Installation issue: PHP version ">= 8.1.0" required

robert-winkler

Dear Flarum experts,

Hi, I just installed Flarum on a VPServer.

The system is Ubuntu 20.04 LTS; apache2.

in the newly created directory /var/www/html/labi-list and run
composer create-project flarum/flarum .
There was a warning

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

anything else went smooth.

I changed the subdirectory owner: chown -Rvf www-data:www-data labi-list.

However, when I go to my domain.org/labi-list, I only get a directory/file listing.

changing to /public informs:

Composer detected issues in your platform: Your Composer dependencies require a PHP version ">= 8.1.0".

Any idea what is missing?

Thanks, Robert

Try run composer update again

I honestly think the error is showing when browsing to the page using a web browser. This implies that the website runs on a different version of php than the cli version (8.1) which you used to install Flarum with.

robert-winkler

Thanks for your ideas!

composer update didn't help.

I did not understand the comment about the web browser. Isn't it the normal way to access the platform?

Could this be problem of access rights (although I try to avoid a chmod -Rvf 777 * on my web server ;-))?

robert-winkler where do you see the error? In your browser or on the commandline?

robert-winkler

The error appears in the browser.

robert-winkler

It seems that I need to run php flarum install..

Check your managed hosting admin panel. You can generally choose one PHP version for each of your websites, and one for the "command line".

From your error it seems like the "command line" version was different from your website version, so Composer downloaded a version of Flarum's dependencies that doesn't actually work on your website PHP version.

Make sure the same version is used for both places, and restart the installation (create-project) after fixing it.

To see the current versions if your managed hosting doesn't show them, php -v via SSH will show you the command line version, and to see the website version you can create a PHP file that calls phpinfo();. Accessing that file via the browser will show various informations about PHP including the web version.

robert-winkler

Indeed, this might be the problem!!!
I created a file info.php
<?php phpinfo();
chown www-data:www-data info.php; chmod 755 info.php
and it reported PHP version 7.3.
php -v on the server reports 8.1.
o.k. I will purge 8.1 (since some programs still need 7) and re-install everything with version 7.4.

robert-winkler

OK. Now I have the same PHP version for the CLI and web version: 7.4.3

I re-installed flarum, changed the owner of the install to www-data and the permissions to 755.
As well, I created and enabled an apache2 .conf
according to https://www.howtoforge.com/tutorial/ubuntu-flarum/

I created a subdomain linking to the installation directory:
labi-list.meteomex.com
which is also set as in config.php
'url' => 'http://labi-list.meteomex.com',

Anyway, the going to http://labi-list.meteomex.com just opens the listing again.
in /public, I get:

The page you requested could not be found.

Return to Labi-List

Any idea?
