Python Autocomplete Error (Error: Command failed: bash -c #!/usr/bin/env bash)

[Marco Antonio Arruda]

Hello,

I've configured the python path and everything is working, but there's a console error message everytime I use the autocomplete (Ctrl+Space)

2931: 11960: Error: Command failed: bash -c #!/usr/bin/env bash
# Helper script to launch jedi/pylint in a python2/3 virtualenv
set -e

PYTHON=$1

 ENV=$FALLBACKENV
 if ! [[ -d $ENV ]]; then

Did I forget to install anything?

Up to now, I've installed virtualenv, so I suppose it install the rest of the dependencies inside the virtualenv used by C9, right?

Thanks!

I found this error in pylint-django repo issues: pylint-dev/pylint-django#108
After downgrading pylint to version 1.7.5, it was solved. Another error comes up though.

This message comes up in the console the first time I try to use the autocomplete: Error: Warning: python_linter not initialized yet

Is it normal? Because in the frontend nothing is shown. I was expecting a loading window or maybe a message that informs me to wait for python suggestion server. If not, I'd suggest this feature because as an user, no feedback after pressing Ctrl+Space is bad.

Thanks!
