React Native – error: “unknown command” run-android
The “Unknown Command” error in React Native can occur when you run the run-android command in your terminal or command prompt. Here are a few possible solutions to fix this error:
- Make sure you are in the correct directory: The
run-androidcommand should be run from the root directory of your React Native project. Double-check that you are in the correct directory before running the command. - Make sure you have set up the Android environment: To run the
run-androidcommand, you need to have the Android environment set up on your computer. Make sure you have installed the necessary software, such as the Android SDK and JDK, and that the environment variables are set correctly. You can find detailed instructions on how to set up the Android environment in the React Native documentation. - Try using the “gradlew” script: Instead of running
run-android, try running the./gradlewscript in theandroid/directory of your React Native project. This script should automatically build and run your app on an Android emulator or device. - Try using a different terminal or command prompt: Sometimes, the terminal or command prompt you are using can cause issues with React Native. Try using a different terminal or command prompt to see if that fixes the issue.
