可以知道是多入口导致的问题，但是不知道如何解决！！！

发现网上也有人碰到和我一样的问题，

解决方案

这个问题已经解决了，把多入口的样式css文件打包到同一个文件里面就OK了
