未能连接到开发服务器。
确保以下内容：
- 节点服务器正在同一网络上运行且可用-从react-native根目录运行“npm start”
- 在AppDelegate中正确设置了节点服务器URL
- WiFi已启用并连接到与节点服务器相同的网络

这个错误显示在设备模拟器正常工作，但今天出现的问题，没有改变我的React Native代码
I npm在react本地根文件夹启动。当从设备模拟器调用时，Metro Bundler停留在99.4%
我的React原生版本是0.61.2
我尝试解决它的许多解决方案从谷歌，但它还没有工作。请。建议我

我可以解决这个。原因从有下面的代码在一些文件在我的项目
当我摆脱它，我的项目又回来工作了
