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/
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
Downloading psycopg2-2.6.tar.gz (367kB)
100% |################################| 368kB 650kB/s
Installing collected packages: psycopg2
Running setup.py install for psycopg2
building 'psycopg2._psycopg' extension
error: Microsoft Visual C++ 9.0 is required (Unable to find
vcvarsall.bat). 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?
Thanks
Mike
