Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires amphp/quic dev-master -> satisfiable by amphp/quic[dev-master]. - amphp/quic dev-master requires ext-ffi * -> it is missing from your system. Install or enable PHP's ffi extension. To enable extensions, verify that they are enabled in your .ini files: - C:\tools\php\php.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-ffi` to temporarily ignore these required extensions.

Process completed with exit code 1.
