How to uninstall and re-install Appium

There are some cases we cannot define the rootcauses for iOS devices' issues. The best practice is to re-install Appium.

1. To know how the Appium was installed, run the command which appium.
   Alternatively, you can navigate to Katalon Studio > Preferences > Preferences > Mobile > Appium Directory to check the current Appium path.
2. Depending on the Appium installation path, you can determine whether Appium was installed with Homebrew or NPM.

   • From NPM: npm uninstall -g appium

   • From Home Brew: brew uninstall appium

3. Reinstall the Appium by running: npm install -g appium
