Re: [sage-support] Re: Sage 8.8 Jupyter notebook 404: Page does not exist error

[slelievre]

Here is how I would recap Sage notebook modes and
ways to launch them (correct me if I got anything wrong).

- Jupyter Notebook

  sage -n jupyter

- JupyterLab

  sage -n jupyterlab

  note: this requires installing JuyterLab first,
  which one can do by running in the terminal

  sage --pip install jupyterlab

- SageNB legacy notebook

  sage -n sagenb

- Sage Exporter (to export legacy notebook worksheets
  to Jupyter Notebook documents):

  sage -n exporter

I think if you just run `sage -n` it will check whether
you have legacy sagenb worksheets, and if so give
you the option to run Sage Exporter or to launch a
Jupyter Notebook server.

If you know what you want, use one of the options above.

Note that instead of

sage -n jupyter

you can also do

sage --notebook=jupyter

and similarly for the other options.

Yeah, when it built i kept getting prompts about java and then at the end it 
said the documentation hadn’t been built successfully.

I only launch sage notebook from the terminal with the option -n so I guess 
I’ll just have to rebuild . Thanks anyway

Java development tools? 

But yes, something definitely didn't build, and I'm surprised it didn't 
give an error.  You may need to rebuild.

OR you could just try sage -n jupyter (I think this is the right syntax) 
and see where that gets you.

Actually I’ve just read more carefully what appeared in the terminal and it 
seems that it is missing an extension, I guess I’m going to have to rebuild? 
Could this be to do with the fact that I didn’t build the documentation 
(because I was missing the Java development tools ?)
