Your requirements could not be resolved to an installable set of packages.
Problem 1
- Root composer.json requires simplesamlphp/simplesamlphp ^2.1 -> satisfiable by simplesamlphp/simplesamlphp[2.1.0, ..., v2.4.2].
- simplesamlphp/simplesamlphp[2.1.0, ..., v2.4.2] require ext-session * -> it is missing from your system. Install or enable PHP's session extension.
To enable extensions, verify that they are enabled in your .ini files:
- /etc/php84/php.ini
- /etc/php84/conf.d/00_ctype.ini
- /etc/php84/conf.d/00_curl.ini
- /etc/php84/conf.d/00_dom.ini
- /etc/php84/conf.d/00_iconv.ini
- /etc/php84/conf.d/00_intl.ini
- /etc/php84/conf.d/00_mbstring.ini
- /etc/php84/conf.d/00_openssl.ini
- /etc/php84/conf.d/00_simplexml.ini
- /etc/php84/conf.d/00_tokenizer.ini
- /etc/php84/conf.d/00_xmlwriter.ini
- /etc/php84/conf.d/01_phar.ini
- /etc/php84/conf.d/10_igbinary.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-session` to temporarily ignore these required extensions.
