8 min read

This error occurs when React Native is unable to find the required native component "RNCPicker" in the UIManager.

To resolve this issue, you can try the following steps:

  1. Ensure that you have installed the necessary dependencies for using the "RNCPicker" component. You might need to install additional packages or libraries.

  2. Make sure that you have properly linked the native module for "RNCPicker" to your React Native project. You can use the command react-native link to automatically link the dependencies, or you can manually link the module if needed.

  3. If you have recently updated your React Native version, there might be some compatibility issues with the native module. In this case, try updating the native module to a compatible version or check if there are any known issues or troubleshooting steps provided by the module's creator.

  4. If you are using a third-party library that depends on the "RNCPicker" component, make sure that the library is properly installed and linked to your project.

  5. Restart your development server and rebuild your project to ensure that all changes are applied correctly.

If none of the above steps solve the issue, you might need to provide more specific details about your project setup, the dependencies you are using, and the steps you have taken so far in order to get further assistance.
