Pip Woes – The Maw

I was trying to hack some python together to read an Excel spreadsheet for work today and I just could not get openpyxl installed, pip kept throwing up errors:

% pip install openpyxl

ERROR: Could not find a version that satisfies the requirement openpyxl (from versions: none)

The way I managed to get around it was based on some information I found on Stack Exchange:

% pip install --trusted-host files.pythonhosted.org --trusted-host pypi.org --upgrade pip

Now pip works just fine and everything is hunky-dory.
