Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires doctrine/common ^3.4.5 -> satisfiable by doctrine/common[3.4.5]. - doctrine/common 3.4.5 requires doctrine/persistence ^2.0 || ^3.0 -> found doctrine/persistence[2.0.0, ..., 2.5.7, 3.0.0, ..., 3.4.0] but it conflicts with your root composer.json require (^4.0.0). Problem 2 - Root composer.json requires doctrine/orm ^3.3.0 -> satisfiable by doctrine/orm[3.3.0]. - doctrine/orm 3.3.0 requires doctrine/persistence ^3.3.1 -> found doctrine/persistence[3.3.1, 3.3.2, 3.3.3, 3.4.0] but it conflicts with your root composer.json require (^4.0.0). Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.
