Okay, I have solved the first problem, but now I have another one....
Your requirements could not be resolved to an installable set of packages.
Problem 1
- Root composer.json requires flarum/core ^1.8 -> satisfiable by flarum/core[v1.8.0, ..., v1.8.9].
- flarum/core[v1.8.0, ..., v1.8.3] require s9e/text-formatter ^2.3.6 -> satisfiable by s9e/text-formatter[2.3.6, ..., 2.18.0].
- flarum/core[v1.8.4, ..., v1.8.9] require s9e/text-formatter >=2.3.6 <2.15 -> satisfiable by s9e/text-formatter[2.3.6, ..., 2.14.3].
- s9e/text-formatter[2.3.6, ..., 2.18.0] require ext-dom * -> it is missing from your system. Install or enable PHP's dom extension.
To enable extensions, verify that they are enabled in your .ini files:
- /etc/php/8.3/cli/php.ini
- /etc/php/8.3/cli/conf.d/10-opcache.ini
- /etc/php/8.3/cli/conf.d/10-pdo.ini
- /etc/php/8.3/cli/conf.d/20-calendar.ini
- /etc/php/8.3/cli/conf.d/20-ctype.ini
- /etc/php/8.3/cli/conf.d/20-curl.ini
- /etc/php/8.3/cli/conf.d/20-exif.ini
- /etc/php/8.3/cli/conf.d/20-ffi.ini
- /etc/php/8.3/cli/conf.d/20-fileinfo.ini
- /etc/php/8.3/cli/conf.d/20-ftp.ini
- /etc/php/8.3/cli/conf.d/20-gettext.ini
- /etc/php/8.3/cli/conf.d/20-iconv.ini
- /etc/php/8.3/cli/conf.d/20-phar.ini
- /etc/php/8.3/cli/conf.d/20-posix.ini
- /etc/php/8.3/cli/conf.d/20-readline.ini
- /etc/php/8.3/cli/conf.d/20-shmop.ini
- /etc/php/8.3/cli/conf.d/20-sockets.ini
- /etc/php/8.3/cli/conf.d/20-sysvmsg.ini
- /etc/php/8.3/cli/conf.d/20-sysvsem.ini
- /etc/php/8.3/cli/conf.d/20-sysvshm.ini
- /etc/php/8.3/cli/conf.d/20-tokenizer.ini
You can also run `php --ini` in a terminal to see which files are used by PHP in CLI mode.
Alternatively, you can run Composer with `--ignore-platform-req=ext-dom` to temporarily ignore these required extensions.
