I was going to do that.... I was moving this discussion into it's own thread. But I did have a question about it before I installed it. It said that said 'After installation, where you would normally use sudo, non-root users will need to use sudopybrew:' is that in all instances or just when working with python?

This can probably be fixed via an installation of pythonbrew to create a new virtualvenv:
curl -kL http://xrl.us/pythonbrewinstall | bash
After that, pythonbrew installs itself to ~/.pythonbrew.

Please add the following line to the end of your ~/.bashrc:
[[ -s $HOME/.pythonbrew/etc/bashrc ]] && source $HOME/.pythonbrew/etc/bashrc


f the install script is run as root, pythonbrew will automatically install into /usr/local/pythonbrew.
The pythonbrew will be automatically configured for every user on the system if you install as root.

After installation, where you would normally use sudo, non-root users (which users get this error?) will need to use sudopybrew:
sudopybrew venv list
(and enter the other commands in the next section using "sudopybrew" instead of "pythonbrew")

OR if the error is incurred AS root, create isolated python environments (uses virtualenv):
pythonbrew venv init
pythonbrew venv create proj
pythonbrew venv list
pythonbrew venv use proj
pythonbrew venv delete proj
Show version:
pythonbrew version

If this does not fix your errors, it's going to be a complex packaging issue: read the links I sent and/or get someone to evaluate your packages.

If you don't fix it with a new venv init and create/use proj (as the user you are having issues with), remember to turn it off:




pythonbrew off

Why is it repeating the 'call'? Could you tell me how to fix it:

This "ImportError: No module named virtualenvwrapper.hook_loader" looks like a virtualenv python packaging problem: http://farmdev.com/thoughts/76/the-python-packaging-problem/

There is more available here, suggesting that you use pythonbrew and the newer command "venv" to manage your python modules: http://ubuntuforums.org/showthread.php?t=1571347

Here's a quick pythonbrew/venv module how to: http://pypi.python.org/pypi/pythonbrew/ It's a good possibility that it's not setup for system wide users (make sure you change to use the same version numbers for your install).

If you get the same errors, this is the packaging problem where virtualenv has broken dependencies.
