Question

我收到此错误找不到模块'@ angular / core'。然后搜索SO寻求帮助，虽然有问题，但没有任何帮助。

这与错误的版本导入有关吗？在命令窗口中运行

L：\ NetProject \ BooksProject \ BooksProject \ ClientApp> ng构建

并得到相同的错误

BooksProject> 
BooksProject> fail: Microsoft.AspNetCore.SpaServices[0]
BooksProject>       ERROR in ../../../node_modules/@angular/cdk/bidi/typings/dir-document-token.d.ts(8,32): error TS2307: Cannot find module '@angular/core'.

BooksProject>       ../../../node_modules/@angular/cdk/text-field/typings/autosize.d.ts(8,71): error TS2307: Cannot find module '@angular/core'.
BooksProject>

如果我调试该应用程序时，仅显示文字显示在get浏览器窗口中， “无法获取/”

我删除了node_modules文件夹并进行了npm安装

我在@HariniP建议后运行命令，谢谢！

npm我@ angular / core

这是输出，我需要修复所有这些警告吗？
