Getting a TypeError when running jupyter

I keep on getting a TypeError when running jupyter notebook Here is what is happening:

$ jupyter notebook

And, I am currently running version 4.4.0:

$ jupyter --version
4.4.0

I am also getting the same error message. I tried the proposed solution in this issue here, but it did not help

My conda environment in Ubuntu 16.06 with the following versions:

python 3.7.0
Jupyter 4.4.0

and the following conda info

$ conda info

             platform : linux-64
          conda version : 4.3.30
       conda is private : False

    conda-build version : not installed
         python version : 3.6.0.final.0

Do you have a BROWSER environment variable defined?

sdushantha commented 5 years ago

@minrk Yes I do. Am I not supposed to have it?

$ echo $BROWSER
firefox

It looks like this is a bug in the Python 3.7 webbrowser module.

Nicholas-Autio-Mitchell commented 5 years ago

There are other issues about this. Currently, I believe you have to stick to python 3.6.6 to be able to use the latest Jupyter.

I did hack the function producing the error to simply receive the correct number of arguments, and it all worked... Probably not recommended though, it just allowed me to continue without Internet for new installations etc.

Not sure what happened, but I updated my whole system (Manjaro Linux) and everything seems to work perfectly now.
