当存在相冲突的软件包版本时，我的Angular项目无法编译（ng build --prod）。我们正在使用内部构建并发布到本地NPM存储库的一组组件。

当项目中使用冲突版本时，这些组件将安装在从属组件内的node_modules中。例如，

in application package.json
dependencies: {
   "A": "1.0.0","B": "1.0.0"
   ...
}

A's package.json (in library)
{
   version: "1.0.0",dependencies: {
      "X": "1.0.0"
   }
}

B's package.json (in library)
{
   version: "1.0.0",dependencies: {
      "X": "2.0.0"
   }
}

X's package.json (in library)
{
   version: "1.0.0",dependencies: {
      "Y": "1.0.0"
   }
}

{
   version: "2.0.0",dependencies: {
      "Y": "2.0.0"
   }
}

当我在应用程序中安装软件包（npm install）时，软件包的安装如下，

/
   node_modules/
      A@1.0.0
      X@1.0.0
      Y@1.0.0
      B@1.0.0
         node_modules
            X@2.0.0
            Y@2.0.0

据我所知，这是NPM方面的预期行为。

但是，当我尝试使用ng build --prod构建应用程序时，出现以下错误。

Illegal state: Could not load the summary for directive MenuComponent in E:/projects/ntc/node_modules/@tc/profile/node_modules/@tc/menu/menu.component.d.ts

（在这种情况下，“菜单”就像“ Y”一样，它是第二级依赖项）

该库项目遵循旧的Angular Material组件库结构，并使用 ngc 编译器（ngc -p ./src/lib/tsconfig-ngc.json）来构建所有组件。

tsconfig-ngc.json
{
  "$schema": "http://json.schemastore.org/tsconfig","angularCompilerOptions": {
    "debug": true,"fullTemplateTypeCheck": true,"genDir": "./../dist/@tc","skipTemplateCodegen": true,"strictMetadataEmit": true,"enableResourceInlining": true
  },"compilerOptions": {
    "baseUrl": ".","declaration": true,"experimentalDecorators": true,"inlinesources": true,"lib": [
      "es6","dom"
    ],"module": "es2015","moduleResolution": "node","outDir": "./../../dist/@tc","paths": {
      "@tc/*": [
        "./*"
      ]
    },"rootDir": ".","sourceMap": true,"stripInternal": true,"target": "es5","typeRoots": [
      "../node_modules/@types"
    ],"types": []
  },"include": [
    "**/*.ts"
  ],"exclude": [
    "**/*.spec.ts"
  ]
}

我有什么想念的吗？此问题的根本原因是什么？
