尝试更改包中指定的react-native版本。将json(在dependencies - react-native下)改为与错误消息中显示的“Native Version”相同。然后再次运行'npm install'。

这是我对它所做的:

关闭所有终端并再次运行构建。

你可能忘记从另一个项目关闭nodejs终端，而他们碰巧安装了不同的react版本。

因此，从nodejs服务器获取的代码与本机代码冲突。

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。

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.)

尝试重新安装依赖项。这对我很管用

1.) yarn/npm install 2) yarn/npm start——reset-cache

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}
