pylucene installation problem on Ubuntu 9.04

[KK]

hi all,
I've trying to install pylucene on my linux box from last 2 days but
not able to do so. first i tried to install it using apt-get like
this,
kk-laptop$ sudo apt-get install pylucene
and it did install python2.5, python2.5-minimal and pylucene. I must
mention one thing that I already had python2.6 on my box as the
default python i.e /usr/bin/python is linked to python2.6. Anyway s,
now i started the python interpreter using "python" command from cli
and then to make sure pylucene has been installed i tried to import
the module and to my surprise it said "module pylucene not found".
I thought I should enter the python2.6 env and do the same , so i
tried starting the python2.6 interpreter using "python2.6" as the
command and tried importing the same module and again it failed giving
the same irritating message.
As a final try i pulled the source code of pylucene and as per the
comments given there in the README file, copied the mentioned files to
site-packages directory of python2.6 and then tried importing the
module and then got the same error message saying no module name
pylucene is present. I'm sick of this error !
Can someone point me what is the issue? If it is due to multiple
version of python running on box, can someone tell me which one to
remove or someone tell me how to get the whole thing running? I'll
very much thankful to you guys.

Thanks,
KK.

If you installed using apt, have you a pylucene directory under /usr/
local/lib/python2.6/dist-packages/?

Also, if you run python, and import sys; print sys.path
whats it show?

Pylucene seems to have installed under Python 2.5. Python extensions
are only installed for one version of python and extensions that use C
may only work under one particular version. If you want to use that
package, run python2.5 from the command line and try importing it.

Yes I've a dirctory called dist-packages under python2.6 but that
doesn't contain anything on pylucene [it has lupyne, which i installed
day before yesterday and importing lupyne doesn't give any error msg,
but again it is dependent on pylucene]

From all of the above what I can see is we don't have any directory
named dist-packages under python2.5 but we've one under 2.6, then
where did all those pylucene files got installed to after i installed
it using apt-get? Any ideas?

Thanks

I tried doing something silly.
I went to the directory "/usr/local/lib/python2.6/site-packages" and
then tried to compile/run the file called PyLucene.py the way we
compile/run python scripts, then from there i started the python
interpreter by typing python ( which is actually python2.6), then i
tried to import that module, [un]fortunately it din't give that error
message but something else, you can see below:

kk-laptop:/usr/local/lib/python2.6/site-packages$ python
Python 2.6.2 (release26-maint, Apr 19 2009, 01:56:41)

file:///usr/local/gcc-3.4.6/lib/security/libgcj.security
file:///usr/local/gcc-3.4.6/lib/security/classpath.security
Falling back to standard GNU security provider
then tried to copy and paste my sample code for indexing data to
lucene, this way:


----------------------------
and surprisingly it din't give any other error. to crosscheck things i
went to the lucene index directory and fired LUKE and luckily found
that doc being indexed by lucene, even i tried searching for some
words and found they are working fine. So Pylucene seems to be working
partially, in my case. But I think python is not able to load the
PyLucene module (btw, i din't see any __init__ scripts which, i guess,
are used for bootstrapping external modules, right?). Then what is the
fix for this? do we have to add some __init__ scripts to make python
load PyLucene module when it starts? do i sound silly? What is the
best/easiest way to get this working? I've spend quite a lot of time
jsut to make PyLucene running but to no avail.
BTW, I tried to start the python interpreter from other locations and
tried imporitn this PyLucene module but got the same irritating error
message saying "module not found".
Also trying to run my sample indexer from cli using the normal way[kk-
laptop$ python indexer.py] gave the same error message.

Any help/advice is highly appreciated.
Thanks,
KK
