Your requirements could not be resolved to an installable set of packages. Problem 1 - nikic/php-parser[v5.0.0alpha1, ..., 5.0.x-dev] require ext-ctype * -> it is missing from your system. Install or enable PHP's ctype extension. - Root composer.json requires nikic/php-parser ^5.0 -> satisfiable by nikic/php-parser[v5.0.0alpha1, ..., 5.0.x-dev]. 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-pdo.ini - /etc/php/8.3/cli/conf.d/15-xml.ini - /etc/php/8.3/cli/conf.d/20-dom.ini - /etc/php/8.3/cli/conf.d/20-mbstring.ini - /etc/php/8.3/cli/conf.d/20-pcov.ini - /etc/php/8.3/cli/conf.d/20-pdo_sqlite.ini - /etc/php/8.3/cli/conf.d/20-phar.ini - /etc/php/8.3/cli/conf.d/20-soap.ini - /etc/php/8.3/cli/conf.d/20-sqlite3.ini - /etc/php/8.3/cli/conf.d/20-tokenizer.ini - /etc/php/8.3/cli/conf.d/20-xmlwriter.ini - /etc/php/8.3/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-ctype` to temporarily ignore these required extensions.
