尝试运行迁移时的 Typeorm：缺少必需参数：dataSource

我正在尝试运行 TypeORM 迁移ormconfig.json像这样

{
  "name": "default",
  "type": "postgres",
  "host": "ip-is-here",
  "port": 5432,
  "username": "name",
  "password": "12345",
  "database": "db1",
  "synchronize": false,
  "logging": false,
  "entities": ["dist/storage/**/*.js"],
  "migrations": ["dist/storage/migrations/**/*.js"],
  "cli": {
    "entitiesDir": "src/storage",
    "migrationsDir": "src/storage/migrations"
  }
}

via yarn typeorm migration:run
但得到一个错误：

Missing required argument: dataSource

我必须做什么？ 谢谢您的建议！

TypeOrm 已删除ormconfig.json版本支持0.3.0 https://typeorm.io/changelog#030httpsgithubcomtypeormtypeormpull8616-2022-03-17。您应该使用新语法 - 创建ormconfig.ts并为您的数据库指定选项，例如：

export const connectionSource = new DataSource({
    migrationsTableName: 'migrations',
    type: 'postgres',
    host: 'localhost',
    port: 5432,
    username: 'user',
    password: 'pass',
    database: 'somehealthchecker',
    logging: false,
    synchronize: false,
    name: 'default',
    entities: ['src/**/**.entity{.ts,.js}'],
    migrations: ['src/migrations/**/*{.ts,.js}'],
    subscribers: ['src/subscriber/**/*{.ts,.js}'],
});

然后，运行连接后：

await connectionSource.initialize();

您可以通过以下方式获取实体：

const myRepo = connectionSource.getRepository(SomeEntity)

还有你的脚本package.json应该看起来像这样：

"migration:generate": "./node_modules/.bin/ts-node ./node_modules/.bin/typeorm migration:generate -d src/modules/config/ormconfig.ts",
"migration:up": "./node_modules/.bin/ts-node ./node_modules/.bin/typeorm migration:run -d src/modules/config/ormconfig.ts",
"migration:down": "./node_modules/.bin/ts-node ./node_modules/.bin/typeorm migration:revert -d src/modules/config/ormconfig.ts",

命令后，只需在控制台中给出迁移名称，无需 -n 选项
