Jestjs 角离子存储的Jest测试失败

嗨，我用的是angular 11和ionic 5

对于离子存储，我使用@ionic/storage:^3.0.6模块

在jest单元测试期间，我得到

无法从中找到模块'@ionic/storage' 'node_modules/@ionic/storage angular/bundles/ionic storage angular.umd.js'

@ionic/storage angular是我模拟的其中一个服务中的依赖项

jest.confi.js已经

transformIgnorePatterns: [
    './node_modules/(?!@ionic|ngx-socket-io/|!@ionic/storage-angular)'
]

模拟服务的规范文件

let storeServiceStub={
  get:jest.fn().mockResolvedValue({})
};

await TestBed.configureTestingModule({
      declarations: [ DataSyncComponent ],
      providers:[
        { provide: StoreService, useValue: storeServiceStub },
      ]
})
.compileComponents();

@ionic/storage angular是一种商店服务，我正在用存根取代它

测试env-to-repo错误 package.json

dependencies:{
  ...
  "@ionic/storage-angular": "^3.0.6",
  ...
}
devDependencies:{
  ...
  "jest": "^27.0.3",
  "jest-preset-angular": "^9.0.1",
  "@types/jest": "^26.0.23",
  ...

}

os osx 11.2.2

在jest.config.js中为@ionic/storage提供jest模块映射，如下所示：

    ...,
    transformIgnorePatterns: [
      './node_modules/(?!@ionic|ngx-socket-io/|!@ionic/storage-angular)'
    ],
    "moduleNameMapper": {
      "@ionic/storage": "<rootDir>/node_modules/@ionic/storage/dist/esm"
    }

。。。，
转换信号模式：[
“./节点_模块/（？！@ionic | ngx插槽io/|！@ionic/storage angular）”
],
“moduleNameMapper”：{
“@ionic/storage”：“/node_模块/@ionic/storage/dist/esm”
}

您可以找到有关moduleNameMapper的更多信息。

我尝试了这个方法，但得到的结果是`SyntaxError:无法在localforge的模块外使用导入语句，localforge是@ionic/storage的依赖项`
