当使用模块联合体系结构导入角应用程序时，必须从注入上下文调用"inject()“

Question

我试图按照下面的示例webpack5模块联合在有角模块联合中实现微前端概念，但是我面临着这个错误。

​

我尝试了这个答案inject()必须从注入上下文中调用中提供的解决方案，但是它没有起作用。

目前，我正在使用角版本11在这两个应用程序。

正在导入的应用程序的package.json (子)

Answer 1

面对同样的问题，在计算出@angular/core和@angular/common (可能还有@ngx-translate/core)之后，错误得到了解决，并且必须在您的webpack配置中使用"singleton: true“标志共享并加载一次。

Answer 2

当您的任何子依赖关系没有满足角核心或角公共时，就可能发生这种情况。尝试检查控制台/终端以获得更多信息。在我的例子中，我在子组件中安装了高图表，并通过父组件获得了角核10.0.0上的对等依赖。一旦我更新了版本，错误就消失了。

Answer 3

在我的例子中，我使用的是来自requiredVersion: 'auto' and sharedMappings.getDescriptors()包的@angular-architects/module-federation。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' },
