pywordnet install problems

hello pythoneers,

I recently tried to install wordnet 2.0 and pywordnet on both an ubuntu
linux running python 2.4 and a winXP running activePython 2.4.1, and I
get the exact same error on both when I try to "from wordnet import *"
:

running install
error: invalid Python installation: unable to open
/usr/lib/python2.4/config/Makefile (No such file or directory)

Adding the directories and files in question (touch Makefile) makes the
install go through but (obviously) breaks the import of wordnet.py:
import wordnet

Traceback (most recent call last):
File "<stdin>", line 1, in ?
File "wordnet.py", line 1348, in ?
N = Dictionary(NOUN, 'noun')
File "wordnet.py", line 799, in __init__
self.indexFile = _IndexFile(pos, filenameroot)
File "wordnet.py", line 945, in __init__
self.rewind()
File "wordnet.py", line 958, in rewind
if (line[0] != ' '):
IndexError: string index out of range

Is this pywordnet package abandoned, are there weird versioning issues,
or am I just extremely unlucky for the install to fail on two machines?

any help greatly appreciated,
vdrab.

Which version of WordNet do you have installed? I remember that when I
tried upgrading to the current version of WordNet, pywordnet broke. I
don't think the module is maintained very well; I've submitted a number
of bug reports and RFE patches and not had any of them responded to. If
I had the time, I'd pick up the project, but I don't at the moment...

hello Steve,

I had WordNet 2.0 installed but just now I tried it with 1.7.1 as well
and the result was the same. It's a shame, glossing over the pywordnet
page really made me want to give it a try.
Are there any workarounds you can recommend ?
I had a quick look at the wordnet.py file, and it looks readable enough
to try and fiddle around with it, but if possible I'd like to avoid
having to mess with the source file.
Is there any other person / list I can ask for help on this?

thanks a lot.
vdrab.

What's your wordnet setup like? I have mine installed in:
C:\Program Files\WordNet\2.0
and I have an environment variable WNHOME set:
WNHOME=C:\Program Files\WordNet\2.0
That seems to work for me.

Unfortunately, I wasn't able to find anyone else...

Thanks, I already figured it out a few days ago.

In the wordnet.py file, just override the path (WNHOME and/or WNSEARCH)
to the wordnet 2.0directory that has the lexnames files etc... (on my
ubuntu box: '/usr/share/wordnet')
That seems to fix it, although python gives a few warnings at startup.
checking the web it seems this is a known issue.
Thanks for the help though... I didn't bother posting the solution as I
thought noone was interested anymore.

cheers,
vdrab.
