breaks virtualenv

[lukasz-virtualo]

Reproduction

1. Have a virtualenv with (some relevant) libs installed:

   Django==1.8.4
   django-cms==3.1.3
   

2. Install the slideshow:

   pip install django-slideshow==0.1.5

Symptoms

Does not occur prior to (2) above. Running any comand with manage.py:

Removing the lib from the virtualenv does not fix the problem, so damage is permanent.

Can't reproduce (you had a typo in your last step: the package is called djangocms-slideshow, not django-slideshow. Could that be your issue?

These are the steps I did:

mkvirtualenv test
pip install Django==1.8.4
pip install django-cms==3.1.3
pip install djangocms-slideshow==0.1.5

Output:
Successfully installed django-admin-sortable-1.6.7 django-sekizai-0.7 djangocms-slideshow-0.1.5 easy-thumbnails-2.0.1 pillow-3.0.0

There in fact is a typo in my previous post, as you pointed out:

pip install djangocms-slideshow==0.1.5

is the proper invocation.
Have you tried to execute:

python manage.py shell

after installing djangocms-slideshow?
Perhaps the problem affects other libraries than those listed. I include the complete contents of my venv:

Django==1.8.4
django-bower==5.0.4
django-classy-tags==0.6.2
django-cms==3.1.3
django-filebrowser-no-grappelli==3.6.1
django-reversion==1.9.3
django-sekizai==0.8.2
Django-Select2==4.3.1
django-treebeard==3.0
djangocms-admin-style==0.2.8
djangocms-column==1.5
djangocms-file==0.1
djangocms-flash==0.2.0
djangocms-googlemap==0.3
djangocms-inherit==0.1
djangocms-installer==0.8.0
djangocms-link==1.7.1
djangocms-picture==0.1
djangocms-style==1.5
djangocms-teaser==0.1
djangocms-text-ckeditor==2.8.0
djangocms-video==0.1
html5lib==0.9999999
Pillow==2.9.0
pytz==2015.4
six==1.9.0
tzlocal==1.2

I did try manage.py and didn't get an error. So you are right, it looks
like a dependancy problem. I know my plugin isn't thorougly tested,
especially the dependancies, and a lot has changed on django-cms. It was
developed against the 2.x series of django-cms. Sorry about that. You are
welcome to help improve it.
