The error message states that the command “gradlew.bat app:installdebug -preactnativedevserverport=8081” has failed. This command is used to install and run a debug version of the app on a device or emulator using the Preact Native development server on port 8081.
There could be various reasons for this failure. Some possible explanations and examples are:
-
Missing or incorrect gradle wrapper: Make sure that the “gradlew.bat” file is present in the project’s root directory, and it has the necessary permissions to be executed. You can try running the command “gradlew.bat –version” to check if the gradle wrapper is properly configured.
gradlew.bat --version - Build errors: Check if there are any build errors in your project. It’s possible that the app is not building correctly, leading to the failure of the installation command. Check the build logs for any error messages and resolve them accordingly.
-
Incorrect command syntax: Ensure that the command syntax is correct. Double-check if the “app:installdebug” task is available and properly configured in your project’s gradle files. Also, verify if the “preactnativedevserverport” parameter is valid and correctly specified.
./gradlew.bat app:installdebug -preactnativedevserverport=8081 -
Port conflict: The specified port (8081) might already be in use by another application. Try changing the port number to a different value in the command and see if it resolves the issue.
./gradlew.bat app:installdebug -preactnativedevserverport=8082 - Network or device issues: Check if your device or emulator is properly connected to the network. Make sure that the required dependencies and SDKs are installed and up to date. Restarting the device or emulator and trying again might solve the problem.
These are just a few examples of possible causes for the given error. You should carefully analyze the specific error message and the context of your project to identify the root cause and resolve it accordingly.
