I'm trying to add Swagger to my Nestjs app. Module not found error is thrown when I'm trying to compile it. I use the same code from Nestjs documentation. This is my main.ts:

async function bootstrap() {
  const app = await NestFactory.create(AppModule);

  const config = new DocumentBuilder()
    .setTitle('Cats example')
    .setDescription('The cats API description')
    .setVersion('1.0')
    .addTag('cats')
    .build();
  const document = SwaggerModule.createDocument(app, config);
  SwaggerModule.setup('api', app, document);

  await app.listen(3000);
}
bootstrap();

This is the error:

internal/modules/cjs/loader.js:883
  throw err;
  ^

Error: Cannot find module '@nestjs/core/router/route-path-factory'

I'm using Node 14.15.1, @nestjs/swagger 5.0.0, swagger-ui-express: 4.1.6

Update latest version of @nestjs/platform-express, @nestjs/common,@nestjs/core (8.0.0) solve my problem. It seems like nestjs/cli uses previous version of nestjs

Quick Fix ====>>

Update your dependencies to reflect:

{
"@nestjs/common": "^8.0.0",
"@nestjs/config": "^1.1.5",
"@nestjs/core": "^8.0.0",
"@nestjs/platform-express": "^8.0.0",
}

Update your dev dependencies to reflect:

   {
        "@nestjs/cli": "^8.0.0",
        "@nestjs/schematics": "^8.0.0",
        "@nestjs/testing": "^8.0.0",
    }

This fixed my problem. Let me know if this works for you!
