我正在逐步遵循教程，当我进入 run 部分时npx mikro-orm migration:create，出现此错误

TypeError [ERR_INVALID_ARG_TYPE]: The "key" argument must be of type string or an instance of Buffer, TypedArray, DataView, or KeyObject. Received null

I can't find any solution on google, and the tut doesn't point out how to login to postgresql on the app

您缺少一些配置，很可能是user或password字段。这是相关问题：

https://github.com/mikro-orm/mikro-orm/issues/866

如果您不提供它们，MikroORM 将为给定驱动程序选择默认值，即postgres用户和空密码 - 您的 postgres 安装显然没有该用户的空密码。

如果您使用 docker 创建 postgres 服务器，您可以通过以下方式使其接受空密码：

  postgre:
    image: postgres:12.4
    ports:
      - 5432:5432
    environment:
      POSTGRES_HOST_AUTH_METHOD: trust   <-- here

似乎您没有指定要在其中传递的对象的passwordor属性。userMikroORM.init

这应该工作

export default {
  entities: [Entity],
  dbName: "yourDatabaseName",
  type: "postgresql",
  user: "yourUserName",
  password: "yourPassword"
} as Parameters<typeof MikroORM.init>[0];
