在你的android应用级别的gradle文件中，在依赖项中强制react原生版本。

compile ("com.facebook.react:react-native:0.52.0") { force = true }

为我工作

我在使用Expo和iOS模拟器时也遇到了这个问题。对我有用的是擦除硬件中的模拟器>擦除所有内容和设置…

对于那些无法通过关闭和重建来修复的Android开发人员，在模拟器/设备上手动卸载应用程序。

当你试图在不关闭节点服务器的情况下运行前一个应用程序时，有时会发生这种情况，所以尝试重新启动React。要做到这一点，只需运行以下命令:

1. To kill current processes
killall node -9 

2. To Start React  Native
react-native start 

3. Then Run android
react-native run-android

在我的案例中，安装一个新的虚拟设备有所帮助。现在我每个应用程序使用一个设备。

I've never seen this error before, but whenever I can't get Xcode and React-Native to play well together, I do a couple of things. Check what version of Xcode I'm working with. If it needs to be updated, I update it. Then clearing watchman and the cache are the second place I go. I don't use the reset cache command. It always says that I need to verify the cache, so I skip that (you can do it though, I just get confused). I use rm -rf $TMPDIR/react-* to get rid of any cached builds. If that doesn't work, I try to build the app in Xcode, then work my way from there, to build it with react-native run-ios. With this error message, it seems you might start by trying to build it with Xcode. Hope that helps...let me know your progress with it. Good luck! (Also, you could update to RN 0.51 as another attempt to get your versions synced.)
