報錯資訊如下

Module Error (from ./node_modules/vue-loader/lib/index.js):
vue-loader was used without the corresponding plugin. Make sure to include VueLoaderPlugin in your 
webpack config.

原因

參考官方文件
https://vue-loader.vuejs.org/migrating.html#a-plugin-is-now-required

解決辦法如下

// webpack.config.js
const VueLoaderPlugin = require
 
('vue-loader/lib/plugin')

module.exports = {
  // ...
  plugins: [
    new VueLoaderPlugin()
  ]
}
