After i try to install with composer i get error this is full error from terminal.
Your requirements could not be resolved to an installable set of packages.

Problem 1
- Root composer.json requires designsecurity/progpilot ^0.8.0 -> satisfiable by designsecurity/progpilot[v0.8.0].
- designsecurity/progpilot v0.8.0 requires ircmaxell/php-cfg 1.0.x-dev -> found ircmaxell/php-cfg[v1.0.x-dev] but it does not match your minimum-stability.

Installation failed, deleting ./composer.json.
