Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires coreshop/payment ^5.0 -> satisfiable by coreshop/payment[5.0.x-dev (alias of dev-master)]. - coreshop/payment dev-master requires coreshop/rule ^4.0 -> satisfiable by coreshop/rule[4.0.0-beta.1, ..., 4.1.x-dev] from composer repo (https://repo.packagist.org) but coreshop/rule[dev-master, 5.0.x-dev (alias of dev-master)] from path repo (../../*/*) has higher repository priority. The packages from the higher priority repository do not match your constraint and are therefore not installable. That repository is canonical so the lower priority repo's packages are not installable. See https://getcomposer.org/repoprio for details and assistance. - coreshop/payment 5.0.x-dev is an alias of coreshop/payment dev-master and thus requires it to be installed too.

Process completed with exit code 2.
