好吧，试试这个对我有用的：npm install --save-dev @angular-devkit/build-angular
well try this one it works for me:
npm install --save-dev @angular-devkit/build-angular如果安装软件包后错误消息仍然存在，则可能是由于 NPM 设置所致。在最新版本的包管理器中，默认情况下它仅安装项目生产版本所需的包。 “build-angular”包是一个开发依赖项。如果你想让网站正常工作，你必须告诉 NPM 安装开发包，通过在“dev”版本中添加“--only”选项，所以你应该使用这个命令：
npm我--only=devIf the error message persists after installing packages, it may be due to the NPM settings. In recent versions of the package manager, by default it only installs the packages needed for the production version of the project. The "build-angular" package is a development dependency. If you want to make the website work, you have to tell NPM to install the development packages, by adding the "--only" option with the "dev" version so you should use this command instead:
npm i --only=dev谢谢以上各位的解答。
通过遵循以下步骤，包括避免一些错误，我能够使其发挥作用。
安装的软件包在 C 盘而不是我的应用程序文件夹中。
删除了我的旧应用程序并从头开始重新创建它。
然后当我给出“ngserve”时，它运行得很好。
Thank you for above answers.
With below steps followed including avoiding few mistakes, I was able to make it work.
Installed packages in C drive instead of my application folder.
Deleted my old app and recreated it from scratch.
And then when I gave "ng serve" it ran fine.
