9 years ago Hmmm. Using the absolute path, I get the same as above. That seems weird. Why would that be since it's in my PATH and which picks up both executables at that location.

9 years ago Can you cat the content of /usr/local/bin/pylint ?
I've also seen strange behaviours when there are multiple versions of pylint on a system.

sys.exit(run_pylint())So it is notably different..
I have not tested pylint 1.4 at the moment. All I can suggest is to force a reinstall of pylint ...

9 years ago Note too that pylint is using /usr/bin/python, whereas your default python is in /usr/local/bin.

9 years ago Grr. Used pip to uninstall and reinstall pylint, but it's still using /usr/bin/python (which is v2.7.6). The Homebrew installed Python is v2.7.9, for whatever that's worth. Am I doing something wrong in my setup? I don't do much Python dev, so there could be nuances of the configuration that I've missed or done incorrectly.

9 years ago Was your pip installed with /usr/bin/python or the Homebrew version ?
bgreenlee
commented
9 years ago I'm not sure how that's happening. You could try manually editing the pylint file and changing that to /usr/local/bin/python.
NotSqrt
commented
9 years ago I'm not sure if the shebang line is important, since sublimelinter forces the use of /usr/local/bin/python but it's worrth a try !

commented
9 years ago @NotSqrt To be honest, I'm not sure when/where/how pip was installed. At this point, I can only see that it's using the pip executable in /usr/local/bin/. A little reading seems to indicate that pip is installed automatically when installing Python via Homebrew. I'm going to try modifying the shebang now and see if that just gets things working.
robwilkerson
commented
9 years ago Well, guess not. I still get the same error(s) after modifying the shebang path. I'm not sure what's going on in my ecosystem that has things all bound up like this.

9 years ago And behind door #3 was the nuclear option. Uninstall pylint, uninstall all Python versions installed by Homebrew (apparently there were multiple--who knew?), reinstall pip. Apparently this is the price I pay for not having done enough Python development, but things do seem to be working okay using the native OSX Python executable.
Thanks for your help, everyone.

9 years ago That was definitely a strange problem, no matter what your python experience was ..

7 years ago Ran into same issue myself having installed python, pip and pylint via Homebrew. As such, the paths to the executables in my python environment were:
python: /usr/local/bin/python -> /usr/local/Cellar/python/2.7.12_1/bin/python (symlink)pylint: /usr/local/bin/pylintpip: /usr/local/bin/pip -> /usr/local/Cellar/python/2.7.12_1/bin/pip (symlink)Although my PATH and PYTHONPATH settings were correct to prefer the Homebrew python environment paths, there was one problem:
pylint executable shim had a shebang line at the top (#!/usr/local/opt/python/bin/python2.7 which pointed to OSX Python.framework path: /usr/local/opt/python/bin/python2.7 -> /usr/local/opt/python/Frameworks/Python.framework/Versions/2.7/bin/python2.7), it was somehow causing a conflict with the runtime environment of pylint and overriding the Homebrew python.In order to check how the Pylinter Sublime Text Package was starting pylint, I added a couple debug lines into the Pylinter code to check what it was using for python_bin, and pylint_path:

Because I preferred Homebrew for managing my python and pip versions, I edited the shim file and replaced the shebang line at the top with: #!/usr/local/bin/python to force the Homebrew python. Alternatively, it looks like I could have set pylint_path in my Sublime Text settings somewhere, but I could not get this to work (maybe I did not use the correct setting json variable name or type?).

I kind of hate creating an issue for this since I'm quite sure it's a me problem (I'm new to Python dev), but it seems like that's the preferred way of asking for help. Anyway, for the life of me, I cannot seem to get this to work. I've been working on this for hours now and reading everything I can find, but either nothing is working or I'm just not understanding it well enough to do it right. I'm hoping someone can point me in the right direction. Don't be afraid to get remedial.
I'm running Sublime Text (build 3065) on OS X. Python 2.7.9 is installed via Homebrew and pylint was installed via
pip install pylint. I'm working on a few scripts using Python 2.7 and they all begin with#!/usr/bin/env python.Relevant Console Output
