I'm trying to install psycopg2 so I can use postgresQL in python and Django. I have run into multiple errors in the last few hours trying to install it, and my latest one I can't seem to solve. When I run setup.py install on the psycopg2 in the command console it attempts to install it, but then gives me an error when trying to execute link.exein the Visual Studio 8 folder. This doesn't make sense to me, considering I got that executable to work when I launch it from Windows Explorer, and from the command console. I even made an environment variable for it. For some reason it keeps telling me "error: command C:\Program Files(x86)\Microsoft Visual Studio 9.0\VC\BIN\link.exe" failed with exit status 1120 I've looked extensively for a solution to this but everything I have tried didn't work. Anybody have suggestions or possible solutions?

Turns out this 3 and a half hour process I've been going through was unecessary. an exe installer of psycopg2 can be downloaded from here

In case anyone goes down this rabbit hole also, make sure your pip is up-to-date
pip install -U pip
pip install psycopg2-binary
See - http://initd.org/psycopg/docs/install.html
That's 3 hours of my life I won't get back.
