Hello. I've been suffering for 2 weeks now, I've broken my head. I can't get it started in any way. If anyone understands, I would like to ask for a detailed guide on installing on Windows. In Windows, I use Openserver 6. During the execution of the composer install command, it gives an error, requires the installation of gmp for php. I tried to uncomment in the php.ini settings, nothing works, when restarting php, comments are returned again and gmp does not work.
