KeyError: 'collectstatic' When deploying the Django application to pythonanywhere

During the implementation of my Django application on pythonanywhere for the first time I encountered such an error. Previous applications with a very similar structure were able to be implemented without any problem

Traceback (most recent call last):
  File "/home/ebluedesign/.virtualenvs/ebluedesign.pythonanywhere.com/lib/python3.5/site-packages/django/core/management/__init__.py", line 204, in fetch_command

KeyError: 'collectstatic'
During handling of the above exception, another exception occurred:
