kenwheeler/slick ~1.8.1

Problem/Motivation

Your requirements could not be resolved to an installable set of packages.
Problem 1
- Root composer.json requires opigno/opigno_lms ^3.1.0 -> satisfiable by opigno/opigno_lms[3.1.0, 3.x-dev].
- opigno/opigno_lms[3.1.0, ..., 3.x-dev] require kenwheeler/slick ~1.8.1 -> found kenwheeler/slick[dev-master, 1.6.1] but it does not match the constraint.

Steps to reproduce

composer require opigno/opigno_lms:^3.1.0
