angular - 将文件复制到另一个文件夹后如何初始化现有的 Angular 6 应用程序？

Question

我已经从另一个磁盘复制了我的 Angular 6 应用程序的所有文件和文件夹（node_modules文件夹除外），现在我正在寻找解决方案来初始化它，就像我们在节点项目中所做的那样。

考虑一下（node.js 示例）：

• 在复制除 node_modules 之外的所有文件和文件夹后，我们有一个 node 项目。
• 我们运行npm install它下载所有引用的依赖项package.json
• 比 run npm start，这会完美地启动节点应用程序。

我正在尝试对Angular 应用程序进行相同的操作，但npm install随后ng serve出现如下错误：

无法从“E:\ang\dragAngTodo”中找到模块“@angular-devkit/build-angular”。
