Linter Not Starting in Jupyter Lab
I'm having a hard time getting started with Jupyterlab-flake8. I followed the installation instructions to the letter but the linter isn't starting up despite being toggled on. Flake8 linting works in Atom with linter-flake8, so I don't think it's a flake8-related issue.

After reading the following from the documentation, I confirmed that I can run the Terminal and Bash in Jupyter Labs.
Note: This extension will only work if you can load the terminal in jupyterlab.
In general I use zsh instead of bash though, not sure if that would affect anything.
I have the same problem using the most current Anaconda Platform which runs:
- jupyterlab 2.2.6
- flake8 3.8.4
Although I can see the configuration tab in the "advanced settings", it doesn't show in the "view" menu.
Is there any news on this? Thanks.
Try the new version (0.7.x) with JupyterLab 3, if you still have the same issue I will look into it more.
same issue with: jupyterlab 3.2.4 jupyterlab-flake8 0.7.1 flake8 4.0.1
any solution?
I have this same problem, the linter doesn't launch and the options in the view menu are greyed out:
jupyterlab 3.2.9 jupyterlab-flake8 0.7.1 flake8 4.0.1
On the offchance it makes a difference I'm accessing my jupyter lab in Chrome, over ssh using port forwarding.
The extension doesn't appear to be working in JupyterLab running on MyBinder.
MyBinder provides a useful ground truth for whether the extension works.
same here -- the extension is simply not activated
