编辑您的包。Json为你的javascript版本

"react-native": "^0.50.1",

后运行

npm install

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!

在我的情况下，我的android物理设备没有连接到运行在我的开发机器上的js服务器。所以我必须手动设置调试服务器主机和端口在我的android设备。

Opene管理扫描/ android / app / build.gradle

试一试:

编译("com.facebook.react:react-native:0.51.0") {force = true}

而不是 编译"com.facebook.react:react-native:0.51.0" {force = true}

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.)
