"No web browser found: could not locate runnable browser". Pages refuse to connect to launch Jupyter notebook.

tedmoorman commented 1 year ago

Description

Using the classical notebook, I receive the following message: "No web browser found: could not locate runnable browser". When clicking on browser extensions given in terminal, pages refuse to connect to launch Jupyter notebook.

Do I need to add some kind of firewall or port forwarding? I do this to create the initial Jupyter notebook that I'm launching from.

Reproduce

Install mamba_gator in conda environment.
Activate conda environment.
Run 'gator' command.
See message: "No web browser found: could not locate runnable browser".
Go to IP addresses in terminal, but they refuse to connect.

Expected behavior

I expected to be able to successfully launch a Jupyter notebook in the browser in which I could use mamba_gator.

Context

Python package version: mamba_gator 4.1.0

It was a port forwarding issue. gator --no-browser --port=xxxx --notebook-dir jupyter-folder did the trick.

Thanks for providing the fix @tedmoorman - closing this as answered.
