I installed psycopg2 in virtualenv using
easy_install psycopg2. I did not see any errors and looks like installation went fine.. there is an egg file created in the site-packages dir for psycopg2..
but when I run import psycopg2 in the interpreter, I am getting following error.. any clue? How can I fix it.. any other way to install psycopg2 in virtualenv..
Traceback (most recent call last): File "<stdin>", line 1, in <module> File "build\bdist.win32\egg\psycopg2\__init__.py", line 69, in <module> File "build\bdist.win32\egg\psycopg2\_psycopg.py", line 7, in <module> File "build\bdist.win32\egg\psycopg2\_psycopg.py", line 6, in __bootstrap__

I had the same problem. Following the suggestion on the download page of the Windows port for getting it working on Zope worked for me under virtualenv (also in the non-virtual install):
- Download the executable, rename the .exe extension to .zip
- Extract the file contents.
- Copy the psycopg2 folder to MyEnv/Lib
- Copy the egg to MyEnv/Lib/site-packages
Have you checked that PostgreSQL's 'bin' directory is on the system path? Check with a quick typing of 'set' and see what you get.
This is the most common cause of import failures of psycopg2 on Windows.
There is an alternative to install python packages in your computer i.e, pip . You can download python packages by just executing:-
pip install pyscopg2
The general format of the command is
pip install [package-name]
P.S:- To install python packages globally through pip
sudo pip install [package-name]
