node.js - NestJS/Swagger ralat TS2307: Tidak dapat menjumpai modul '@nestjs/swagger'

Saya sedang mencuba untuk menambahkan Swagger dalam aplikasi NestJS saya, tetapi saya terus menerima ralat bahawa modul tersebut tidak dapat dijumpai. Saya telah menggunakan npm install --save @nestjs/swagger swagger-ui-express untuk menambahkannya ke fail package.json. Sila ambil perhatian bahawa saya juga menggunakan docker dengan docker-compose.

fail main.ts:

import { NestFactory } from '@nestjs/core';
import { SwaggerModule, DocumentBuilder } from '@nestjs/swagger';
import { AppModule } from './app.module';

async function bootstrap() {
  const app = await NestFactory.create(AppModule);
  const whitelistOrigins = process.env.ALLOWED_CORS_ORIGIN;
  app.enableCors({
    origin: (origin, callback) => {
      if (whitelistOrigins.indexOf(origin) !== -1) {
        callback(null, true);
      } else {
        callback(null, false);
      }
    },
    optionsSuccessStatus: 200,
  });


  const options = new DocumentBuilder()
    .setTitle('App')
    .setDescription('The App API;')
    .setVersion('1.0')
    .addTag('app')
    .build();
  const document = SwaggerModule.createDocument(app, options);
  SwaggerModule.setup('api', app, document);

  await app.listen(process.env.PORT);
}
bootstrap();

Ralat ini diterima semasa menggunakan nodemon.

Jawapan #1

Saya berjaya memasang @nestjs/swagger tetapi saya mendapat ralat ini: "error TS2307: Tidak dapat mencari modul '@nestjs/swagger' atau deklarasi jenis yang sepadan."

Saya menambah "@nestjs/swagger": "^5.2.1" dalam package.json dan menjalankan yarn. Saya telah menyelesaikan masalah saya

Jawapan #2

Kadang-kadang docker build bertindak pelik dan tidak dibina dengan betul. Bina semula main anda dan cuba lagi. Saya menggunakan rangka kerja NestJS (expressJS) dan menghadapi masalah yang serupa tetapi diselesaikan melalui pendekatan ini. Modul lain juga menghadapi isu deklarasi yang sama dan telah diselesaikan dengan cara ini juga. Dengan Swagger ^6.0.5.
