Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires cycle/database ^2.7.0 -> satisfiable by cycle/database[2.7.0, ..., 2.x-dev]. - cycle/database[2.7.0, ..., 2.x-dev] require ext-pdo * -> it is missing from your system. Install or enable PHP's pdo extension. To enable extensions, verify that they are enabled in your .ini files: - /etc/php/8.2/cli/php.ini - /etc/php/8.2/cli/conf.d/10-opcache.ini - /etc/php/8.2/cli/conf.d/15-xml.ini - /etc/php/8.2/cli/conf.d/20-ctype.ini - /etc/php/8.2/cli/conf.d/20-curl.ini - /etc/php/8.2/cli/conf.d/20-dom.ini - /etc/php/8.2/cli/conf.d/20-mbstring.ini - /etc/php/8.2/cli/conf.d/20-phar.ini - /etc/php/8.2/cli/conf.d/20-posix.ini - /etc/php/8.2/cli/conf.d/20-simplexml.ini - /etc/php/8.2/cli/conf.d/20-sockets.ini - /etc/php/8.2/cli/conf.d/20-tokenizer.ini - /etc/php/8.2/cli/conf.d/20-xmlwriter.ini - /etc/php/8.2/cli/conf.d/99-pecl.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-pdo` to temporarily ignore these required extensions.
