我有这个问题很长一段时间了，上面的解决方案都没用。我在一个create-react-native-app项目中升级react native，直到我发现不是所有版本的Expo都支持最新的react native。

在文档中找到了这个页面的链接，其中显示了官方支持的React Native, React和Expo的版本组合:

来源:https://github.com/react-community/create-react-native-app/blob/master/VERSIONS.md

编辑app.json和包。Json文件来匹配相应的版本，运行NPM install可以让一切恢复正常。

对我来说，我不得不为react native打开多个node js终端，并且在运行应用程序到我的android设备之前忘记关闭。 我关闭终端，再次运行，它成功加载页面

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.)

我可以通过删除node_modules并再次运行npm install来修复这个问题

在手动更新我的包后，我就遇到了这个问题。 从Expo Go应用程序中删除所有项目并运行Expo update自动为我解决了这个问题。

我更新了react-native版本:0.57.4到0.59.8，我得到以下消息“react-native版本不匹配”

这个解决方案对我来说很有效:

1.- In the folder of the project, update all the code react-native in the Android Studio:

react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res/

2.- Go to Android Studio and FILE->>INVALIDATE CACHES/RESTART
3.- In Android Studio, BUILD->>CLEAN PROJECT
4.- In Android Studio, BUILD->>REBUILD PROJECT
5.- Delete App in simulator or Devices
6.- Run...

希望对大家有所帮助!
