【问题描述】：
我下载了一个 Angular 12 项目，并尝试使用 Angular 13（最新版本）运行它。因此，当我尝试运行它时，我遇到了问题。即使我尝试使用 npm install，也会抛出一些依赖问题
使用ng serve运行时抛出的错误：
An unhandled exception occurred: Cannot find module '@angular-devkit/build-angular/package.json'
Require stack:

See "/private/var/folders/w0/wfq3__js19g4lbf33bpkwbrm0000gp/T/ng-hQcZ24/angular-errors.log" for further details.
我尝试使用 npm 安装，但也抛出了一些其他错误：

由于某些原因，您的某些库的版本不兼容，请尝试将
rxjs降级到 6.6.7 -
请分享您的
package.json。
