postgresql - TypeORM 迁移给出 Maximum call stack size exceeded error with Postgres

Question

运行迁移时，出现以下错误。我最初在一个项目中有这个——现在我创建了一个新的空白项目，但仍然出现错误。这是 ormconfig.ts:

import { DataSource } from 'typeorm';

const env = {
  "DB_HOST":"localhost",
  "DB_PORT":5432,
  "DB_USERNAME":"postgres",
  "DB_PASSWORD":"postgres",
  "DB_DATABASE":"task-management",
}

export const connectionSource = new DataSource({
  migrationsTableName: 'migrations',
  type: 'postgres',
  host: env.DB_HOST,
  port: env.DB_PORT,
  username: env.DB_USERNAME,
  password: env.DB_PASSWORD,
  database: env.DB_DATABASE,
  logging: false,
  synchronize: false,
  name: 'default',
  migrations: ['migrations/**/*{.ts,.js}'],
});

我运行迁移:typeorm-ts-node-esm migration:run -d migrations/ormconfig.ts

出现以下错误:

 Error during migration run:
    RangeError: Maximum call stack size exceeded

        at /Users/christianayscue/Desktop/nestjsClass/nestjs-task-management/node_modules/src/util/DirectoryExportedClassesLoader.ts:30:17

我假设在 DirectoryExportedClassesLoader.ts 中存在一些循环依赖导致无限循环，所以我在 DirectoryExportedClassesLoader.ts 的第 26 行放置了一个 console.log(JSON.stringify(exported))，现在我得到:

TypeError: Converting circular structure to JSON
    --> starting at object with constructor 'DataSource'
    |     property 'driver' -> object with constructor 'PostgresDriver'
    --- property 'connection' closes the circle
    at JSON.stringify (<anonymous>)
    at loadFileClasses (/Users/christianayscue/Desktop/nestjsClass/typeormTest/src/util/DirectoryExportedClassesLoader.ts:29:25)

如果存在循环依赖，DirectoryExportedClassLoader.js 似乎保证会得到超出最大调用堆栈大小的错误，因为它在遇到对象属性时是自递归的。

请帮忙!

从 DataSource 配置对象更改此条目可解决问题。

migrations: []

这是经过大量反复试验才能解决的问题之一...
