React native NavigationContainer中的反应本机错误

由于我是

react native

新手，所以我正在尝试在

react native

中构建一个可以导航的简单应用程序

index.js

在我的

app/build.gradle

中，我添加了以下两个：

implementation 'androidx.appcompat:appcompat:1.1.0-rc01'
implementation 'androidx.swiperefreshlayout:swiperefreshlayout:1.1.0-alpha02'

---

重新启动并使缓存无效。

错误是因为

AppRegistry.registerComponent

接受返回组件的函数，但您正在传递组件

改变

AppRegistry.registerComponent（appName，MyStack）；

到

您还从错误的位置导入了

createStackNavigator

。您需要像这样导入它：

从'@react navigation/stack'导入{createStackNavigator}；

您错误地导入了createStackNavigator，您应该从'@react navigation/stack'导入{createStackNavigator}。首先看看这是否有帮助。您导入createStackNavigator不正确，您应该从'@react navigation/stack'导入{createStackNavigator}。先看看这是否有帮助。
