Bug 510688 – net-misc/electrum-1.9.8 USE=-qt4 - electrum: ImportError: No module named qt

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description leonbaum2 2014-05-18 21:32:35 UTC]

If I emerge electrum with USE=-qt4, I get an error because it still depends on the python qt module:

$ electrum
Traceback (most recent call last):
  File "/usr/lib/python-exec/python2.7/electrum", line 190, in <module>
    gui = __import__('electrum_gui.' + gui_name, fromlist=['electrum_gui'])
ImportError: No module named qt

[Comment 1 mephinet 2014-08-14 11:15:54 UTC]

The issue is caused by this line in the electrum main script:

    if cmd == 'gui':
        gui_name = config.get('gui', 'classic')
        if gui_name in ['lite', 'classic']:
            gui_name = 'qt'

I guess, when using -qt, the default for the gui should be "gtk" instead of "classic". if gtk is deactivated as well, we should probably fall back to "text".

Work-around: specify --gui=gtk on the command line.

Doesn't work for me:

$ electrum --gui=gtk
Traceback (most recent call last):
  File "/usr/lib/python-exec/python2.7/electrum", line 190, in <module>
    gui = __import__('electrum_gui.' + gui_name, fromlist=['electrum_gui'])

    import gi
ImportError: No module named gi

It's because you do not have installed dev-python/pygobject:3. THe ebuild needs to be fixed since electrum switched to GTK3.

[Comment 4 ta2002 2014-10-28 19:04:40 UTC]

So you are saying that gtk+3 is required, even though it installs fine (but doesn't run) with gtk+2 (no gtk+3 on the machine at all)?

So do I need gkt+3 or pygobject:3 or both?

Actually you need both. There are wrong dependencies in the ebuild.

[Comment 6 Anthony Basile 2014-10-29 11:12:38 UTC]

I have not had time to give electrum any love.  Does someone have a patch for this?

This didn't help me.

My modified diff against electrum-1.9.8

I fixed the spaces and added a patch which helped me with my gtk+-3.12.2.

Gtk version requires clarification. With my 3.12.2 I had the error shown in Comment 9.

I've been waiting for upstream's next release but this isn't going to happen anytime soon.

@everyone, are Dmitri's patches working for you?  If so, I'll just apply.

@Dmitri. FYI, those patches won't apply cleanly anymore because of a fix to 1.9.8.  I can clean them up at my end, but you may want to know for yourself and others, eg, if you putting them in your /etc/portage/patches directory.

[Comment 13 Luke-Jr 2015-03-01 08:04:46 UTC]

Fixed this in the overlay.

[Comment 14 Anthony Basile 2015-03-05 21:58:19 UTC]

This should be fixed with 1.9.8-r1.  Please test and reopen if there's a problem.

I have the same problem with net-misc/electrum-2.1.1:

$ electrum -o -g qt

[Comment 16 Alexey Mishustin 2015-11-08 18:07:31 UTC]

And with gtk3 instead of qt4 it is launching OK.
