Jupyter nootbook not work

[Szabolcs Sződi]

Hi dear Somebody!

 I wrote "sage -n jupyter" comman on Jupyler nootbook interface, but not working. 

This is the answer:

 File "<ipython-input-1-2ee9f42db016>", line 1

    sage -n jupyter
                  ^
SyntaxError: invalid syntax

Please, help. Thank you. Kugli

You should not type that in a sage shell. In a terminal you could type that

user@host:~$ sage -n jupyter

but in a sage shell, you just want to type notebook() :

0 user@host:~$sage

Thank you Jan! 

Your answer is helpful, but not me. I'm not programmer only a user. I worked with maple, but SageManifold is seem better. I tried the next ones:

 1. open SageMath

2. open SageMath Shell

3. wrote Jupyter terminal: "user@host:~$ sage -n jupyter" (user? my name? need Jupyter log in? GitHub name?

4. wrote in Shell "0 user@host:~$sage"

I registered to GitHub, installed Anaconda...nothing.

There is something simply step by step instruction for simply, ordinary mortals? Couldn't find anything.

Thanks.

Aren't we supposed to tell it (how ?) to use Jupyter ?
