问题

我正在尝试从 Angular V9 升级到 V11，但由于以下错误而苦苦挣扎

Namespace node_module/@angular/core/core has no exported member ??FactoryDeclaration
Namespace node_module/@angular/core/core has no exported member ??InjectorDeclaration
Namespace node_module/@angular/core/core has no exported member ??NgModuleDeclaration
Namespace node_module/@angular/core/core has no exported member ???ComponentDeclaration

但我不完全确定这意味着什么以及如何解决它。

我试过的

我看过一个类似的问题：Ng serve throwing @angular/core/core 没有导出成员 'eeFactoryDe​​f'这是我能找到的唯一线索，但它并没有真正帮助我。

我尝试删除我的整个 node_modules 文件夹并使用npm i. 我也试过npm ci了。我也尝试添加

      "@angular/core/*": [
        "./node_modules/@angular/core/*"
      ]

或者

      "@angular/*": [
        "./node_modules/@angular/*"
      ]

到我的tsconfig.json，但这也没有帮助。

我认为是什么问题

我对此一无所知，但我认为我的 NPM 依赖项的路径有问题，因为它引用了@angular/core/core，但我的node_modules.

如果我转到node_modules/@angular/core/core.d.ts我认为是/core/core路径的文件，尽管我不确定这一点，然后我也会在那里看到相同的错误，这让我更加困惑，因为我认为问题出在 Angular 和依赖项之间但不在 Angular 内部。
