why i cant always

[shahab emami]

hello
i could never install an app from github
i get errors all the time

i do all of the installation process step by step but i cant at the end

can anybody help me in this?

for example i wanted to use this app in my project:
https://github.com/praekelt/django-likes
after 4 hours i got nothing except of this:

    "INSTALLED_APPS." % (module, name)
RuntimeError: Model class secretballot.models.Vote doesn't declare an explicit a
pp_label and isn't in an application in INSTALLED_APPS.
 
i know this is gonna sound really stupid but i feel that if I can do this there isn't anything i can't do in django

will you help me ? please?

python 3.6
django 1.10
thanks

The error message should be longer and contain useful information to
find what is wrong.

Without these information, I don't know where to look for the error.

have you installed django-secretballot ?

[shahab emami]

yes i installed it .
with this command:

python -m pip install django-secretballot

I have a question can you install this app on for yours?
because I believe if someone else can install this app for his project i can do it too.
thanks
