I used the IUS Community and EPEL repositories to install python 2.6 on my RHEL 5.6 Tikanga box. However I faced some errors, which I didn’t see fully documented online so I figured they would come handy to myself and whoever else tries to do similar things.
Problem 1: Error on mkvirtualenv and other commands:
No module named virtualenvwrapper.hook_loader
Resolution: After looking at the source code, virtualenvwrapper can’t find our special python installation. Put the following line in your .bashrc:
along with the other two lines that everybody tells you to put in:
export WORKON_HOME=$HOME/.virtualenvs source /usr/bin/virtualenvwrapper.sh
(Note that virtualenvwrapper was installed to the above location, this is a different location than the one that everybody else (who is documenting the procedure) is installing at. I’m not sure if this is a new change in virtualenv or because of our special python26 installation. So use
locate to find your location properly.)
Problem 2: Virtualenvwrapper commands do not auto-complete or can’t be found also unless .bashrc is sourced manually.
Reason: .bashrc is not executed when logging in to the box (like it should be because it is listed inside .bash_profile, which should be executed also)
Solution: This happens because virtualmin setup’s default $SHELL for each non-root user is /bin/sh. To fix this for on user, open up
/etc/passwd, find the user that you are interested in, and change the
/bin/sh part to
/bin/bash. To fix the default for each virtualmin created user, go to virtualmin’s admin page, under System Customization > Custom Shells > Choose the /bin/bash custom shell.
