Thanks for these links. I have bookmarked them. The problem is solved
now and therefore I don't have to compile for the moment. Fortunately :)
Cheers
Mike

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.
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/
<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 ...
(xxdx) C:\Users\mike\env\xxdx>pip install psycopg2
Collecting psycopg2

Unfortunately, http://aka.ms/vcpython27 eventually leads to
http://www.microsoft.com/en-__us/download/confirmation.aspx?__id=44266
<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?
Thanks
Mike
