如何在将文件复制到另一个文件夹后初始化现有Angular 6应用程序?

我已经复制了Angular6应用程序的所有文件和文件夹(除了 节点_模块 文件夹)从另一个磁盘,现在我正在寻找解决方案来初始化它,就像我们在node project中那样。

• 我们有一个节点项目,在复制了除node\u模块之外的所有文件和文件夹之后。
• 我们跑 npm install 它会下载所有引用的依赖项 package.json
• 而不是逃跑 npm start ,这将完美地启动节点应用程序。

我也在努力 角度应用程序 ,确实如此 npm安装 ,后接 ng serve

从中找不到模块“@angular devkit/build angular” “E:\ang\dragAngTodo”。
