postgresql - 迁移文件中的 NestJS TypeORM 语法错误

Question

我正在浏览 NestJS 官方文档。我在 Heroku 上设置了 PostgreSQL，与 TypeORM 连接，运行迁移，然后我的应用程序开始崩溃。我尝试了不同的方法并在 github/questions here 上搜索了博客/问题，但没有任何帮助。

这是一个错误:

[Nest] 46723   - 05/10/2020, 6:33:42 PM   [InstanceLoader] TypeOrmModule dependencies initialized +84ms
[Nest] 46723   - 05/10/2020, 6:33:43 PM   [TypeOrmModule] Unable to connect to the database. Retrying (1)... +493ms
/Users/Shared/diploma/be/migration/1589119433066-AddUser.ts:1
import {MigrationInterface, QueryRunner} from "typeorm";
       ^

    at Array.map (<anonymous>)

这是我的ormconfig.json:

  "type": "postgres",
  "url": "postgres://***",
  "ssl": true,
  "extra": {
    "ssl": {
      "rejectUnauthorized": false
    }
  },
  "entities": ["dist/**/*.entity{.ts,.js}"],
  "migrationsTableName": "custom_migration_table",
  "migrations": ["migration/*{.ts,.js}"],
  "cli": {
    "migrationsDir": "migration"
  }
}

迁移是使用 ts-node ./node_modules/.bin/typeorm migration:generate -n AddUser 生成的 我正在使用 nest start --watch 命令启动应用。

迁移文件{TIMESTAMP}-AddUser.ts:

import {MigrationInterface, QueryRunner} from "typeorm";

export class AddUser1589119433066 implements MigrationInterface {
    name = 'AddUser1589119433066'

    public async up(queryRunner: QueryRunner): Promise<void> {
        await queryRunner.query(`CREATE TABLE "users" (...)`, undefined);
    }

    public async down(queryRunner: QueryRunner): Promise<void> {
        await queryRunner.query(`DROP TABLE "users"`, undefined);
    }

}

感谢@Isolated! 我已经更改了 ormconfig.json，所以实体和迁移文件现在看起来像这样，它对我来说工作正常:

"entities": ["dist/**/*.entity{.ts,.js}"],
"migrations": ["dist/migration/*{.ts,.js}"],
