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

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.

I am having the same problem as OP, except for `python-decouple`. I have tried steps 2 and 3 as suggested. However, I am wondering whether it is necessary to include `python-decouple` in the `INSTALLED_APPS` of `settings.py`? The README (https://github.com/henriquebastos/python-decouple) doesn't mention it, so how do we determine which modules must be included in `INSTALLED_APPS` and which don't? — Darcy, Oct 20 '18 at 02:59

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.

This won't work at all. `heroku run` starts up a new dyno; django-crispy-forms will be installed there, but not in the actual dyno running your app. – Daniel Roseman Oct 29 '15 at 18:25
We need to hear from the OP whether the app is included in requirements.txt. – Daniel Roseman Oct 29 '15 at 18:39
