SOLVED:Modules not found on django migrations

I was making migrations on my django project when I encountered 2 modules not found; crispy_forms & storages.

My pip list is :

wheel               0.33.4
whitenoise          4.1.2

and the installed apps on my settings are

INSTALLED_APPS = [
     ....
    'crispy_forms',
    'storages',
]

When I try to migrate on heroku's bash I get:

psycopg2.errors.DuplicateTable: relation "blog_about" already exists

Anyone familiar with this?

Solution:

Re-installed crispy_forms at django storages
