**解决措施**

1.  尝试清除本机DevEco Studio缓存文件后重启，缓存目录：
    
    Windows:C:\\Users\\xxx\\AppData\\Local\\Huawei\\DevEcoStudioX.X\\caches
    
    Mac：~/Library/Caches/Huawei/DevEcoStudioX.X/caches
    
2.  尝试修改本机网络环境后进行重试，例如：[配置Proxy代理](https://developer.huawei.com/consumer/cn/doc/harmonyos-guides/ide-environment-config#section10369436568)、连接手机热点、关闭VPN。
3.  请检测您的网络并确认您当前电脑环境或华为账号是否在[模拟器支持的国家/地区](https://developer.huawei.com/consumer/cn/doc/harmonyos-guides/ide-emulator-devicetype)内。
