`sage -ipython` doesn't use the sage directory for ipython.

[itaibn]

The command sage -ipython uses ~/.ipython as it's configurations directory. This is probably not the intended behaviour, since programs installed through sage are not supposed to interfere with installed independently. In fact, if one installs the latest version of ipython and runs sage ipython it returns the following error message:

WARNING: Configuration file ipythonrc not found. Ignoring request.
------------------------------------------------------------
Traceback (most recent call last):
  File "/home/itaibn/sage-5.0.beta7/local/lib/python2.7/site-packages/IPython/ConfigLoader.py", line 66, in load

IOError: File'ipythonrc' not found in current or supplied directories:u'/home/itaibn/.ipython'

WARNING: Problems loading configuration file 'ipythonrc'
Starting with default -bare bones- configuration.

And then then continues with ipython in what is presumably the -bare bones- configuration.

This is probably a duplicate of #12911.

Replying to jhpalmieri:

This is probably a duplicate of #12911.

It seems similar, but I'm not sure. That ticket looks like it is about running something internal in sage rather the command-line interface, but it does seem similar.

Maybe it's not a duplicate. Unfortunately, the "obvious" patch

doesn't work: then sage --ipython has "sage: " as a prompt. I think that someone needs to improve how we deal with the IPython config files. See also #12167.

Fixed by #12719.
