On a fresh flow install, that is after copying my existing site and launching "composer install" with sucess, when I execute the "flow" command, I obtain the following error:
PHP Fatal error: Uncaught exception 'TYPO3\Flow\Package\Exception\InvalidPackag
eStateException' with message 'Package "doctrine.common" is already registered a

I'm really out of clue here on what to do or what's causing this issue. Nothing was found on the web either.
I had to delete the PackageStates.php file and then everything worked fine.
