Hi Alex T⚜️,

I want to thank you for taking the time to answer my question. I got it to work now!

First of all, I have uninstalled the Phing I've installed using the pear command.

Then I run the command you provided but i slightly changed it because the file I downloaded from https://www.phing.info/  was phing-latest.phar

So the final command I run was:

php phing-latest.phar package_all_langs

and it works perfectly. Once again, thanks for the support!
