Fixtures get loaded on composer install --env=prod --no-dev

[neumanniTech]

Hello,
we have the following problem with the DoctrineFixturesBundle when we want to install our project on our live server.
When we run for example composer install --env=prod --no-dev and after this the cache:clear script in composer.json gets executed we get the following error:

Executing script cache:clear [KO]
[KO]
Script cache:clear returned with error code 1
!!
!!   // Clearing the cache for the prod environment with debug false

!!  In AbstractRecursivePass.php line 179:

The problem exist also when we create a fresh new symfony project.
