Can't install Sage NB from Github

[Samuel]

I forked and cloned the sagenb repository on github. Following the instructions in the readme, I ran

../sage-5.0/./sage -python setup.py install

and then started up sage and ran:

import sagenb.notebook.notebook_object as nb
nb.notebook(directory="mynotebook")

I got this traceback

The notebook files are stored in: mynotebook.sagenb

Hi,

there are some dependencies that you've to install before installing the flask version of sagenb. Here are the instructions I've got from Basu(thanks!) to install sagenb.

How to get working with sagenb:

1. First download and install sage devel (or release version) from here for example: http://jambu.spms.ntu.edu.sg/sage/

2. Untar the file, and then cd sage-<release version> then type "make". This will take 3-4hours depending on the speed of your machine.

3. You have a working sage ready now. You may back up the directory sage-<release version> so that you can go back to it if anything goes wrong.

4. We will now upgrade the notebook to the flask notebook. Go to ticket 11080: http://trac.sagemath.org/sage_trac/ticket/11080 Install everything except openssl and the ticket from 12899. Just copy-paste the commands on to your terminal.

5. Now, go to SAGE_ROOT/devel and clone the github repository for sagenb. First fork sagemath/sagenb in github and then clone your own sagenb repository into a directory called sagenb-github (for example).

# fork sagemath/sagenb in github git clone git://github.com/<your username>/sagenb sagenb-github

6. You will now have a directory SAGE_ROOT/devel/sagenb-github. Symlink this directory to SAGE_ROOT/devel/sagenb:

cd SAGE_ROOT/devel rm -f sagenb ln -s ./sagenb-github ./sagenb

7. cd sagenb ../../sage -python setup.py develop

8. Start the sage notebook and check that you are actually running twistd-12.0.0. ../../sage -n

9. You can also add other sagenb repos like jasongrout/sagenb and sagemath/sagenb

Hello,

  Regarding 4., I gave this direction to jason because he already had openssl dev headers installed. If you don't have the openssl dev headers installed, then you need to install the openssl package too.

Thanks when I run notebook() it works great. When I run nb.notebook(directory="mynotebook") I get this though

The notebook files are stored in: mynotebook.sagenb

Please choose a new password for the Sage Notebook 'admin' user.

Do _not_ choose a stupid password, since anybody who could guess your password

and connect to your machine could access or delete your files.

NOTE: Only the hash of the password you type is stored by Sage.

You can change your password by typing notebook(reset=True).

Enter new password: 

Retype new password: 

Please login to the notebook with the username 'admin' and the above password.

Password changed for user 'admin'.

1. Do you get this same error if you run your notebook like this:

sage -n directory=mynotebook?

2. What if you append a sagenb at the end?

sage -n directory=mynotebook.sagenb

or, from inside sage prompt

notebook(directory="mynotebook.sagenb")

3. Is there any difference if you run it as notebook(directory="...") instead of nb.notebook(directory="...")?

[RickG]

I confirmed Samuel's report on OS X 10.6.  As for the last question, here's what I got:  

1. Do you get this same error if you run your notebook like this:

sage -n directory=mynotebook?

Yes.  

 

2. What if you append a sagenb at the end?

sage -n directory=mynotebook.sagenb

No.  Works fine.  

 

or, from inside sage prompt

notebook(directory="mynotebook.sagenb")

No, works fine.  But inside prompt using directory="mynotebook" gives the error.  

 

3. Is there any difference if you run it as notebook(directory="...") instead of nb.notebook(directory="...")?

 

No, "mynotebook" still fails, and "mynotebook.sagenb" still succeeds.

This confirms my suspicion that notebook directories must have .sagenb extension. :)
