pylint failing in conda environment

I'm unable to get basic usage of pylint in a conda virtual environment. If this just isn't yet supported, is there another linting tool I can use?

conda install pylint
pylint testfile.py

testfile.py:

#!/usr/bin/env python
print("hello, world")

pylint path:

$ which pylint
/home/me/anaconda3/envs/myenv/bin/pylint

$ conda list | grep pylint
pylint                    1.4.2                    py35_0    defaults

Traceback:

Solution

  • This problem has been fixed upstream at Bitbucket, and the code has percolated to pip, but not to Conda yet. Install it with pip for now.

    conda uninstall -y pylint
pip install --no-input pylint

    [edit] The pylint package has been updated in the Continuum repository, and you can now install pylint with Conda and Python 3.5 and it works without any trouble.
