Spyder and PyQt

[se6git]

Got to the point of resignation on this one but I'll ask anyway.
Trying to get Spyder to work on Lion but keep getting:

Please check Spyder installation requirements:
PyQt4 4.4+ (or PySide 1.0+) is required.

Now, I have uninstalled and reinstalled both via the Riverbank installer and MacPorts versions. Ive also installed PySide. I've updated the Python path, prayed, burnt chicken feathers, sacrificed virgins etc. but nothing helps.
Does anybody have a clue what is going on here? I'm not a total novice but neither am I a geek so please, for the sake of my fragile sanity, keep the techno babble to the absolutely necessary.

Is the executable in your PATH? In your Terminal, enter the following command and show us the results:

echo $PATH

The message mentions specific versions of PyQt and PySide - do you have those versions installed?
Do you perhaps also have some other (older?) versions of these libraries installed? Maybe Spyder is finding the older version before the newer one.

Well, the version isn't the same, its 4.7 at least (have to check later). I did put the port install on the path but I suspect that there is an older version somewhere, or at least the memory of an older version somewhere causing issues. I read about this problem a few weeks ago on my last attempt to get Spyder working (I need a break after fighting with Qt4 issues - a not very long but very dull story). The advice was total uninstall and zap all memory of Qt4 and PyQt. Unfortunately the advice rapidly moved into a level of geekspeak beyond my comprehension and so I'm not sure if I got all possible traces of the older, developer version of PyQt out of my system.
Will try to reset and rewrite the Python path anew this evening (CET) and see if a clean flush helps.
Thanks for the help so far.

The which command can tell you what executable gets called.

For example, I've got two versions of sed installed on my computer:

% locate /bin/sed
/sw/bin/sed
/usr/bin/sed

If I issue the command which sed, I get

% which sed
/sw/bin/sed

It tells me the that the version installed by fink in /sw/bin gets called, in this case because it's first in my PATH.

Seems to be some permission error. I can launch a sort of functional Spyder if I use sudo but the console throws up:

Traceback (most recent call last):
File "spyder.py", line 1101, in plugin_focus_changed
self.variableexplorer.set_shellwidget(shell)
AttributeError: 'VariableExplorer' object has no attribute 'set_shellwidget'

whenever I try to do anything in Spyder.

I can check the PyQt4 instal if I launch Python with sudo:

Mon Nov 19 18:10:19 | $ sudo python

Type "help", "copyright", "credits" or "license" for more information.
>>> from PyQt4 import QtCore
>>> print QtCore.PYQT_VERSION_STR
4.9.4
>>>

but I can't see why the permissions shouldn't work:

Given up and am using TextWrangler and iPython. Both work and I can achieve almost all I wanted from Spyder. The only thing I really miss is the variable display, which, on my Ubuntu machine at least, is better than Matlab.
I'm sure I will survive this hardship.

Hmmm. Making another attempt, don't know why, maybe I've become addicted to the pain.
So trying to install again. Had to install sip again, even though I already had it, but the PyQt configure.py file insists it doesn't exist:

Wed Nov 28 14:17:04 | $ python configure.py
Error: This version of PyQt requires SIP v4.14.0 or later
Wed Nov 28 14:17:18 | $ sip -V
4.14.1
Wed Nov 28 14:17:23 | $

As you can see, sip exists and the version number is good. So, now that I have had my fix of pain for this round I can go back to ignoring Qt4, Nokia, Riverside and everything else.
