Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires phpunit/phpunit 9.6.3 -> satisfiable by phpunit/phpunit[9.6.3]. - phpunit/phpunit 9.6.3 requires ext-mbstring * -> it is missing from your system. Install or enable PHP's mbstring 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/10-pdo.ini - /etc/php/8.2/cli/conf.d/20-calendar.ini - /etc/php/8.2/cli/conf.d/20-ctype.ini - /etc/php/8.2/cli/conf.d/20-exif.ini - /etc/php/8.2/cli/conf.d/20-ffi.ini - /etc/php/8.2/cli/conf.d/20-fileinfo.ini - /etc/php/8.2/cli/conf.d/20-ftp.ini - /etc/php/8.2/cli/conf.d/20-gettext.ini - /etc/php/8.2/cli/conf.d/20-iconv.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-readline.ini - /etc/php/8.2/cli/conf.d/20-shmop.ini - /etc/php/8.2/cli/conf.d/20-sockets.ini - /etc/php/8.2/cli/conf.d/20-sysvmsg.ini - /etc/php/8.2/cli/conf.d/20-sysvsem.ini - /etc/php/8.2/cli/conf.d/20-sysvshm.ini - /etc/php/8.2/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-mbstring` to temporarily ignore these required extensions.
