Node.js 角度：意外值中的错误'；CdkScrollableModule

我做了npm更新，突然发现自己的应用程序停止工作了

我遇到了以下问题：

ERROR in Unexpected value 'CdkScrollableModule in /Users/***/dev/FEprojects/GsmMusicApp/node_modules/@angular/cdk/scrolling/index.d.ts' imported by the module 'MatSidenavModule in /Users/***/dev/FEprojects/GsmMusicApp/node_modules/@angular/material/sidenav/index.d.ts'. Please add a @NgModule annotation.
Can't export value CdkScrollableModule in /Users/***/dev/FEprojects/GsmMusicApp/node_modules/@angular/cdk/scrolling/index.d.ts from MatSidenavModule in /Users/***/dev/FEprojects/GsmMusicApp/node_modules/@angular/material/sidenav/index.d.ts as it was neither declared nor imported!

我曾尝试在AppModule中添加CdkScrollableModule，但没有任何效果

我如何解决这个问题

问候,

请尝试完全删除node_modules目录并再次运行“npm install”。哪一个？node_modules作为多个目录存在，如果我删除最顶层的一个，npm安装将不再工作。我指的是项目级的node_modules目录，因此位于package.json或angular.json（顶层）的位置旁边。为什么npm安装不再工作？您是否在正确的目录中执行了该命令？好的，现在我找到了正确的文件夹，并将其删除，npm安装工作正常，但ng serve仍报告相同的问题。npm安装报告如下：（由于coments中的字符限制，必须使用pastebin）好的，我明白了，必须安装“npm安装”警告的那些版本，它现在可以工作了。但是我不知道如何处理关于@ngtools的警告/webpack@10.0.8，它需要typescript 3.9>但angular 9需要typescript
