Problems running pylint 1.4.0
We have a rather peculiar software distribution system here at work. I downloaded, packaged, and installed astroid, logilab-common, and pylint. When I run pylint now (1.1.0 worked just fine), I get this error:
Traceback (most recent call last): File "/opt/local/bin/pylint", line 6, in <module> from pkg_resources import load_entry_point File "/home/skipm/.local/lib/python2.7/site-packages/pkg_resources.py", line 2805, in <module> working_set.require(__requires__) File "/home/skipm/.local/lib/python2.7/site-packages/pkg_resources.py", line 696, in require needed = self.resolve(parse_requirements(requirements)) File "/home/skipm/.local/lib/python2.7/site-packages/pkg_resources.py", line 594, in resolve raise DistributionNotFound(req) pkg_resources.DistributionNotFound: pylint==1.4.0
I see the (I think) necessary pylint bits in our site-packages directory:

I had a similar issue and the problem was that somehow I had two setuptools versions installed... and the older version was overwriting the new...
Hope that helps -- Joaquin Sargiotto El nov 25, 2014 5:54 p.m., "Skip Montanaro" skip.montanaro@gmail.com escribió:

But does your Python look in /opt/local/lib/python2.7/site-packages?
What does sys.path look like if you run the Python interpreter named in the #! line of the pylint script?

Ack! I'll bet that's the problem. Our production Python (/opt/local/bin/python) was compiled without debug symbols. Desperate at one point to step through the interpreter's C code, I built my own, and installed it in my directory space. I forgot about that when packaging pylint. It was found before /opt/local/bin/python.
Let me see if fixing that solves the problem. My guess is that it will.

That was it! Thanks for the excellent hint, Marius.
