[ERROR] Gulpfile not found: ./gulpfile.js

Or, if you no longer use gulp, you can remove the CLI Gulp Plugin:

    npm uninstall --save-dev --save-exact @ionic/cli-plugin-gulp@latest

Do you use gulp in your project?
When and why did you install @ionic/cli-plugin-gulp?
If you don’t use it, did you try the command the error message told you to?
