A project that I am trying to use has a django import, so I am trying to install django.
In Windows.
I found directions on how to install it http://effbot.org/zone/django.htm#installing – and it requires a pull from an svn repository.
I have Mercurial hg installed – so I should not install svn – and https://www.mercurial-scm.org/wiki/WorkingWithSubversion says that I can just use a command like
svn co http://code.djangoproject.com/svn/django/trunk/django.
I am getting an error though, when I run it:
'svn' is not recognized as an internal or external command, operable program or batch file.
What can I do then, to install django, on Windows, when I have on my system already installed python27, sqlite, and postgres, and Mercurial ?
The documentation you pointed to is out of date. You do not need
svnorhgto install Django. I would recommend reading the official installation docs https://docs.djangoproject.com/en/1.4/intro/install/ and use a stable release rather than a checkout of the latest code.
