如何在Angular 8 ASP.NET中解决此生成错误

我发现此错误，无法找到模块'@angular/core'。在这方面寻求帮助，虽然有问题，但对我毫无帮助

这是否与错误的版本导入有关？在我运行的命令窗口中

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

并得到相同的错误

BooksProject> 
BooksProject> fail: Microsoft.AspNetCore.SpaServices[0]

如果我在“获取浏览器”窗口中调试应用程序时只显示文本， “无法获取/”

我删除了node_modules文件夹并安装了npm

我根据@HariniP的建议运行命令，谢谢

角向/核心处的npm i

这是输出，我需要修复所有这些警告吗

使用命令安装angular

npm i@angular/core

在您的项目目录中。

我通过添加以下内容修复了我的问题：

True
True您在那之后尝试过构建吗？我从VS中清理并重建项目，然后得到构建：1成功，0失败，0最新，0跳过-没有错误，但从windows命令提示符我得到这个初始错误，当我调试runOk时，VS Build成功，您能在浏览器中查看应用程序吗？浏览器仅显示“无法获取/”，它不会在Startup.cs中加载我的组件。我可以在ConfigureServices中放置一个断点，并且程序会停止正常运行。加载大约60秒后打开浏览器时，会出现此初始错误，浏览器中唯一可见的错误是左上角的“无法获取/”
