Unable to install extensions because my PHP version is too high?

tobin

Every time I try to install a package, (and it does this for every package, I've even tried the newest ones available) I get the message:

Your requirements could not be resolved to an installable set of packages.

The problems that it gives are these:

Problem 1 - laminas/laminas-diactoros 2.17.0 requires php ^7.4 || ~8.0.0 || ~8.1.0 -> your php version (8.2.10) does not satisfy that requirement. - flarum/core v1.8.2 requires laminas/laminas-diactoros ^2.4.1 -> satisfiable by laminas/laminas-diactoros[2.17.0]. - flarum/core is locked to version v1.8.2 and an update of this package was not requested.

I've also tried running composer with a versions constraint, but it still has the same error. What can I do about this? I also install Flarum using softaculous if that makes a difference.

It seems to be some kind of caching issue as it isn't picking up on more recent package versions of dependencies from packagist.com.

laminas/laminas-diactoros has more recent versions compatible with php-8.2, so technically it should download that. I would maybe try clearing composer cache and updating composer CLI

composer clear-cache
composer self-update

SychO Thanks so much for the help! I can't update composer 'cause of my hosting setup, but clearing the cache was all it took to get extensions installing.
But unfortunately the extensions aren't working; I can't find any sign of the installs outside of the terminal (Even after clearing composer & flarum caches).

It does give a warning, but is this related?

Package swiftmailer/swiftmailer is abandoned, you should avoid using it. Use symfony/mailer instead.

Does it take time for the packages to fully install? Is there some other cache I need to clear?

tobin the swiftmailer warning can be ignored. It's a warning for Flarum developers.

Once the Composer commands completes, everything should be done, there is no background process. But make sure the process finished without any error.

Make sure you run the commands in the correct directory.

clarkwinkelmann For a while the commands would complete, but nothing would show up on the website. I tried again a bit later and started getting the original error again. Last time I just needed to clear composer's cache, but this time it still isn't working.

Right now I'm trying to get the (Hostgator) server owners to upgrade Composer, since I can't.

tobin

Hostgator won't let me update Composer, and I'm guessing that's the issue, so I guess that's it. Thanks for the help guys!

tobin I am rereading your first message and from what I can see it doesn't relate to composer at all. Have you tried running the composer command with -W? Because that allows composer to download packages compatible with your php version.

I'm also missing the output of composer --version to see what version you are on (but I highly doubt that is the underlying problem).
