我对 Angular 和网络编程完全陌生。正如我在教程 [链接]中看到的那样，尝试在 github/angular 克隆快速入门并使用“npm start”启动 lite-server，但它不起作用。我应该更改系统的变量或类似的东西吗？如果有帮助，这是 npm 的日志：

23 error Make sure you have the latest version of node.js and npm installed.
23 error If you do, this is most likely a problem with the angular-quickstart package,
23 error not with npm itself.
23 error Tell the author that this fails on your system:
23 error tsc && concurrently "tsc -w" "lite-server"
23 error You can get information on how to open an issue for this project with:
23 error npm bugs angular-quickstart
23 error Or if that isn't available, you can get their info via:
23 error npm owner ls angular-quickstart
23 error There is likely additional logging output above.
