Don't forget that you have to set not only your own path but also the
sudo path, to make sure that /usr/local/bin is in the same place
relative to /usr/bin in them both. If /usr/bin comes first then "python"
will mean python 2.5, otherwise 2.6.

You'll need to remove not only /usr/local/lib/python2.6, but also the
appropriate binary files in /usr/local/bin. I believe those are the only
two places affected by a local install.

Yes, I think this is happening - very frustrating!  I just wanted to
update python - Whenever I try install modules now though (e.g. sudo
aptitude install python-imaging), it doesn't install them in the new
folder  - why oh why

I just found this site http://jaredforsyth.com/content/install-python-26-ubuntu
that explains how to have an automatic install - which I did,  but now
my python path has got my other python 2.6 installation location. (I
now have one under /usr/lib/ and another under /usr/local/lib)

I've googled and googled and have not found out how you remove it
properly (If I were to remove it, I'd just delete the whole folder)

I don't know how to set my python path to point to the new python 2.6
folder either.


All in all, I'd rather just revert back to python 2.5 problem is
that I don't know how to do that either!!!

Sounds like Python 2.5 came with your Unix/Linux distro, and you have
added 2.6 by installing from source - by default it installs with
--prefix=/usr/local, I believe.

When you install something by running

  python setup.py install

it gets installed into the python that is used to run setup.py. It looks
like you had /usr/local/bin on your path when you installed django, but
not when you installed PIL and pysqlite2 (or maybe you just hadn't
installed Python 2.6 at that stage).

Either way, one version of Python won't see packages installed in another.

Re: sqlite3 problems setting up

[DragonSlayre]

Just doing some exploring - noticing that:

* /usr/lib/python2.5/site-packages has a pysqlite2 folder as well as a
PIL folder
* /usr/local/lib/python2.6/site-packages has just django in it

I'm not sure how the whole site-packages things work, or why python
2.5 is in /usr/lib/ and python 2.6 is in /usr/local/lib/ ?

Re: sqlite3 problems setting up

Importing sqlite3 fails as well (if I type this into a python
shell)

 import sqlite3
Traceback (most recent call last):
  File "", line 1, in 
  File "/usr/local/lib/python2.6/sqlite3/__init__.py", line 24, in

from dbapi2 import *
  File "/usr/local/lib/python2.6/sqlite3/dbapi2.py", line 27, in

from _sqlite3 import *
ImportError: No module named _sqlite3

sqlite3 is definitely installed, as I made a database and tested it
out
