Attempted to call an undefined method named "addClass" of class "Doctrine\O RM\Internal\CommitOrderCalculator

[simon-rad]

I have just installed a fresh instance of Symfony2.

composer require --dev doctrine/doctrine-fixtures-bundle

and when I run

php app/console doctrine:fixtures:load

I get this error

Attempted to call an undefined method named "addClass" of class "Doctrine\O RM\Internal\CommitOrderCalculator

I looked into the code and addClass is called on CommitOrderCalculator.
https://github.com/doctrine/data-fixtures/blob/master/lib/Doctrine/Common/DataFixtures/Purger/ORMPurger.php#L151

But I have checked Doctrine repository and they don't have such method.
