Linter Not Starting in Jupyter Lab #41

Open CharlesARoy opened 3 years ago

CharlesARoy commented 3 years ago

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.

aflueckiger commented 3 years ago

I have the same problem using the most current Anaconda Platform which runs:

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.

filannim commented 3 years ago

Is there any news on this? Thanks.

mlshapiro commented 3 years ago

Try the new version (0.7.x) with JupyterLab 3, if you still have the same issue I will look into it more.

fedec15 commented 2 years ago

same issue with: jupyterlab 3.2.4 jupyterlab-flake8 0.7.1 flake8 4.0.1

any solution?

joshdorrington commented 2 years ago

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.

psychemedia commented 2 years ago

The extension doesn't appear to be working in JupyterLab running on MyBinder.

MyBinder provides a useful ground truth for whether the extension works.

ggrrll commented 11 months ago

same here -- the extension is simply not activated
