problems with sagecell

asked 2019-03-04 13:19:11 +0200

Hi All,

I installed sagemath on Ubuntu 18.04 and am now trying to install and configure sagecell

pip install sagecell seem to work ok, but when I try to run sagecell it says:

root@shilo-ubu4:/var/tmp# sagecell
Error: No module named 'fabric'. You can install it by typing:
    sudo pip install fabric
or
    su -c "pip install fabric"

And yet fabric is installed:

root@shilo-ubu4:/var/tmp# pip install fabric
Requirement already satisfied: fabric in /usr/local/lib/python2.7/dist-packages
Requirement already satisfied: paramiko>=2.4 in /usr/local/lib/python2.7/dist-packages (from fabric)

Requirement already satisfied: pycparser in /usr/local/lib/python2.7/dist-packages (from cffi>=1.4.1->pynacl>=1.0.1->paramiko>=2.4->fabric)

So what am I missing here?

Thanks,

Oren

Maybe you can try

sage -pip install fabric

instead of pip install fabric

Eric,

I tried that but apparently, my sage installation does not support the -pip option. I don't see it in the docs either:

http://doc.sagemath.org/html/en/refer...

Do you have any idea why is this?

Thanks,

Oren

How did you install Sage?

The -pip option has been in Sage for a while (at least since Sage 6.5?). Are you using the Ubuntu package sagemath? If yes, it may be that -pipis not available through it. I would recommend then to uninstall this package and to install the binary for Ubuntu 18.04 available at http://www.sagemath.org/download-linu.... In addition, this will provide you with the latest stable release of Sage (version 8.6), while the Ubuntu package contains only Sage 8.1.

Please don't follow eric_g advice! Unless you need the very last features of SageMath, there is no reason to not use the Ubuntu package that is much better integrated into the distribution than the binary available on the sagemath website.
