Error while installing with Python "pip": Cannot fetch index base URL http://

Question

I am trying to install a local version of ScrumDo for testing. Only then I come to the point in my installation that I have to run:

source bin/activate
pip install -r requirements.txt

I get the error:

Downloading/unpacking django-storages

Cannot fetch index base URL http : //b.pypi.python.org/simple/
Could not find any downloads that satisfy the requirement django-storages

No distributions at all found for django-storages
Storing complete log in ./pip-log.txt

I googled a bit and search here and on Stack Overflow and found that I should add a --proxy= option and/or unset my http_proxy environment variable. Yet my install does not have a proxy and the environment var is not set. I tried running

pip install -r requirements.txt --proxy=

Yet the error remains the same. I also created a /root/.pip/pip.conf containing:

[global]
index-url = http : //b.pypi.python.org/simple

and checked it the server actually was online and if the package django-storages existed, this was both true.

a last thing I tried, since the install doc of ScrumDo says so:

pip install -U Django==1.1.4

yet again no succes... the error always remains the same, any one got any Ideas?

my pip-error.log shows the following (the URL works in firefox on a different machine in the same network that also uses no proxy):

Using following commands helped me. please try this

For upgrading pip python -m pip install --trusted-host pypi.python.org --trusted-host files.pythonhosted.org --trusted-host pypi.org --upgrade pip

For installing new packages, eg numpy, pandas etc. python -m pip install PACKAGE NAME --trusted-host pypi.python.org --trusted-host files.pythonhosted.org --trusted-host pypi.org

upgrade pip

I'm getting the exact same message, even from wget:

--2012-10-10 14:18:58--  http://pypi.python.org/simple/Django/
2012-10-10 14:18:58 ERROR 404: Not Found (Django does not have any releases).

That's very odd, the URL works fine on another computer, and wgetting the main page works fine.

EDIT: In my case, I had cached the IP in my /etc/hosts file for PyPI, and it was hitting that IP, which didn't work. After removing it and letting it use the normal DNS resolution procedure, it worked.
