Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires hprose/hprose-swoole ^2.0.12 -> satisfiable by hprose/hprose-swoole[v2.0.12]. - hprose/hprose-swoole v2.0.12 requires ext-hprose >=1.6.5 -> it is missing from your system. Install or enable PHP's hprose extension. To enable extensions, verify that they are enabled in your .ini files: - /usr/local/etc/php/7.4/php.ini - /usr/local/etc/php/7.4/conf.d/20-apcu.ini - /usr/local/etc/php/7.4/conf.d/20-igbinary.ini - /usr/local/etc/php/7.4/conf.d/20-msgpack.ini - /usr/local/etc/php/7.4/conf.d/20-redis.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-hprose` to temporarily ignore these required extensions.
