Tell me more ×  I have a CentOS 5.5 box, which comes preloaded
with Python 2.4. I wanted 2.6, so used yumto get it from the
EPEL repository. I also used yum to install the psycopg2
package, but it installed it for Python 2.4.  I tried copying
/usr/lib/python2.4/site-packages/psycopg2/ to
/usr/lib/python2.6/site-packages/, and when I ran my script, it
worked... but it gave me a warning that said
/usr/lib/python2.6/site-packages/psycopg2/ RuntimeWarning:
Python C API version mismatch for module _psycopg: This Python
has API version 1013, module _psycopg has version 1012.  So it
looks like there's some kind of versioning issue going on here,
and I'm wondering what the best way to fix it is. Should I just
ignore the warning and carry on? Is there a way to use yum to
install psycopg2 for Python 2.6? Should I just install from
source using python26 install? I know installing from source is
generally a no-no in CentOS, so I want this to be a last resort,
unless it's the only option. I just don't want to mess up yum
