I checked my usr/local/bin folder, and I have two versions of Python: v. 2.7.5 (used by Terminal) and Python 3.3 that I use with Eclipse.
The image of the bin folder is attached (I might be mistaken about what versions are installed, there might be more).
It doesn't seem to be the case that I have Python 2.x.y version collision (with another 2.x.z version).
When I try to install NLTK for v. 2.7 according to the instructions - using their installer/setup script, I get the message that there is no such module.
How can I fix this? I'd like to use NLTK (It used to work just fine in the past). Thanks in advance.
