【问题描述】：

我最近在使用 NestJs 和 typeORM，但在运行我的 Nest 应用程序时出现错误。它会产生这个错误

/home/backend/src/migrations/1611061187746-loadAllEntities.ts:1
import  MigrationInterface, QueryRunner  from 'typeorm';
       ^

SyntaxError: Unexpected token 
    at Module._compile (internal/modules/cjs/loader.js:723:23)
    at Object.Module._extensions..js (internal/modules/cjs/loader.js:789:10)

指向我生成的迁移 ts 文件的错误

//xxxxx-migration.ts

import MigrationInterface, QueryRunner from "typeorm";

export class migrationMessageDetail1611143681385 implements MigrationInterface 
    name = 'migrationMessageDetail1611143681385'

    public async up(queryRunner: QueryRunner): Promise<void> 
        await queryRunner.query("CREATE TABLE `detail_pricing` (`id` int NOT NULL AUTO_INCREMENT, `dayStart` int NOT NULL, `dayEnd` int NOT NULL, `isCommonChoice` tinyint NOT NULL, `price` int NOT NULL DEFAULT '200', `pricePerday` int NOT NULL, `discount` int NOT NULL, `currency` varchar(255) NOT NULL, `withDeposit` int NOT NULL DEFAULT '30', `noDeposit` varchar(255) NOT NULL DEFAULT '56', `carId` int NULL, PRIMARY KEY (`id`)) ENGINE=InnoDB");
        
....

这里是 ormconfig.ts 文件

//ormconfig.ts
import  ConnectionOptions  from 'typeorm';

const connectionOptions: ConnectionOptions = 
  type: 'mysql',
  host: 'localhost',
  port: 3306,
  username: 'root',
  password: '',
  database: 'cave',
  synchronize: false, 
  migrationsRun: true,
  logging: ['warn', 'error'],
  entities: ['dist/src/domain/persistence/entities/**/*.js'],
  migrationsTableName: 'migrations',
  migrations: ['src/migrations/*.ts'], 
  subscribers: ['src/subscriber/**/*.ts'],
  cli: 
    entitiesDir: 'src/domain/persistence/entities',
    migrationsDir: 'src/migrations',
    subscribersDir: 'src/subscriber',
  ,
;

export default connectionOptions;

这是我的配置 tsconfig 文件

//tsconfig.json

   "compilerOptions": 
      "lib": [
         "es5",
         "es6",
         "es2020",
         "esnext"
      ],
      "resolveJsonModule": true,
      "module": "commonjs",
      "declaration": true,
      "removeComments": true,
      "emitDecoratorMetadata": true,
      "experimentalDecorators": true,

      "sourceMap": true,
      "outDir": "./dist",
      "baseUrl": "./",
      "esModuleInterop": true
   

我试过了

在 ormconfig.ts 中将 migrations: ['src/migrations/*.ts'], 更改为 [__dirname + 'migrations/*.ts/.js'],，

运行应用时没有错误

，但 migration:run 不起作用 em>..

这里是我如何运行和生成迁移

#generate migration
$ ts-node -r tsconfig-paths/register ./node_modules/typeorm/cli.js --config src/configs/ormconfig.ts migration:generate -n migrationMessageDetail -d src/migrations

#run migration
$ ./node_modules/.bin/ts-node ./node_modules/typeorm/cli.js --config src/configs/ormconfig.ts migration:run

这是我的 json 包

我可以生成并运行迁移，但我不知道为什么会出现此错误SyntaxError: Unexpected token import MigrationInterface, QueryRunner from "typeorm" 请帮忙，非常感谢

【问题讨论】：

你能分享你的 package.json 吗？我想知道你是如何运行迁移命令的。

@uraway 我编辑了我的问题..

【参考方案1】：

您是否尝试过更改此设置：migrations: ['src/migrations/*.ts'], 对此：migrations: ['src/migrations/*.ts,.js'], ?
