Pip installing wrong version of a dependency - django - django

Question

I am running an old RHEL5 server and would like to install a beta version of the python module openrem from pip.
I create a virtual env in my folder and issue the command
pip install openrem==0.7.0b13
The setup.py for openrem 0.7.0b13 has the following requirements
requires = [
'django>=1.8,<1.9',
'django-filter >= 0.10',
'pytz >= 0a',
'humanize',
'pydicom >= 0.9.9',
'django-pagination',
'xlsxwriter',
'celery >= 3.1',
'argparse >= 1.2.1',
'django-qsstats-magic',
'python-dateutil',
'django-solo',
'django-crispy-forms'
]
However, I get the following message during the installation
Downloading/unpacking django>=1.8,<1.9 (from openrem==0.7.0b13)
Downloading Django-1.9rc1.tar.gz (7.3MB): 7.3MB downloaded
Running setup.py egg_info for package django
Low and behold django 1.9 is installed. The problem being openrem is incompatible with django 1.9. Why is pip ignoring the requirement to install django <1.9

Answer 1

All I've managed to dig up is this:
To mitigate this risk, do not use the foo >=0.3, <0.4 style
declaration, which has a purely numeric upper bound. <0.4 still admits
versions 0.4a0, 0.4a1, 0.4b0, 0.4c3, etc. Instead, use an upper bound
like <0.4a0, as in foo >=0.3, <0.4a0, when you write your
install_requires.

Perhaps you need to be more specific. You probably end up with django v 1.9.5 right? Seems a bit stupid, but there's probably some reason for it!
