*Thanks again for the suggestions. It doesn't look to me like it's installed in /usr/local/lib/python2.7/site-packages. There's an egg directory there, but otherwise, no psycopg2. The egg directory doesn't mean it's installed, does it?? Here's an ls of that site-packages dir:*
root@server [/usr/bin]# ls /usr/local/lib/python2.7/site-packages ./ setuptools-0.6c11-py2.7.egg-info ../ setuptools.pth distribute-0.6.35-py2.7.egg/ stevedore-0.12-py2.7.egg/ easy-install.pth virtualenv-1.9.1-py2.7.egg/ psycopg2-2.5.1-py2.7-linux-x86_64.egg/ virtualenv_clone-0.2.4-py2.7.egg/ README virtualenvwrapper-4.1.1-py2.7.egg/ setuptools-0.6c11-py2.7.egg *If I modify my sys.path, it still doesn't import psycopg2. The python command runs version 2.7.5 and you can see that in evidence in the sys path. It is looking at a different Python 2.7 that I installed under opt/bin and added to the PATH variable when I was trying to set up a virtualenvwrapper. * Here's a Python session: root@server [/usr/bin]# python Python 2.7.5 (default, Sep 25 2013, 10:45:19) [GCC 4.1.2 20080704 (Red Hat 4.1.2-54)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import sys >>> sys.path ['', '/opt/lib/python27.zip', '/opt/lib/python2.7', '/opt/lib/python2.7/plat- linux2', '/opt/lib/python2.7/lib-tk', '/opt/lib/python2.7/lib-old', '/opt/lib /python2.7/lib-dynload', '/opt/lib/python2.7/site-packages'] >>> sys.path.append('usr/local/lib/python2.7/site-packages') >>> import psycopg2 Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: No module named psycopg2 *But I can't get psycopg2 to install to the 2.7.5 directory. Its site-packages is completely empty:* root@server [/usr/bin]# ls /opt/lib/python2.7/site-packages ./ ../ README *whereas, /usr/lib64/python2.4/site-packages/ is full of stuff, including psycopg2. I've pasted just a small portion of the ls results below.* * * root@server [/usr/bin]# ls /usr/lib64/python2.4/site-packages/* * ortableServer.py* xf86config.py _gamin.a PortableServer.pyc* xf86config.pyc _gamin.la* PortableServer.pyo* xf86config.pyo gamin.py psycopg2/ *I also tried appending this path and importing. That gives a different error --tries to import it but fails, probably because it's inside a 2.4 install:* root@server [/usr/bin]# python Python 2.7.5 (default, Sep 25 2013, 10:45:19) [GCC 4.1.2 20080704 (Red Hat 4.1.2-54)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import sys >>> sys.path ['', '/opt/lib/python27.zip', '/opt/lib/python2.7', '/opt/lib/python2.7/plat- linux2', '/opt/lib/python2.7/lib-tk', '/opt/lib/python2.7/lib-old', '/opt/lib /python2.7/lib-dynload', '/opt/lib/python2.7/site-packages'] >>> sys.path.append('/usr/lib64/python2.4/site-packages/') >>> import psycopg2 Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/lib64/python2.4/site-packages/psycopg2/__init__.py", line 69, in <module> from _psycopg import BINARY, NUMBER, STRING, DATETIME, ROWID ImportError: /usr/lib64/python2.4/site-packages/psycopg2/_psycopg.so: undefin ed symbol: PyUnicodeUCS4_Decode Do you have other ideas?
