NestJS热模块替换:选项对象无效

Question

我正在使用NestJS，并试图按照本页的说明安装热模块更换：https://docs.nestjs.com/recipes/hot-reload

由于我使用的是Nest CLI，所以我遵循了页面的第一部分。然而，在我必须使用nest build --webpack --webpackPath webpack-hmr.config.js命令的时候，我得到了以下错误：

Error  Invalid options object. Watch Ignore Plugin has been initialized using an options object that does not match the API schema.
- options[0] misses the property 'paths'. Should be:
[RegExp | string, ...] (should not have fewer than 1 item)
-> A list of RegExps or absolute paths to directories or files that should be ignored.
- options[1] misses the property 'paths'. Should be:
[RegExp | string, ...] (should not have fewer than 1 item)
-> A list of RegExps or absolute paths to directories or files that should be ignored.

有人知道这可能来自哪里以及如何解决吗？

问题似乎来自于从webpack 4到webpack 5的更新：https://github.com/nestjs/nest/issues/5667

有两种解决方案：

• 等待start-server-webpack-plugin更新，同时不使用HMR
• 降级到webpack 4
