TypeORM - connectionNotFoundError

Question

我用Typescript + Typeorm + Express创建了一个项目。但是当run dev script返回这个错误时：connectionNotFoundError: Connection "default" was not found

我的ormconfig.json：

{
  "name": "default",
  "type": "postgres",
  "host": "localhost",
  "port": 5432,
  "username": "postgres",
  "password": "docker",
  "database": "clean-node-api",
  "synchronize": true,
  "logging": true,
  "entities": [
    "./src/infra/typeorm/entities/*.ts"
  ],
  "cli": {
    "migrationsDir": "./src/infra/typeorm/migrations"
  }
}

我已经克隆了你的仓库并运行了你的代码我找到了回溯

[ERROR] 10:41:29 ConnectionNotFoundError: Connection "default" was not found.

从UserRepository.ts:14:26)引发的错误，

  constructor() {
    this.ormRepository = getRepository(User);
  }

因此，您正在尝试创建一个存储库或管理器，而连接不是established.So，将此语句const repo = await getRepository(User);放入函数中将会起作用！
