Error: command failed: ./gradlew app:installdebug -preactnativedevserverport=8081

To fix the error “command failed: ./gradlew app:installdebug -preactnativedevserverport=8081 ,” you need to perform the following steps:

1. Check the gradle wrapper file:

Make sure you have the gradle wrapper file (gradlew) in the root directory of your project. If it’s missing, you can generate it by running the following command:

gradle wrapper

2. Grant execution permissions:

Ensure that the gradlew file has execution permissions. You can grant the necessary permissions by running:

chmod +x gradlew

3. Clean the project:

Next, clean your project by running the following command:

./gradlew clean

4. Rebuild the project:

5. Install the debug version:

./gradlew app:installDebug

Make sure to replace 8081 with the actual port number you want to use for your preact-native development server.

Here is an example:

./gradlew app:installdebug -preactnativedevserverport=8081
