Python – Uninstall python modules

pythonvirtualenv

How to uninstall all python modules that where ocasionally installed. I need this cleanup (as if it is a fresh installation) to start working with virtualenv. Also I want to be sure that there's no intersection. Also I want to make sure that all preinstalled modules, i.e. needed by the OS, are left still.

The OS is Ubuntu 10.4 LTS.

If you installed the modules using apt-get, you can remove them using apt-get.

If you installed the modules using easy_install, they will be cataloged here: /usr/local/lib/python2.6/dist-packages/easy-install.pth

Here are good instructions for removing easy_install packages. stackoverflow - removing easy_install packages

When attempting to create pristine environments, it's always best to just start with an actual pristine environment. (fire up a fresh U10.04 VM and take stock of what libraries are installed and then do a diff)

Turns out this is extremely easy! I realise now that it builds against whatever version of python you launch setup.py with - in my case I had python symlinked to python2.5

So, instead of running python, run python2.6:

# python2.6 setup.py build
running build
running build_py
creating build/lib.linux-x86_64-2.6
copying _mysql_exceptions.py -> build/lib.linux-x86_64-2.6
creating build/lib.linux-x86_64-2.6/MySQLdb

Python/Django/WSGI/Apache – “ImportError: No module named site”

Your mod_wsgi was compiled for Python 2.7. You cannot then try and point it at a Python 2.5 virtual environment.

Also, the setting:

WSGIPythonHome /home/rory/tix/virtualenv2.5/lib/python2.5/

is pointing at the wrong thing even if it was a Python 2.7 virtual environment.

The settings:

UnSetEnv PYTHONSTARTUP
SetEnv PYTHONPATH /home/rory/tix/virtualenv2.5/lib/python2.5/

will not do anything either and don't know where you got the idea you could do that.

FWIW, the mod_wsgi documentation on virtual environments can be found at:

https://modwsgi.readthedocs.io/en/develop/user-guides/virtual-environments.html

This isn't going to help you though because you seem to have a more basic problem with your mod_wsgi and Python installations to begin with. The issue potentially being a variant of:

https://modwsgi.readthedocs.io/en/develop/user-guides/installation-issues.html#multiple-python-versions

Where did you get the mod_wsgi.so you are using?

Where is the Python 2.7 installed?

What other Python versions do you have installed and where?
