Composer conflicts when installingstof/doctrine-extensions-bundle on symfony 5 - composer-php

Question

when trying to install via composer require stof/doctrine-extensions-bundle I get a bunch of messages telling me that there is no way to install the package: Your requirements could not be resolved to an installable set of packages.
Part of the output is:

I have been installing, in this order:
composer require profiler --dev
composer require logger
composer require debug --dev
composer require annotations
composer require sec-checker --dev
composer require twig
composer require symfony/maker-bundle --dev
composer require doctrine
composer require form
composer require stof/doctrine-extensions-bundle
The latter is the first that threw an error

Answer 1

Through that list of requirements, you've installed doctrine/common in v3. The latest stable version of gedmo/doctrine-extensions is not yet compatible with that, which you can see in some issues.
You have two options: either wait for some more days or weeks until that package is made compatible, or downgrade doctrine/common before to v2. This is possible by using
composer require doctrine/common:"^2.11" doctrine/persistence:"^1.3"
