Nestjs错误。找不到模块'.app.controller'。

篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Nestjs错误。找不到模块'.app.controller'。相关的知识，希望对你有一定的参考价值。
我似乎找不到错误的来源，因为该应用程序编译时使用的是 Found 0 errors. Watching for file changes. 我在StackOverflow上看到过类似的解决方法，但似乎都没有解决这个问题。
以下是堆栈跟踪
internal/modules/cjs/loader.js:797
throw err;
^
Error: Cannot find module './app.controller'
Require stack:
- C:UsersDELLDocumentsDokunFilesNestjsappapidistsrcapp.module.js
- C:UsersDELLDocumentsDokunFilesNestjsappapidistsrcmain.js
有了下面的appModule，app控制器就可以正常导入到app模块中了。
app.module.ts
import { Module } from '@nestjs/common';
import { MongooseModule } from '@nestjs/mongoose';
import { AppController } from './app.controller';
import { AppService } from './app.service';
import { UserModule } from './user/user.module';
@Module({
imports: [MongooseModule.forRoot(process.env.MONGO_URI,
{
useNewUrlParser: true,
useUnifiedTopology: true
})
, UserModule,
],
controllers: [AppController],
providers: [AppService],
})
export class AppModule { }
app.controller.ts
import { Controller, Get } from '@nestjs/common';
import { AppService } from './app.service';
@Controller()
export class AppController {
constructor(private readonly appService: AppService) {}
@Get()
getHello(): string {
return this.appService.getHello();
}
}
答案
运行。
npm run prebuild
或
rimraf dist
或
rm -rf dist/
再试一次。
我也有同样的问题。

internal/modules/cjs/loader.js:983

}
我注意到控制器确实没有被编译。

但我注意到它的工作原理是 prod:

然后它又自动开始工作了。

因为我已经试过了 nest build && node dist/main.js 事先，我敢肯定 npm run prebuild 又名 rimraf dist (这只是 rm -rf dist/)做到了。由于问题是在 dist 文件夹，这对我来说似乎很合理。不过不知道具体是什么问题。
另一答案
寻找 "incremental": true 在你 tsconfig.json 文件。true则会进行增量更新。将其设置为false，希望能让你省去清理文件的麻烦。dist 每次
