Flarum requires php 8.0.2 issue

milk

I am trying to install Flarum but it says that it requires php 8.0.2. The problem is, I'm running php 8 and I don't want to update right now. Is there a way to downgrade or reduce the requirement?

I had a look into the vendor folder and the composer file lists the php requirement at >7. What's happening here to require a version of >=8.0.2?

Ignore that (sort of). I've found that it's the composer/platform_check.php file that is requiring php >=8.0.2. Is there a way to reduce this or something? 😂

Gosh, talk about rubber duck debugging.

If anyone else comes across this issue, you can run the following command in terminal and it'll fix it. Obviously it's not advisable to do this, but on a dev site run:

$ composer install --ignore-platform-reqs

Where do you get the error? Is it from Composer output? Flarum should be compatible with anything PHP7.3 or above.

It could be one of Flarum's libraries that is technically compatible with PHP 8 but has a different version for PHP 7.x and its 8.x version could require 8.0.2 due to PHP bugfixes. Composer should list which package is causing the issue when showing the error message.

It might be good to find out which package is causing the issue because it could be a security issue if it's one of the cryptography related packages that throws that error.

In general it's a good idea to always install the latest patch version of any PHP version. Managed hostings usually install those versions automatically.

Hiya, it was in the vendor/composer/platform_check.php file. Although running the above command seems to have removed that file from Composer's vendor system files.

I use Local WP as a development environment (mainly because it's just super quick) and the maximum php version it supports right now is 8.0.0. I could probably update it somehow, but it's just one of those things where it's probably a lot of effort and I could try getting an environment working another way potentially.

I hope that's helpful!

Edit:

I've just checked my php version on my system and funnily enough it says I'm running php 8.1.0. I think it may simply be a case of having to ditch Local WP for this one as I suppose it's doing some weird things in the background and maybe changing the php version.

But yeah, that's weird. It should be working.

I also reinstall the composer packages (to try and undo the ignore platform requirements flag I did prior) and the platform check file is back now.
