我正在尝试生成迁移。我已经将这些行添加到package.json中

"typeorm": "node --require ts-node/register ./node_modules/typeorm/cli.js  --config src/config/configuration.ts",
 "migration:generate":"npm run typeorm migration:generate -- -n"

我有一个configuration. ts文件，而不是ormconfig.json，它看起来像这样。

import { join } from 'path';

export default () => {
  const host = process.env.DB_HOST;
  const port = process.env.DB_PORT;
  const username = process.env.DB_USERNAME;
  const password = process.env.DB_PASSWORD;
  const database = process.env.DB_DATABASE;

  return {
    database: {
      type: 'mariadb',
      host,
      port,
      username,
      password,
      database,
      entities: ['dist/**/*.entity{.ts,.js}'],
      synchronize: false,
      migrations: ['/src/migration/**/*.ts'],
      keepConnectionAlive: true,
      charset: 'utf8mb4',
      cli: {
        migrationsDir: '/src/migrations',
      },
    },
  };
};

运行命令时

npm run migration:generate -- softDeleteUser

有这个错误

> user-service@0.0.1 migration:generate
> npm run typeorm migration:generate -- -n "softDeleteUser"

> user-service@0.0.1 typeorm
> node --require ts-node/register ./node_modules/typeorm/cli.js  --config src/config/configuration.ts "migration:generate" "-n" "softDeleteUser"

Error during migration generation:

有什么建议吗？

您是否尝试导出配置，例如：

export = ORMConfig;

我也遇到过同样的错误，所以我试着按照文档上说的去做。我把我的数据库配置导入到app.module imports里面，如下所示：

`import { Module } from '@nestjs/common';
import { TypeOrmModule } from '@nestjs/typeorm';

@Module({
  imports: [
    TypeOrmModule.forRoot({
      type: 'mysql',
      host: 'localhost',
      port: 3306,
      username: 'root',
      password: 'root',
      database: 'test',
      entities: [],
      synchronize: true,
    }),
  ],
})

但不幸的是，这不是原因。真实的的原因是在我的实体文件中，我在实体表中放置了列。我有：

@Column({
    type: 'float',
    precision: 6,
    scale: 2,
  })
  price: number;

而不是：

@Column({
    type: 'decimal',
    precision: 6,
    scale: 2,
  })
  price: number;

因为只有小数才具有精度和刻度属性所有变体都在此处描述：https://typeorm.io/entities#column-options

这在我的情况下工作：-

*inside app.module.ts*
    imports: [
    ConfigModule.forRoot({isGlobal: true}),
    TypeOrmModule.forRootAsync({
    useClass: DatabaseConnectionService //DatabaseConnectionService is 
    //the  file containing the connection code
    }) ,
    UserModule
    ]
