[gentoo-science] [sage-on-gentoo] ImportError: No module named CrashHandler

[v_2e]

----------------------------------------------------------------------
  Hello!
  After upgrade to Sage 4.8 I cannot start it and get the following
error message:


| Sage Version 4.8, Release Date: 2012-01-20                         |
| Type notebook() for the GUI, and license() for information.        |
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/usr/bin/sage-ipython", line 19, in <module>
    from IPython.CrashHandler import CrashHandler
ImportError: No module named CrashHandler


  Is it a known issue? If it is, what is the solution?

  Thanks.
    Vladimir

Hi Vladimir,

You could try:

https://github.com/cschwan/sage-on-gentoo/issues/93

In the issue there was an IPython-0.10.1-py-2.7.egg-info file that was floating around. However, if this fixes things, it's odd that it's appearing again with 4.8, unless your ipython was recently upgraded?

  Yes, I saw that discussion and tried to apply the solution suggested
there before posting to this list. In my case I didn't find a file with
such name there.
  And by the way I upgraded the IPython to the version 0.12-r1 on
January 23. Could it be because of the recent upgrade?

  Thanks.
    Vladimir

Hi Vladimir,

ipython-0.12-r1 breaks things here with the same error you get.
There is no problem with ipython-0.10.2.

Hi,

I was warned on the sage-devel mailing list that ipython-0.11+ would break
things by one of the ipython lead developers. He wanted feedback on what would
happen with sage with newer ipython. I never got around to give him an answer
back because the ipython bump lagged in Gentoo. So I think we will 
restrict the
ipython version to 0.10.2 for the time being in sage.
