C:\xampp\htdocs\string-desktop>npm start
npm WARN invalid config registry=""
npm WARN invalid config Must be a full url with 'http://'
npm WARN invalid config registry=""
npm WARN invalid config Must be a full url with 'http://'

有人可以帮助我吗？

我相信您使用了错误的命令来运行 Angular 应用程序，您需要使用以下命令来运行 Angular 应用程序。

导航到您的项目目录并运行以下命令。

ng serve

希望这会有所帮助!
