我正在尝试按照这个示例Module federation with angular 使用webpack5 模块联合以 Angular 实现微前端概念，但我遇到了这个错误错误：未捕获（在承诺中）：错误：必须从注入上下文调用注入（）

我尝试了这个答案中提供的解决方案inject() must be called from an injection context但它不起作用。

目前我在两个应用程序中都使用 Angular 版本 11。

正在导入的应用的 package.json（子）

就我而言，我使用的是requiredVersion: 'auto' and sharedMappings.getDescriptors()from @angular-architects/module-federationpackage。所以我指定了确切的版本。

"@angular/core": { singleton: false, strictVersion: true, requiredVersion: '12.2.15' },
"@angular/common": { singleton: false, strictVersion: true, requiredVersion: '12.2.15' },
"@angular/router": { singleton: false, strictVersion: true, requiredVersion: '12.2.15' },

当您的任何孩子依赖没有遇到角核心或角共同时，这可能会发生。尝试检查控制台/终端以获取更多信息。在我的情况下，例如：highchart 我已经安装在子组件中，并获得对 angular core 10.0.0 与父组件的对等依赖。一旦我更新了版本，错误就消失了。

面对同样的问题，在弄清楚@angular/core并且@angular/common（并且可能@ngx-translate/core）必须在两个 webpack 配置中使用“singleton: true”标志共享和加载一次之后，错误就解决了。
