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

Question

PLEASE HELP:!I have search the entire project which DOES NOT use Pricker at all but when I run npx react-native run-android it throws out :

ERROR Invariant Violation: Picker has been removed from React Native. It can now be installed and imported from '@react-native-picker/picker' instead of 'react-native'. See https://github.com/react-native-picker/picker ERROR Invariant Violation: Module AppRegistry is not a registered callable module (calling runApplication). A frequent cause of the error is that the application entry file path is incorrect. This can also happen when the JS bundle is corrupt or there is an early initialization error when loading React Native.

Same problem faced by this guy at the below link...No answer available... Please help...Thank you in advance

Answer 1

Officially picker has been removed from react-native. You can use the community edition. @react-native-community/picker

Answer 2

Delete node modules folder then run yarn install at the terminal in your projects directory.

Then try to run the app again.

I am not sure this will help but since it says This can also happen when the JS bundle is corrupt or there is an early initialization error when loading React Native. it might be worth trying.

Answer 3

1. Install @react-native-picker/picker
2. Upgrade "native-base": "2.15.2"

Answer 4

In my case, tcomb-form-native caused this error because it has not been updated for years. I hope this PR will be merged soon. https://github.com/gcanti/tcomb-form-native/pull/605
