Al parecer genera conflicto de versiones pero no se como solucionarlo, les paso el error que me daponiendo:
composer require mercadopago/dx-php./composer.json has been updatedRunning composer update mercadopago/dx-phpLoading composer repositories with package informationUpdating dependenciesYour requirements could not be resolved to an installable set of packages. Problem 1 - mercadopago/dx-php[2.2.0, ..., 2.2.1] require doctrine/common ^2.6 -> found doctrine/common[v2.6.0, ..., 2.13.x-dev] but the package is fixed to 3.1.2 (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command. - Root composer.json requires mercadopago/dx-php ^2.2 -> satisfiable by mercadopago/dx-php[2.2.0, 2.2.1].Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.Tambien probé con composer require mercadopago/dx-php --with-all-dependencies pero me da error.Problem 1- Conclusion: don't install mercadopago/dx-php 2.2.1 (conflict analysis result)- Conclusion: don't install doctrine/common 2.13.3 (conflict analysis result)- sensio/framework-extra-bundle v5.6.1 conflicts with doctrine/persistence 1.2.0.etc.
