ipython-qtconsole not listed as optional dependency in Ubuntu

Checkout code
./bootstrap.py

from iPython.frontend.qt.kernelmanager import QtKernelManager
ImportError: No module named qt.kernelmanager

Ubuntu Linux 12.04

README should probably be updated to specify ipython-qtconsole as a dependency as this module is part of that package.

Cheers

Yes, you're right. But it's only an optional dependency. You should be able to run Spyder just fine without it.

I guess you have ipython but not ipython-qtconsole installed, right? In that case we have to look for its presence on Ubuntu, and not only for the ipython one.

Could you also please post the full traceback you're getting when running bootstrap.py?

Yes, that's right. I did think it was strange that iPython was only an optional dep but yet it failed.

This issue was updated by revision 675ed3b0779f .

In Ubuntu (and probably other Linux distros) qtconsole is installed in a
different package from regular ipython called ipython-qtconsole. So we not only
have to look for IPython when trying to initialize our IPython Console, but also
for the modules installed by this package, which fall under IPython.frontend.qt

Status: Fixed

Optional dependency the absence of which makes Spyder fail doesn't look like optional to me. =)

That's why I introduced the change, so that Spyder can start without IPython nor IPython.frontend.qt. Then our users could use the old external console as a Python interpreter.

But that makes the matter worse. The requirements list IPython, so People will install it, but not IPython.frontend.qt - and Spyder will still fail to work with IPython (yet it will not fail completely).

Well, you're right: we have to change the docs and list ipython-qtconsole (not ipython) as an optional dependency on Linux.

Besides, I'll remove my hack and search for IPython.frontend.qt explicitly now that I verified this works:

programs.is_module_installed('IPython.frontend.qt', '>0.12')

I thought is_module_installed didn't work like that but I was mistaken.

Is that ok with you?

This issue was updated by revision b6af71e36a57 .

-. IPython can be installed and work without its qt frontend, but we really need
the last one instead of the first.
-. Change suggested by Anatoly to remove the hack introduced in revision
675ed3b0779f on programs.is_module_installed
-. It clarifies the situation for the future when we decide to integrate the
IPython notebook.
