Install modules with no root privilegies
Alfons Nonell-Canals
Install python modules in a linux computer is really easy, it is because
the module is a package of the distribution or because the python
installation is really easy. But, in both situations, you need root
privilegies.
I would like to know how to install modules only for one user, with no
root privilegies. Do you know if it is possible and easy. I would like
to add that i need some modules only for my user and incly for one
progam.
Thanks in advance!
Alfons.

Yes, there is. You can choose among two strategies referred to as "home scheme"
and "prefix scheme" in the "Installing Python Modules" documentation:
http://docs.python.org/install/index.html
Have a look at Section 3 "Alternate installation".

As I just replied to another user (thinking I was responding to this
post), as of Python 2.6 / 3.0, if Python is not restricted to system
directories for security reasons (if sys.flags.no_user_site is non-0),
you may make a directory in your home directory to be searched. See
http://docs.python.org/library/site.html
for details on USER_SITE and USER_BASE.
That provides a searched location without having to cook up a custom
PYTHONPATH.

That's waaaaaaaaay much more than is actually needed, as thus each user
would end up with a different installation.
Setting the PYTHONPATH-env-variable to a user writable location allows e.g.
easy_install and friends to install into that location. And installing
virtualenv globally, everybody can create a "local"
site-packages-directory.

The "home scheme", you mean. It seems to me that this is exactly what
the poster wants -- mess with a bunch of modules without having to
consider anyone else's needs.

Yes, but the users have to trust everyone with write access to that
place. Someone could replace a module with a trojan horse, or simply
with a newer version which isn't compatible, and things would break.
Sometimes this is OK, but sometimes you only trust root and yourself.

Cannot comment -- I haven't used it.
