When running the Magento 2 command bin/magento module:enable for a given module, the dependencies of that module (as declared in the sequence of its etc/module.xml file) is not enabled. This is a good thing, because not always does the sequence reflect all neccessary dependencies. But if so, this module gives you a command to enable all dependencies at once.

composer require yireo/magento2-enable-module-sequence
bin/magento module:enable Yireo_EnableModuleSequence
