我创建了一个 jhipster 应用程序，使用 Angular 作为前端 ui 框架。下面给出了jhipster和node版本。
jhipster: 7.9.3,
npm: '9.6.5',
node: '18.16.0',
现在我想添加 matrerial-ui 来创建响应式应用程序。为此，我运行了以下命令。
添加@Angular/Material
但是我收到以下错误日志。

我也尝试了“ng add @angular/material --legacy-peer-deps”。但它也不起作用。
我尝试升级 Angular cli 和 core。那些时候我得到了以下错误。
>ng update @angular/core
The installed Angular CLI version is outdated.
Installing a temporary Angular CLI versioned 16.1.1 to perform the update.

Updating multiple major versions of '@angular/core' at once is not supported. Please migrate each major version individually.
Run 'ng update @angular/core@15' in your workspace directory to update to latest '15.x' version of '@angular/core'.
For more information about the update process, see https://update.angular.io/?v=14.0-15.0
在jhipster项目中升级Angular和安装material-ui的正确方法是什么？
在手动一一升级每个依赖项后，我能够安装材质 UI。我使用了以下命令，
ng update @angular/cli@15 --force
ng update @angular/cli@16 --force
ng update @angular-builders/custom-webpack
ng update @angular-builders/jest
ng update @fortawesome/angular-fontawesome
ng update @ng-bootstrap/ng-bootstrap
ng update jest-preset-angular
ng update ngx-infinite-scroll
ng update ngx-webstorage
ng update ts-jest
（注意：每次升级后都会要求您提交更改。）
如果有比这更简单的方法，请分享。
升级 Angular 后，我在导入 scss 样式表时遇到问题。我更改了路径并使用样式表的相对路径。
这个问题解释了问题并提供了答案。
同样的问题：任何更简单的解决方案：@matt-raible？谢谢
