请教启动后status为Failed

[hnty545]

您好，我使用的vue的webpack模板，启动以后控制台的status为Failed，浏览器打开以后空白，报错如下：
GET http://localhost:3000/main.bundle.js 404 (Not Found)
localhost/:1 Refused to execute script from 'http://localhost:3000/main.bundle.js' because its MIME type ('text/html') is not executable, and strict MIME type checking is enabled.
favicon.ico:1 GET http://localhost:3000/favicon.ico 404 (Not Found)

我是拿您的模板来学习vue和webpack的，请问这可能是什么问题呢？谢谢！
