Thank you very much!
Can I ask, do you planning to use (in future) composer and CLI version of Joomla CMS?
I'm ready to participate in a future Composer & CLI dependency repository of Joomla.
Thank you again.
Only in very exceptional circumstances should you actually be running a
composer installagainst the 3.x branches. About the only "good" reasons would be to update the dependencies or to run PHPUnit, but since most folks aren't writing tests in the first place the odds of someone actually needing to run the testing framework are pretty close to nil.The Composer error message tells you exactly what is wrong, you're missing PHP extensions on your platform. If you're really adamant about running
composer installfor whatever reason (which is not suggested nor supported for really anything but the two reasons I mentioned before, there's a reason the Composer manifest doesn't ship in release packages), use the--ignore-platform-reqsflag or install the missing PHP extensions.
