I'm failing to install psycopg2 in a virtualenv and hoping someone can help. My efforts so far have blown it away across all virtualenvs. I have obviously installed an incompatible DLL file somewhere as follows ...File "C:\Users\mike\env\xxdx\lib\site-packages\django\db\backends\postgresql_psycopg2\base.py", line 25, in <module> raise ImproperlyConfigured("Error loading psycopg2 module: %s" % e) django.core.exceptions.ImproperlyConfigured: Error loading psycopg2 module: DLL load failed: %1 is not a valid Win32 application.
All my own fault. I had tried to install amd64 psycopg2 and didn't read the error message with an open mind. I only noticed this when I visited stickpeople (thanks Rasjid Wilcox and Xin Huang) and "Win32" jumped off the page. Both my Pythons are 32-bit.
All is now working as Guido intended but I obviously need to study wheels Thanks Mike
This is a Windows 8.1 laptop in an activated py2.7.9 env and Chris Gohlke's pre-compiled (where I think "pre-" means "presumably") psycopg2-2.5.5-cp27-none-win_amd64.whl from http://www.lfd.uci.edu/~gohlke/pythonlibs/ I realise Mr Gohlke offers no warranty/support etc. Pip 6.08 doesn't like me using such a downloaded wheel ... (xxdx) C:\Users\mike\env\xxdx\ssds>pip install C:\Users\mike\Downloads\python\postgresql\psycopg2-2.5.5-cp27-none-win_amd64.whl psycopg2-2.5.5-cp27-none-win_amd64.whl is not a supported wheel on this platform. ... and demands a compiler if I use the more common approach ...

Get it from http://aka.ms/vcpython27 Unfortunately, http://aka.ms/vcpython27 eventually leads to http://www.microsoft.com/en-us/download/confirmation.aspx?id=44266 and just does nothing. Having studied that page carefully and finding a "click here" if nothing happens after 30 seconds it seems there is no server to be found on the other side of that "click here". Does anyone have any suggestions?
