Issues with phalcon dev tools

[krishnan-ubuntu]

I'm new to phalcon and I'm having issues with phalcon dev tool commands.

When I type phalcon serve I get the following error.

Phalcon DevTools (4.1.2)

PHP Fatal error:  Class 'Phalcon\Mvc\User\Component' not found in /opt/phalcon-devtools/scripts/Phalcon/Utils/SystemInfo.php on line 36

I looked for answers but couldn't find much. Thanks in advance.

Back in v3, components would extend Phalcon\Mvc\User\Component. In v4, that has been changed to \Phalcon\Di\Injectable - which you can see here: https://github.com/phalcon/phalcon-devtools/blob/ad7a6eb1a109f62ff07d6eb5abf6c370fdbeaa2b/src/Utils/SystemInfo.php

This error is seeming to say that /opt/phalcon-devtools/scripts/Phalcon/Utils/SystemInfo.php is a version of the file from 3.4, since it's trying to extend \Phalcon\Mvc\User\Component. My guess is the version of the devtools you're using is 4.1.2, and the version of Phalcon you have installed is 4.1.2, but the scripts that got installed into /opt/phalcon-devtools/scripts/ are still the 3.4 version.

I'd try removing what's there and reinstalling.

composer global remove phalcon/devtools
composer global require phalcon/devtools
