Question

你好，我在将nestjs连接到mysql时遇到问题。每次如果我改变连接方式都会出现不同的错误。这是conf.ts中的一个

如果尝试使用ocrmconfig.json

{
  "type": "mysql",
  "host": "localhost",
  "port": 3306,
  "username": "root",
  "password": "root",
  "database": "famby_app",
  "entities": ["dist/**/*.entity{.ts,.js}"],
  "synchronize": true,
  "logging": true
}

我的配置文件

    import { TypeOrmModuleOptions } from '@nestjs/typeorm';
import * as dotenv from 'dotenv';
import { UserEntity } from './user/user.entity';
import { join } from 'path';
import { ConnectionOptions } from 'typeorm';

export const typeOrmConfig: TypeOrmModuleOptions = {
  type: 'mysql',
  host: 'localhost',
  port: 3306,
  username: 'root',
  password: 'root',
  database: 'database_test',
  entities: [__dirname + '/../**/*.entity.{js,ts}'],
  synchronize: true,
  logging: true
};

我尝试了所有可能的方法：/

如果遇到和我一样的问题，有人可以帮助我吗？谢谢!!!

您正在尝试在节点中加载ts文件，这是不可能的。用__dirname + '../**/*.entity.{js,ts}行，您将从dist回到根，然后加载.entity.ts和.entity.js的任何东西。因此，您的打字稿源文件正在加载，而Node无法正确解析它们。您应该从该glob中删除ts，或者更好地进行过滤以仅查看您的dist目录（或者说老实话，两者都是最好的）
