当TypeScript类型定义不匹配时，我得到了这个类。

例如，在依赖项中react-native的值为0.61.5，在devDependencies中@types/react-native的值为0.60.0。

当我更新devDependencies时，它就工作了。不需要重启任何东西。

我正在使用物理设备，在我的情况下，这解决了问题:

卸载应用程序 Lsof -i:8081 kill -9 PID 重新构建应用程序(react-native run-android或react-native run-ios)

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}

裁判:链接

我已经尝试了上面的解决方案，但将此添加到AndroidManifest.xml似乎可以修复它。

  android:usesCleartextTraffic="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.)

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
