npm' 不是内部或外部命令，也不是 Visual Studio 中的可运行程序或批处理文件

Question

在此处输入图像描述我无法使用ng serve在 Visual Studio 中构建 angular 项目，但我可以使用node.js 命令提示符来完成，请给我解决方案

Answer 1

Aside from the solutions suggested in the links which are posted in the comments, you can also try the below command to update the PATH,

set PATH=%PATH%;C:\Users\YOUR_USER_NAME_OR_LOGIN\AppData\Roaming\npm;

Once executed, try re-running your ng serve command again.

Hope this helps!

Answer 2

Install Angular cli globally using this command.

$ npm install -g @angular/cli

the -g switch installs angular cli(or any npm package globally on your system).
