问题分析定位
1、网络问题，检查你的代理是否可用
2、npm版本问题
3、node版本问题
解决方法
1、首先检查你的node版本
the node.js version must be v14.19.1 or later and earlier than v17.0.0.the current version is v22.2.0
node.js版本必须为v14.19.1及以上且低于v17.0.0。当前版本是v22.2.0
可以使用下面命令来设置当前node版本，如果没有nvm可以自行搜索下载安装
2、修改地址确定：https://registry.npmjs.org/
3、假如你安装失败了，已经跳过了安装SDK的界面，可以点击import setting来进行重新设置，点击Configure
点击选SDK，然后确定，然后按确定按钮，就会重新跳到设置页面，如下所示：
记得选择node版本为v16.19.1的，如何你没有设置代理，请先设置代理，然后验证代理链接是否是通的，点击Next就可以下载鸿蒙的SDK了。
下载好的效果
结论
尽量在网络好一些的环境去下载，这样不会下载超时，希望这篇文章能帮助到你。
