SAGE hangs inside emacs

Question

I am running Ubuntu 12.04 and emacs 24.3. I have successfully downloaded sage, and sage_mode. My problem is that when I try to run SAGE in emacs it doesn't load.

When I try to run SAGE with M-x sage it will then say: Run sage (like this): /home/path/to/sage. I hit enter then everything freezes inside of emacs with a message in the mini-buffer: Sent python-eldoc-setup-code Emacs stays frozen until I quit with C-g After that SAGE appears normally. If I run sage in the terminal everything starts up quickly and normally as I would expect.

Here is the output from my messages buffer:

Sent python-shell-completion-setup-code
Sent python-ffap-setup-code
Sent python-eldoc-setup-code

Why is it freezing like this and not starting normally?

I have seen a few bug reports that look similar, which are specifically problems with the python shell (SAGE runs on top of python).

Here is one bug report.

EDIT: I am looking for specific instructions on how to fix the sage process that runs through emacs. Type M-x emacs-version I know that I have Emacs 24.3.1. Please let me know if you need any more information to help me fix my issue.

Thanks for all the help!

I'm sorry you're experiencing this.

This sounds like a bug (in sage-mode) that I fixed a while ago in which it would get stuck waiting for the prompt. What version of sage-mode are you using? C-h v sage-mode-version RET. The latest released version is 0.10 and doesn't have such a bug to the best of my knowledge. If you are using an older version please upgrade. Otherwise I would really appreciate a bug report at https://bitbucket.org/gvol/sage-mode/issues?status=new&status=open so that I don't forget it.

Also, what version of Sage are you using, and do you have anything in your ~/.sage/init.sage?
