webpack 打包，就如下：

强调： 每次修改配置，都要重新打包才能生效。

vue.config.js 中

chainWebpack(config) {
    config.module
      .rule('md')
      .test(/\.md$/)
      .include.add(path.resolve(__dirname, './xxx.md'))
      .add(path.resolve(__dirname, './xxx.md'))
      .end()
      .use('vue-loader')
      .loader('vue-loader')
      .end()
      .use('md-loader')
      .loader(
        path.resolve(__dirname, './md-loader-index.js')
      )

md-loader-index.js

const tocPlugin = require('markdown-it-toc')
const markdown = require('markdown-it')
......
let md = markdown().use(tocPlugin)
......
