Python ImportError in Django

Trying to run a Django project with this structure:

projectx

├──apps │ ├── app1 | | ├── __init__.py | | └── ... │ └── app2 | ├── __init__.py | └── ... ├──project │ ├── settings.py │ ├── urls.py │ ├── __init__.py | └── ... ├── manage.py └── ... 

During startup: python manage.py runserver I get ImportError: No module named apps

$ echo $PYTHONPATH gives
/ home / alexander / Work / projectx

Django version 1.9.8

 INSTALLED_APPS = [ ... 'apps.app1', 'apps.app2' ] 

My colleague launches this project without any changes, I think the point is in the PYTHONPATH variable.
