Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires oxid-solution-catalysts/paypal-module dev-master -> satisfiable by oxid-solution-catalysts/paypal-module[dev-master]. - oxid-solution-catalysts/paypal-module dev-master requires oxid-solution-catalysts/paypal-client v1.0.10 -> satisfiable by oxid-solution-catalysts/paypal-client[v1.0.10] from composer repo (https://repo.packagist.org) but oxid-solution-catalysts/paypal-client[v1.0.3] from path repo (/build/oxid/project-modules/*) has higher repository priority. The packages with higher priority do not match your constraint and are therefore not installable. See https://getcomposer.org/repoprio for details and assistance.
