[Support] 运行test时出现错误 Cannot find module 'typeorm'

[fenglekai]

Describe the problem（描述问题）

在我引入Typeorm后测试用例midway-bin test -f test/db.test.ts无法运行，有什么办法可以解决吗？

import { createApp, close } from '@midwayjs/mock';
import { Framework } from '@midwayjs/koa';
import {GoodsService} from '../src/service/goods.service';

describe.only('test/db.test.ts', () => {

  it.only('db test', async () => {
    // create app
    const app = await createApp<Framework>();

    const service = await app.getApplicationContext().getAsync<GoodsService>(GoodsService);
    const result = await service.InsertGoods();
    console.log(result);
    
    // use expect by jest
    expect(result).toReturn();

    // close app
    await close(app);
  });

});

> midway-bin test -f test/db.test.ts

你只是安装了 typeorm 组件吧，typeorm 模块需要额外安装。

我都已导入，顺便说一下我是pnpm dev可以正常启动的并调试，但是在pnpm test无法运行。

  "dependencies": {
    "@midwayjs/bootstrap": "^3.12.0",
    "@midwayjs/core": "^3.12.0",

    "@midwayjs/info": "^3.12.0",

  },

我找到问题了，因为我使用的是pnpm安装的依赖，在一些目录层级下出现问题。我改用npm去安装依赖后解决

[czy88840616]

是因为pnpm的特殊目录结构造成的？

[fenglekai]

我想是的，当我看到node_modules/.pnpm/@[email protected]/node_modules/@midwayjs/typeorm/dist/decorator.js这样的目录的时候。
