导入角度和剑道的问题

如何解决导入角度和剑道的问题

我一直在收到类似的错误，下面带有红色下划线

import { ViewChild,ViewContainerRef } from '@angular/core';
import { Component,OnInit } from '@angular/core';
Cannot find module '@angular/core'.
Cannot find module 'rxjs'。。。

但是，并非在所有文件中都发生这种情况，例如在50％的文件中会出现错误，但其他50％都可以。我同时删除了两个node_modules文件夹和package-lock.json文件，并在删除它们后运行“ npm install”。但是我仍然遇到所有这些错误。

下面是我的package.json
