Angular 角度10误差“；找不到模块'@角度/核心'；或其相应的类型声明；

我用棱角材料做了一个项目。一切都很好，但我决定将angular和angular material升级到V10，因为我需要一个日期范围选择器，而这只是这些的新版本。 我进行了更新，但当我启动

ng serve-o

时，控制台显示此错误：

ERROR in ../../node_modules/@angular/cdk/overlay/typings/overlay-container.d.ts:8:53 - error TS2307: Cannot find module '@angular/core' or its corresponding type declarations.

8 import { InjectionToken, OnDestroy, Optional } from '@angular/core';
                                                      ~~~~~~~~~~~~~~~
../../node_modules/@angular/cdk/overlay/typings/overlay-container.d.ts:10:25 - error TS2307: Cannot find module '@angular/core' or its corresponding type declarations.

10 import * as ɵngcc0 from '@angular/core';

我尝试清理缓存，然后再次安装@angular/material和@angular/cdk。我尝试了rm-force节点\u模块。。。什么都管用…所以，我需要帮助
