MODULE_NOT_FOUND Nestjs and Swagger

Question

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

Answer 1

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

Answer 2

Swagger v5 is compatible with Nest v8 (@nestjs/core@^8.0.0, @nestjs/common@^8.0.0 etc) Swagger v4 is compatible with Nest v7
