遇到了同样的问题，请问有解决方法吗？

参考plotly/dash-component-boilerplate#12 (comment)

This was broken by a webpack update, see webpack/webpack#8082

A workaround for now is to update both, webpack and webpack-cli in package.json:

    "webpack": "^4.20.2",
    "webpack-cli": "^3.1.1",

在package.json的dependencies中加入上述两行，然后重新npm install（为了排除问题，我删除了之前生成的node_modules文件夹），最后再npm run dev就可以使用了，默认端口是3900。

这个方案目前对我有效，你们可以试一试，希望对你们会有帮助~ @urzz @superman66

@Magnetic2014 感谢！欢迎提个 PR

@superman66 package.json merge之后json parse failed，少了个逗号

@urzz
抱歉，提交前一不小心把逗号删掉了。
补上逗号以后你那里可以正常运行吗？
