your environment meets the requirements?

Apache (with mod_rewrite enabled) or Nginx
PHP 7.3+ with the following extensions: curl, dom, gd, json, mbstring, openssl, pdo_mysql, tokenizer, zip
MySQL 5.6+ or MariaDB 10.0.5+
SSH (command-line) access to run Composer

seems that you don't have some php ext

Leonardo0801

Justoverclock How can I check this?

Justoverclock

Leonardo0801 what is your hosting?

Leonardo0801

Justoverclock Contabo, I have Ubuntu.

I solved that problem but now when I try to connect I get "Nginx Error 403 Forbidden".

Leonardo0801

Error changed: "Composer detected issues in your platform: Your Composer dependencies require a PHP version ">= 7.4.0"."

Justoverclock

Leonardo0801 so you need to upgrade your php to that version

Leonardo0801

Justoverclock I have PHP to a version higher than 8.0 so that's not the problem

Leonardo0801

Leonardo0801 I tried updating the php dependencies but nothing. I'm stuck here for more than 3 hours...

The web and command line PHP versions can be different on some hosting. If the hosting is managed, there's usually a PHP version choice somewhere that applies globally to the command line, which can be different from each individual site PHP version. Ideally both should be identical to use Flarum.

If the hosting isn't managed and there are multiple PHP versions, there's a command to update which one the php alias points to, though I don't remember it. You can also manually call the PHP executable you need if the default cannot be changed, for example php8.0 composer install [...]. The exact name of the PHP executable for each version might vary depending on the operating system.

Leonardo0801

clarkwinkelmann I installed the composer but it says that it needs php phar. How can I fix this?

Leonardo0801

clarkwinkelmann And now when trying to install composer I get this error:
Some settings on your machine make Composer unable to work properly.
Make sure that you fix the issues listed below and run this script again:

The phar extension is missing.
Install it or recompile php without --disable-phar

The iconv OR mbstring extension is required and both are missing.
Install either of them or recompile php without --disable-iconv

luceos

The original error spoke of a missing PHP extension called dom. This was while composer was executed with PHP 7.4. You can install that extension if the same error is still being shown, otherwise we'd need to know the latest error, the command you used and the PHP version the command was executes with (php -V).

Leonardo0801

I used this command:
curl -sS https://getcomposer.org/installer | sudo php -- --install-dir=/usr/local/bin --filename=composer

This is the php version:
PHP 8.0.11 (cli) (built: Sep 23 2021 21:26:24) ( NTS )
Copyright (c) The PHP Group
Zend Engine v4.0.11, Copyright (c) Zend Technologies

Where are the latest errors?

Leonardo0801 PHP 8.0.11 (cli) (built: Sep 23 2021 21:26:24) ( NTS )

Leonardo0801 you are on php 8.0, so you would need to install dom with sudo apt install php8.0-dom.

Leonardo0801

And when I try to see extentions installed (with php -m) that extention doesn't appears. (Sorry for my bad english)
luceos please help

I have the same error

luceos

Leonardo0801 looks like php is compiled without phar support, is this shared hosting? If so you'll need to contact your hosting provider to ask them how to run composer.

Leonardo0801

luceos No it's a VPS. When I try to install extentions they don't appartamento in php-m

I don't know, how can I compile php with this phar support?
