Troubleshooting Django Template Error: 'crispy-bootstrap4' Module Not Found did not work

Using Django Mystery Errors
1

This is my first time working with crispy_forms, and I encountered an issue with it:

TemplateDoesNotExist at /purchaseswe/categories/create/
bootstrap4/uni_form.html
Request Method: GET
Request URL: http://127.0.0.1:8000/purchaseswe/categories/create/
Django Version: 5.1.6
Exception Type: TemplateDoesNotExist
Exception Value: bootstrap4/uni_form.html
Exception Location: /home/Taha/.local/share/virtualenvs/store-6rOBssYB/lib/python3.13/site-packages/django/template/backends/django.py, line 130, in reraise
Raised during: purchases.views.CategoryCreateView
Python Executable: /home/Taha/.local/share/virtualenvs/store-6rOBssYB/bin/python
Python Version: 3.13.1
Python Path:

 '/home/Taha/.local/share/virtualenvs/store-6rOBssYB/lib/python3.13/site-packages']
Server time: Thu, 06 Feb 2025 01:24:01 +0000

I searched for a solution and found that the problem could be resolved by installing the crispy-bootstrap4 package. However, the bigger issue is that Python tells me the package is not found, even though I am using pipenv and am sure that it’s installed. I have tried the command multiple times and even tested it on another device with the same operating system, but the problem persists.

Here’s the error traceback that I received:

Please post the output of a pip list command, along with the contents of your INSTALLED_APPS and the CRISPY_TEMPLATE_PACK and CRISPY_ALLOWED_TEMPLATE_PACKS settings from your settings file.

Note, the most recent “released” version of crispy-bootstrap4 does not officially support Python 3.13. You may need to install the latest version from github for it to work.

The problem has become a bit more complicated. pyenv is not working on Fedora, even though the system is using Python 3.13. It feels like pyenv is not installed or not recognized, even with it being used.

That’s the wrong app name. Quoting from the docs at crispy-bootstrap4 · PyPI

    INSTALLED_APPS = (
        ...
        "crispy_forms",
        "crispy_bootstrap4",
        ...
    )

(Note: The hyphen, “-”, is not an allowable character in an app name. It’s always going to be an underscore, “_”.)
