"ExpoNativeModulesProxy“本机模块在更新到sdk34expo后不会通过NativeModules错误导出。

Question

最近，我更新了我的react本地博览应用程序，以使用Expo 34，并且我得到了这个错误：The "ExpoNativeModulesProxy" native module is not exported through NativeModules; verify that expo-react-native-adapter's native code is linked properly。

我已经使用了expo在他们升级到sdk 34文档中建议的他们升级到sdk 34文档，我更新了我的世博-cli，节点版本，并且已经从使用npm转向了纱线，并且无论我尝试什么，都仍然看到这个错误。

我正在使用这个环境：

  Expo CLI 3.0.9 environment info:

为了升级到世博SDK34.0，我使用了他们的释放文档中的世博会说明。我是不是做错了什么事情可能导致了这个问题？如果我签出一个没有新sdk的分支，我不会看到这个错误。

我觉得这是安排一些事情的问题。

您已经将Expo版本从^34.0.1更改为^34.0.4。

但是它没有改变，它在您的package.json文件中。我想我们需要修改这个。

1. rm -rf node_modules
2. 更改"expo": "^34.0.1" => "expo": "^34.0.4"中的package.json
3. yarn install或npm install
4. expo start -c
