在Next.js生成过程中出错：模块解析失败：意外字符'＃'

Question

在Next.js应用程序（带有自定义server.js和next.config.js）中进行“纱线构建”之后，终端显示奇怪的错误。

Module parse failed: Unexpected character '#' (1:0)
You may need an appropriate loader to handle this file type.
> #!/usr/bin/env node
| /**
|  * @license

> Build error occurred
Error: > Build failed because of webpack errors```

What's wrong with that?
