设置vue-router 懒加载之后导致vux样式显示不出来

Question

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: {

  },

        loader: 'url-loader',
        query: {
          limit: 10000,

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，

Answer 1

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

Answer 2

你可以对比一下异常按钮的样式，是被覆盖了还是没有打包进来
