I'm working on some django apps, pretty noob still. Would like to use crispy-forms, but eclipse and django doesnt recognize it.

Trying to runserver or shell:

$ python manage.py runserver

this happens:

Traceback (most recent call last):
  File "manage.py", line 10, in <module>
    execute_from_command_line(sys.argv)
  File "/usr/local/lib/python2.7/dist-packages/django/core/management/__init__.py", line 385, in execute_from_command_line

ImportError: No module named crispy-forms

This is the forms.py I recently added to the site-folder alongside views.py, and it complains about unresolved import of crispy_forms...:

from django.contrib.auth.forms import UserCreationForm
from crispy_forms.helper import FormHelper
from crispy_forms.layout import Layout, ButtonHolder, Submit
from wx.lib.pubsub.core import kwargs

class RegistrationForm(UserCreationForm):
    def __init__(self, *args, **kwargs):
        super(RegistrationForm, self).__init__(*args, **kwargs)

        self.helper = FormHelper()
        self.helper.layout = Layout(
            'username',
            'password1',
            'password2',
            ButtonHolder(
                Submit('register', 
                       'Register', 
                       css_class='btn-prima'
                )
            )
        )

This is my part of my settings.py:

    INSTALLED_APPS = (
        'django.contrib.admin',
        'django.contrib.auth',
        'django.contrib.contenttypes',
        'django.contrib.sessions',
        'django.contrib.messages',
        'django.contrib.staticfiles',
        'polls',
        'crispy-forms',
    )

...
CRISPY_TEMPLATE_PACK = 'bootstrap'

I'm running virtualenv, my venv-dir looks like this:

venv/bin$ ls -la

I accidentally managed to type in: pip install python today, and it seems it did. Could that have any impact on it? I mean, isnt it virtualenv's task to make sure there is no software-conflicts?

Anyway, I cant get any Django-work going now until i figure this out, any help out there?

I now try to install crispy_forms to a completely project, looking in my virtualenv, I see its there:

So, its clear. Django doesn't even recognize that its installed it. How can that be?? virtualenv says its there, but django cant see it??? wtx...

I solved this problem right now, I realized that the crispy-form installed version was the python 2.7 version, but I'm using Django-1.10 with Python 3.5, and I think this is your problem too.

Try: pip3 install --user django-crispy-forms
