[solved]A litttle problem with python pygtk and pyqt.

using_GNU · 2012-09-20 21:41:35

Greetings gentlemen.

when i try to launch screenlets, this happens:

[dragora@irya ~]$ screenlets
cat: /etc/screenlets/prefix: No existe el fichero o el directorio
Traceback (most recent call last):
  File "/usr/share/screenlets-manager/screenlets-manager.py", line 31, in <module>
    import pygtk
ImportError: No module named pygtk

when i try to launch wicd, this happens

dragora@irya ~]$ wicd-client 
Traceback (most recent call last):
  File "/usr/share/wicd/gtk/wicd-client.py", line 40, in <module>
    import gtk

and when i try to launch freecad, it works well, but a strange message prints in the terminal:

No module named PyQt4

I have pyqt and pygtk installed

[dragora@irya ~]$ pacman -Ss pyqt 
extra/eric 5.2.5-1

Which python version are you currently using? 2 or 3?

using_GNU · 2012-09-20 22:11:15

Both are installed on my system

Right. By default arch uses python3. A lot of applications are still using Python2. Try symlinking python to python2 instead of 3. That may be your issue.

using_GNU · 2012-09-21 07:43:19

Sorry, but how I do that?, What symbolic links i must create?, And where i place them?

Really, that should be a bug in the package then. Package managers need to make sure that all scripts in the package call the correct Python binary.

using_GNU: I wouldn't recommend symlinking python to python2 because that will break other Arch packages which all expect python to be a link to python3.

As a quick stopgap, if you set the environment variable PYTHON to /usr/bin/python2, assuming the screenlets script behaves, it should use python2 instead. Otherwise, find the screenlets script (presumably /usr/bin/screenlets; I don't have it installed) and change the first line from #!/usr/bin/python (or maybe #!env python) to #!/usr/bin/python2.

Edit: actually, the screenlets install script properly does the conversion: https://projects.archlinux.org/svntogit … k/PKGBUILD

using_GNU: can you post the output of

$ ls -l /usr/bin/python*

jakobcreutzfeldt · 2012-09-21 09:37:36

Ok...first of all, not related, but you only have Python 2 installed, not Python 3

Anyway, it's strange since pygtk is only available for Python 2 so it should work. I'm wondering if something got screwed up with your PYTHONPATH. Try running the Python 2 interpreter and importing pygtk:

$ python2
>>> import pygtk

Are any exceptions thrown?

using_GNU · 2012-09-21 09:47:26

ups...

this is the output

[dragora@irya ~]$ python2
Python 2.7.3 (default, Apr 24 2012, 00:00:54) 
[GCC 4.7.0 20120414 (prerelease)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import pygtk
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named pygtk

and

[dragora@irya ~]$ pacman -Ss pygtk
extra/pygtk 2.24.0-3 [instalado]
    Python bindings for the GTK widget set

This is strange...

what do you think?

jakobcreutzfeldt · 2012-09-21 09:52:02

What is the output of these commands in Python?

>>> import sys
>>> sys.path

jakobcreutzfeldt · 2012-09-21 09:54:39

Also:

$ ls -l /usr/lib/python2.7/site-packages/pygtk*
$ cat /usr/lib/python2.7/site-packages/pygtk.pth

using_GNU · 2012-09-21 09:55:46

>>> import sys
>>> sys.path
['', '/usr/lib/python27.zip', '/usr/lib/python2.7', '/usr/lib/python2.7/plat-linux2', '/usr/lib/python2.7/lib-tk', '/usr/lib/python2.7/lib-old', '/usr/lib/python2.7/lib-dynload', '/usr/lib/python2.7/site-packages']

using_GNU · 2012-09-21 09:59:41

[dragora@irya ~]$ ls -l /usr/lib/python2.7/site-packages/pygtk*
ls: no se puede acceder a /usr/lib/python2.7/site-packages/pygtk*: No existe el fichero o el directorio
/* it can't access because it doesn't exist???? */

:-(

[dragora@irya ~]$ cat /usr/lib/python2.7/site-packages/pygtk.pth
cat: /usr/lib/python2.7/site-packages/pygtk.pth: No existe el fichero o el directorio

:-( but i have pygtk installed

using_GNU · 2012-09-21 10:00:21

and i also have reinstalled all of these packages.

Strange, mine includes '/usr/lib/python2.7/site-packages/gtk-2.0'.

This isn't a permanent fix, but try this:

>>> import sys
>>> sys.path.append('/usr/lib/python2.7/site-packages/gtk-2.0')
>>> import gtk

WorMzy · 2012-09-21 10:06:15

Try re/installing python2-gobject2.

ok, but this is the result

using_GNU · 2012-09-21 10:17:04

Hey, the reinstalation of python2-gobject2 and python2-cairo, are making progress, now, the output is another:

jakobcreutzfeldt · 2012-09-21 10:31:55

Try installing python2-xdg

This is all weird. I'm tempted to tell you to just reinstall everything python-related.

jakobcreutzfeldt · 2012-09-21 10:36:32

Wait, screenlets depends on pyxdg. pyxdg doesn't exist, but instead it should be python2-xdg. So that required package wasn't installed when it should have been. This should be reported as a bug.

using_GNU · 2012-09-21 10:38:39

now it works, but i want to ask, if there is a comand in pacman that let me to reinstall every python2 related (packages that depends on python2).

once i've learned the comand, if exist, i will clasify this post as solved.

Thank you a lot for the unbeliavable help. You are awesome.

jakobcreutzfeldt · 2012-09-21 10:45:01

In principle, you can do this:

# pacman -S `pacman -Qqs python2`

However, if you have installed any Python2 packages from the AUR, it will fail. You can identify these packages in advance with

$ pacman -Qm

.

using_GNU · 2012-09-21 10:51:47

All in order now, let's see if this post help another people as well.

Thank you, until next time.

I hope I would help other people in the same way you helped me.
