Problem 1
- Installation request for mpociot/laravel-face-auth ^0.1.0 -> satisfiable by mpociot/laravel-face-auth[0.1.0].
- mpociot/laravel-face-auth 0.1.0 requires mockery/mockery ^0.9.9 -> satisfiable by mockery/mockery[0.9.9, 0.9.x-dev] but these conflict with your requirements or minimum-stability.

you need to run "composer require mockery/mockery:0.9.x-dev", not sure if the current version support latest mockery which is already 1.1.0
