Hello! I'm using Neovim and I got this message when I save the file at first, and then if I check with :PymodeLint
I've installed pylint with pip, pip install pylint

Same with #775, #774.
Sorry, a little confused here. Is it fixed or not yet?

[qwexvf]

Hello, i dont know why they still keep that fix in the master branch but you can switch to develop branch to get the fix.
if your using vim-plug for example

Plug 'python-mode/python-mode', {'branch': 'develop'}

Something like this.
Good luck sir.

[zeraus]

Hi @qwexvf, thanks for the answer. It's fixed somehow after last update.
I will try as you guided if I got it next time.
Again, thank you!

[eleijonmarck]

I still get same problem. It appears everytime. It is very annoying :(

[diraol]

@eleijonmarck you may need to clear the cache/compiled files:

[eleijonmarck]

Thanks that worked

I'm still having this issue. I'm using a brand new computer (formatted yesterday, reinstalled the OS), and even cleaning __pycache__ and *.pyc the error pops in.

Is changing options.linters_params['pylint'] by something options.linters_params.get('pylint') a valid solution? Why?

[diraol]

Hi @cuducos !

where exactly are you proposing to make this change?

Hum… ok, my bad. I should have better studied the way branches and releases work in this repo. Let me try to clarify. The error I'm getting is as follows:

However, now I see that this code is not present at the develop branch anymore. Thus I'm not sure if it still makes sense to do what I was planning to do, which was to use .get on the dictionary to avoid the KeyError…

[diraol]

No problem! You were probably using the master branch and, indeed, our current maintained working branch is the develop.

Take a look to see if it works if you change to the develop branch, please. ;)

[cuducos]

Take a look to see if it works if you change to the develop branch, please.

Indeed: worked like a charm. Many thanks : )
