[Django]-Django returns 'TemplateDoesNotExist' when using Crispy Forms

if you need to use bootstrap4

1. pip install django-crispy-forms
2. pip install crispy-bootstrap4

inside settings.py in the main app add
INSTALLED_APPS = [ ... 'crispy_forms', 'crispy_bootstrap4', ... ]
and CRISPY_TEMPLATE_PACK = 'bootstrap4'

inside your_html.html file add
{% load crispy_forms_tags %} and you can use cripy_forms as you like

1. Run this command:

   pip install django-crispy-forms
   

2. Go to settings.py and add this in the installed apps (don’t forget the comma):

   "crispy_forms",
   "crispy_bootstrap4"
   

3. Add this after the installed apps (here there’s no need for a comma):

   CRISPY_ALLOWED_TEMPLATE_PACKS = "bootstrap4"
   CRISPY_TEMPLATE_PACK = 'bootstrap4'
   

4. Go to the html page where you want to add the crispy form and add this in the head section:

   {% load crispy_forms_tags %}
   

5. Finally add this to the body section:

   {{form|crispy_field}} 
   

I faced same issue and got solution. This is because you are using django-crispy-forms==2.0 and your project is not compatible with this version. also this django-crispy-forms==2.0 not support bootstrap4.

SOLUTION:
so install packages with below mention version:
(make sure python version > 3.7)

• pip3 install Django==4.1.6
• pip3 install django-allauth==0.52.0
• pip3 install django-crispy-forms==1.14.0 # version <=1.70
• pip3 install django-embed-video
