dart
Failed to obtain the SDK information. The SDK will not be downloaded. You can download the SDK later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。
