学习角度
尝试执行those simple steps生成新项目，但是当我尝试启动ng-serve时遇到了以下错误：
Could not find module "@angular-devkit/build-angular" from "C:\\Users\\lingar\\AngularProjects2\\project1".
Error: Could not find module "@angular-devkit/build-angular" from "C:\\Users\\lingar\\AngularProjects2\\project1".

尝试了许多those solutions都没有成功。
有人有想法吗？
编辑：解决了！
感谢@Seth McClaine在我去the Technical Specifications of this module @angular-devkit/build-angular的评论中的回答，
从那里，我接受了install命令并在cmd上运行它：
npm i @angular-devkit/build-angular，从那时开始运作良好。
顺便说一句-在解决方案之前，我有一个奇怪的问题，那就是只有在root用户目录中，它才能很好地工作。
@angular-devkit/build-angular specification
最佳答案
尝试这个。
npm i --only=dev
在npm之后安装并运行您的项目
关于node.js - 用ng serve找不到模块“@ angular-devkit/build-angular”，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/52843908/
