升级到7后，Nestjs无法启动。

Posted 2021-04-03

我今天将我的Nest应用程序从6 -> 7升级。在解决了所有的排版错误后，我在启动时得到了奇怪的行为。

然后它就停止了。没有额外的输出。还有很多模块。

以下是相关的包

    "@nestjs/cli": "^7.1.4",
    "@nestjs/common": "^7.0.9",
    "@nestjs/config": "^0.4.0",
    "@nestjs/core": "^7.0.9",
    "@nestjs/graphql": "^7.3.5",
    "@nestjs/jwt": "^7.0.0",
    "@nestjs/platform-express": "^7.0.9",
    "@nestjs/schedule": "^0.3.1",
    "@nestjs/schematics": "^7.0.0",
    "@nestjs/typeorm": "^7.0.0",

供参考，以下是我的 main.ts

import { NestFactory } from "@nestjs/core";
import { AppModule } from "./app.module";
import {
  initializeTransactionalContext,
  patchTypeORMRepositoryWithBaseRepository
} from "typeorm-transactional-cls-hooked";
import { ValidationPipe } from "@nestjs/common";
import helmet from "helmet";

initializeTransactionalContext();
patchTypeORMRepositoryWithBaseRepository();
async function bootstrap() {
  const app = await NestFactory.create(AppModule, { bodyParser: false });
  app.enableCors();
  app.use(helmet());
  app.useGlobalPipes(new ValidationPipe());
  await app.listen(process.env.PORT || 3000);
}
bootstrap();

更新一下。

在我的应用模块里，我试着把所有的应用模块都注释掉 但应用却无法启动。我试着注释掉所有的应用模块，但应用不能启动。都 模块，然后应用程序启动

当我加入 只是 TypeOrmModule.forRoot()，应用程序挂起，不启动。

答案

我有一个有点不满意的答案。我升级Nest包的时候，忘了说nest的一个依赖关系说我的Node版本不够高。我用的是13.x，但它要的是13.6以上的版本，我相信。

我想，"我就用最新的吧"，于是我去了14.x。

当我转到node 13.14.0时，这个问题就解决了。
