解决python - ImportError: No module named crispy-forms

桃扇骨 2022-05-21 08:57 303阅读 0赞

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 utility.execute() File "/usr/local/lib/python2.7/dist-packages/django/core/management/__init__.py", line 354, in execute django.setup() File "/usr/local/lib/python2.7/dist-packages/django/__init__.py", line 21, in setup apps.populate(settings.INSTALLED_APPS) File "/usr/local/lib/python2.7/dist-packages/django/apps/registry.py", line 85, in populate app_config = AppConfig.create(entry) File "/usr/local/lib/python2.7/dist-packages/django/apps/config.py", line 87, in create module = import_module(entry) File "/usr/lib/python2.7/importlib/__init__.py", line 37, in import_module __import__(name) 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:

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

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?

**Update 1** changes:

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...

As per the documentation : [http://django-crispy-forms.readthedocs.org/en/latest/install.html\#installing-django-crispy-forms][http_django-crispy-forms.readthedocs.org_en_latest_install.html_installing-django-crispy-forms], you have to add 'crispy\_forms' not 'crispy-forms' to your Installed Apps list.

It says: ImportError: No module named crispy\_forms instead :( –  beowwwulf Feb 17 '15 at 12:28      Hey, are you sure you installed crispy forms correctly, try running 'pip install django-crispy-forms'' in your virtaul environment. –  Abhishek Agarwala Feb 17 '15 at 12:38      Hey, I do think so... look at output pip freeze > requirements. Isnt it correct? –  beowwwulf Feb 17 '15 at 12:58      Yup, did you activate the virtual environment ? –  Abhishek Agarwala Feb 17 '15 at 13:54      yes, it was active.. I'm using eclipse in editing the files though. I would like to show the file structure, but I cant get tree to install. If I could I paste the whole dang thing here.. –  beowwwulf Feb 17 '15 at 14:43

I solve this problem right now, I realize 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`

Ok, so I found by chance(almost) another post, this one: [Getting stuck at Django error: No module named registration][Getting stuck at Django error_ No module named registration]

and thought it might have something to do with pythonpath.

so then I tried easy\_install, like suggested:

$ easy_install -Z django-crispy-forms Searching for django-crispy-forms Best match: django-crispy-forms 1.4.0 Adding django-crispy-forms 1.4.0 to easy-install.pth file Using /home/nr1/Envs/abc/lib/python2.7/site-packages Processing dependencies for django-crispy-forms Finished processing dependencies for django-crispy-forms

Now it works! I still think there might be something missing with the pythonpath, because I keep getting this in eclipse:

SignUpView Found at: __module_not_in_the_pythonpath__

, and I would like someone to clarify it, so feel free to contribute here...

but django and crispy\_forms now works together. YippikayeyMF!!

I use PyCharm for my Django projects. I get exactly the same error as you but in PyCharm until I change the Python interpreter used by PyCharm for the project. I have to, for each project, select the Python interpreter that resides in the relevant virtalenv folder to get the IDE (PyCharm) to recognize the installed modules. I suspect that the Pythonpath lurks somewhere in the background...

Doesn't Eclipse allow you to select the interpreter to use for a project? That's where I'd start looking.

Good luck!

answered Feb 21 '15 at 10:40 David Kaplan 1      Hey, thank you, but as I mentioned up there... it worked with: easy\_install -Z django-crispy-forms, for some reason... :) It didnt work with pip install django-crispy-forms. –  beowwwulf Feb 22 '15 at 23:34

I came across the same problem and figured out an alternate way around.

1.  Exit Virtualenv.
2.  Do a fresh pip install of crispy form at the root directory.
3.  Go back to Virtualenv and make migrations followed by migrate.

I think the django installation needs that all third party app be installed inside and as well outside the virtual env.  
I would really appreciate if someone could help me with inside details behind the reason.

All the above answers are missing one thing. Please cross check the location of your 'External Libraries' on the drive first before you do any of the above advises. Reason: - You be using an IDE that points to a different python directory, that is for guys who have install python more than once.

*  don't think your 'virtualenv' is pointing to the right directory were your 'External Libraries' are stored. So if you go ahead and install in a wrong directory then such error will ok

You have to make sure that you install crispy-forms into the virtualenv.

1.  Activate VirtualEnv (where env is the directory/name of your virtual environment):
    
    source env/bin/activate
2.  Install crispy-forms
    
    pip install django-crispy-forms
