这是 vue-加载程序(这是vue-webpack模板中的主要插件).

This is the default behaviour for vue-loader (which is the main plugin in the vue-webpack template).

但是，如果需要，您可以将所有CSS提取到一个文件中:

However, if you want to you can extract all CSS into one file:

npm install extract-text-webpack-plugin --save-dev

// webpack.config.js
var ExtractTextPlugin = require("extract-text-webpack-plugin")

module.exports = {
  // other options...
  module: {
    loaders: [
      {
        test: /\.vue$/,
        loader: 'vue'
      },
    ]
  },
  vue: {
    loaders: {
      css: ExtractTextPlugin.extract("css"),
      // you can also include <style lang="less"> or other langauges
      less: ExtractTextPlugin.extract("css!less")
    }
  },
  plugins: [
    new ExtractTextPlugin("style.css")
  ]
}
