Question

Answer 1

you can also do

heroku run pip freeze

that will give you a list of installed pip apps on heroku.. but ya also check your requirements.txt file

Answer 2

I had the same issue when running heroku run python manage.py migrate command. Here is what I did and solve the issue:

• Verify the crispy_forms in the INSTALLED_APPS under settings.py
• Run pip install --upgrade django-crispy-forms or pip3 install --upgrade django-crispy-forms depends on the Python version you are using (pip3 is for Python version 3 and above)

If the aboves didn't work, try Daniel Roseman's suggestion:

• Add this line django-crispy-forms==1.6.1 (version number will change so verify yourself here https://github.com/django-crispy-forms/django-crispy-forms/blob/dev/CHANGELOG.md) to requirements.txt file

This helped me and hope this will work for you as well. But don't forget to run (i) git add ., (ii) git commit -m "your comment", and (iii) git push heroku master before running heroku run python manage.py migrate command again.

Answer 3

if you haven't already, run this on your heroku platform:

pip install django-crispy-forms

remember that your local dependencies will not be installed automatically on your heroku dynos.
