2、下面还原一下报错时的背景

在学习Vue的过程中，之前都是使用静态服务器工具包发布的。一直都没有问题。命令如下：

0) npm install -g serve
1) serve dist
2) 访问：http://localhost:5000

后来，尝试使用动态web服务器(Tomcat)发布项目，打包时就报错了。以下是我的操作步骤：

0) 修改build/webpack.prod.conf.js
    output:{
        publicPath:'/vue_demo/' // 打包文件夹的名称
    }
1) npm run build就会出现标题所示的错误。

3、定位和总结

  1. 根据报错信息中的 WebpackOptionsValidationError 为关键字百度到了文章，猜到可能是webpack配置出了问题。找了以下 output 的publicPath 属性写成了public。我丢。。。
  2. 引以为戒！
