PrismaService 上的 Nestjs OnModuleInit 错误

Question

我正在构建 Nestjs CRUD，但是当我启动服务器时，正在记录此错误：属性 'onModuleInit' 在类型 'PrismaService' 中缺失，但在类型 [=29 中需要=].

prisma.service.ts

import { INestApplication, Injectable, OnModuleInit } from "@nestjs/common";
import { PrismaClient } from "@prisma/client";

@Injectable()
export class PrismaService extends PrismaClient implements OnModuleInit {
  async OnModuleInit() {
    await this.$connect();
  }

  async enableShutdownHooks(app: INestApplication) {
    this.$on("beforeExit", async () => {
      await app.close();
    });
  }
}

终端日志

    [09:36:16] Starting compilation in watch mode...

我正在关注 NestJS documentation

我错过了什么吗？

您的 OnModuleInit 方法需要 onModuleInit。 JavaScript区分大小写，所以OnModuleInit和onModuleInit是两种不同的方法
