webpack +typescript 的使用之 postcss 的问题

Question

新建完typescript 项目之后，一旦.vue 文件里写入了如下代码：

import './../../static/css/aboutus.css';

就会报如下错误：

Failed to compile.

./node_modules/ts-loader!./node_modules/vue-loader/lib/selector.js?type=script&index=0&bustCache!./src/components/About.vue
Module not found: Error: Can't resolve 'postcss-loader' in 'E:\workspace\vue\vue-ts-qbt'
 @ ./node_modules/ts-loader!./node_modules/vue-loader/lib/selector.js?type=script&index=0&bustCache!./src/components/About.vue 1:0-40
 @ ./src/components/About.vue
 @ ./src/router/index.ts
 @ ./src/main.ts
 @ multi (webpack)-dev-server/client?http://localhost:8080 webpack/hot/dev-server ./src/main.ts

我的 webpack.base.conf 配置文件如下：

'use strict'
const path = require('path')
const utils = require('./utils')
const config = require('../config')
const vueLoaderConfig = require('./vue-loader.conf')
var postcss =require('postcss')

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

module.exports = {
  context: path.resolve(__dirname, '../'),
  entry: {
    app: './src/main.ts'
  },
  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$': 'vue/dist/vue.esm.js',
      '@': resolve('src'),
    }
  },
  module: {
    rules: [
            {
        test: /\.tsx?$/,
        loader: 'ts-loader',
        exclude: /node_modules/,
        options: {
          appendTsSuffixTo: [/\.vue$/],
        }
      },
      {
        test: /\.vue$/,
        loader: 'vue-loader',
        options: vueLoaderConfig
      },
      {
        test: /\.js$/,
        loader: 'babel-loader',
        include: [resolve('src'), resolve('test')]
      },
      {
        test: /\.(png|jpe?g|gif|svg)(\?.*)?$/,
        loader: 'url-loader',
        options: {
          limit: 10000,
          name: utils.assetsPath('img/[name].[hash:7].[ext]')
        }
      },
      {
        test: /\.(mp4|webm|ogg|mp3|wav|flac|aac)(\?.*)?$/,
        loader: 'url-loader',
        options: {
          limit: 10000,
          name: utils.assetsPath('media/[name].[hash:7].[ext]')
        }
      },
      {
        test: /\.(woff2?|eot|ttf|otf)(\?.*)?$/,
        loader: 'url-loader',
        options: {
          limit: 10000,
          name: utils.assetsPath('fonts/[name].[hash:7].[ext]')
        }
      }
    ]
  },

}

postcssrc.js 代码如下：

// https://github.com/michael-ciniawsky/postcss-load-config

module.exports = {
  "plugins": {
    // to edit target browsers: use "browserslist" field in package.json
    "autoprefixer": {}
  }
}

package.json 代码如下：
