Picker 已从 React Native 中删除。现在可以从“@react-native-picker/picker”安装和导入它

Question

请帮忙!!我已经搜索了整个项目，它根本不使用Pricker，但是当我运行 npx react-native run-android 时，它会抛出：

错误不变违规：Picker 已从 React Native 中删除。现在可以从“@react-native-picker/picker”而不是“react-native”安装和导入它。请参阅 https://github.com/react-native-picker/picker错误不变违规：模块 AppRegistry 不是已注册的可调用模块（调用 runApplication）。导致该错误的常见原因是应用程序入口文件路径不正确。当 JS 包损坏或加载 React Native 时出现早期初始化错误时，也可能会发生这种情况。

这个人在下面的链接中面临同样的问题...没有可用的答案...请帮助...提前谢谢您

官方选择器已从 React-Native 中删除。您可以使用社区版。@react-native-community/picker
