问题描述
我有一个版本为8的Angular应用程序。我更新到了9。我解决了所有编译和linter错误，但其中一个给我带来了一些问题：
ERROR in The target entry-point "@angular/cdk/platform" has missing dependencies:
@angular/core
@angular/common
这些是我package.json中的有角度的包：
"@angular/animations": "10.0.12","@angular/cdk": "10.1.3","@angular/common": "10.0.12","@angular/compiler": "10.0.12","@angular/core": "10.0.12","@angular/flex-layout": "10.0.0-beta.32","@angular/forms": "10.0.12","@angular/material": "10.1.3","@angular/platform-browser": "10.0.12","@angular/platform-browser-dynamic": "10.0.12","@angular/router": "10.0.12",我尝试删除node_modules，package-lock.json，重新安装等。
我认为这可能与ivy编译器有关，但它正在编译所有内容（我认为）：
> ngcc --tsconfig './src/tsconfig.app.json' && bash post-install-checks.sh
Compiling @angular/cdk/platform : fesm2015 as esm2015
(and others)
什么会导致这种类型的错误？我想念什么？

更多信息
❯ Undecorated classes with DI migration.
As of Angular 9,it is no longer supported to use Angular DI on a class that does not have an Angular decorator.
Read more about this here: https://v9.angular.io/guide/migration-undecorated-classes
Failed to read JSON file /myDevFolder/dev/node_modules/@angular/material/typings/core/index.Metadata.json
This migration uses the Angular compiler internally and therefore projects that no longer build successfully after the update cannot run the migration. Please ensure there are no AOT compilation errors and rerun the migration. The following project Failed: src/tsconfig.app.json
Error: Path "/../node_modules/@angular/material/typings/core/index.Metadata.json" is invalid.
Could not migrate all undecorated classes that use dependency
injection. Some project targets Could not be analyzed due to
TypeScript program failures.
解决方法
我在这里找到了问题的解决方案：Missing material dependencies after upgrade to Angular 9。也许它可以帮助你。 基本上是：
- 删除 node_modules 文件夹。
- 删除 package-lock.json 文件。
- 运行 npm cache clean --force
- 运行 npm install --save @angular/material @angular/cdk
- 运行 npm install
