What is @react-native-community/cli-doctor?
The @react-native-community/cli-doctor package is a part of the React Native CLI which provides a set of utilities to check and diagnose issues with your React Native environment setup. It helps in identifying problems with the development environment that could prevent React Native applications from compiling and running correctly. It automatically scans your system for common issues and suggests fixes for identified problems.
Environment Checks
This command scans your development environment for common issues. It checks software versions (like Node, Java, Watchman, etc.), iOS and Android development environment setup, and provides detailed reports. If issues are found, it suggests fixes or improvements.
npx @react-native-community/cli doctor
Issue Diagnosis
In addition to identifying issues, the CLI doctor can automatically attempt to fix certain problems. This feature is particularly useful for quickly resolving common configuration errors without manual intervention.
npx @react-native-community/cli doctor --fix
