I have no idea what's going on, but in any case you should make sure
your /usr/bin/python works and points to the system python2.6.  Maybe
"sudo yum reinstall python" is the way to go. Then perhaps you should
delete all Python2.7 files and try again (preferably, not in /usr -
that's for OS-installed files only. /usr/local is a nice place to put
things you installed from source)

The in some sense "official" way to get Python 2.7 on an EL6 system is
to install it through the software collections mechanism:
https://www.softwarecollections.org/en/scls/rhscl/python27/

Better yet, forget about Python 2.7 and use Python 3.7 (or 3.6, which is
available as an SCL)
