pip install: How to force a specific package version

django, pip

Solution

This could/should/can be helped by clearing the build dir for Django in pip. There is a bug for this, since version 1.1 see here for details

You can start checking for these folders here if you're on OS X or unix like systems:

~/.pip 
/tmp/pip-build-root (or pip-build-$USER, if you aren't running pip as root).

This is if you haven't specified a new build folder when you installed the first version of Django.

Good luck!

Problem

I'm trying to install Django 1.4.3, but when I execute pip install, pip keeps installing Django 1.5 version instead 1.4.3 `sudo pip install -I Django==1.4.3` It returns: ``` Downloading/unpacking Django==1.4.3 Running setup.py egg_info for package Django warning: no previously-included files matching '__pycache__' found under directory '*' warning: no previously-included files matching '*.py[co]' found under directory '*' === >>>> Requested Django==1.4.3, but installing version 1.5 <<<< ==== Installing collected packages: Django Found existing installation: Django 1.5 Uninstalling Django: Successfully uninstalled Django Running setup.py install for Django warning: no previously-included files matching '__pycache__' found under directory '*' warning: no previously-included files matching '*.py[co]' found under directory '*' changing mode of /usr/local/bin/django-admin.py to 755 Successfully installed Django Cleaning up... ``` but if I execute pip freeze, it keeps showing Django==1.5 What am I doing wrong?
