though, it's installed, python can't find pyqt4

[anatuss@…]

Hi, I'm using epd because of chaco (unfortunately it isn't available on macports). Recently I've started using QtDesigner with the intention to convert it into python language. But it isn't available on the epd. Hence I installed it with macports. Everything works fine until I tried to convert. I'm not good at making binaries work out. (I'd be glad if anyone could tell me what to do.)

What is the result of the following command?

port installed py26-pyqt4 python26 qt4-mac python_select

Also, what version of Mac OS X and Xcode are you running?

[anatuss@…]

Everything is up to date.... Mac OSX 10.6 and the Xcode version, which was necessary for installing 1.8.1 ... (Am I supposed to have a newer one ?)

The following ports are currently installed:
  py26-pyqt4 @4.6.1_0 (active)
  python26 @2.6.3_1+darwin (active)
  python_select @0.3_0+darwin_10 (active)
  qt4-mac @4.5.3_0+darwin_10 (active)

[mf2k (Frank Schima)]

That looks good. What is the output of the following command?

python_select -s

[anatuss@…]

python26 ... wie zu erwarten war

[anatuss@…]

sorry about that ...

To make PyQt work one needs to "configure" sip. This works for me. But ...

Traceback (most recent call last):

    import sipconfig
ImportError: No module named sipconfig

Though it's one directory up. I guess (but I don't know how to do this. I'd be glad to get a clue) the packages aren't "registered". Maybe one needs to use sys and change the path.

[anatuss@…]

well, I guess everyone knows how to deal with the last mentioned one. ... Of course, It works out. I've simple added

import sys sys.path.append('..')

After looking there's no PyQt4.py in there. So it cannot work ... Hence I've no idea to handle this ...

[Veence (Vincent)]

Can you check the .so files in your /o/l/L/F/P/V/2/l/p/s/PyQt4 are of the same arch as the python binary? Just type:

file Qt.so
file .../python2.6

and verify that they are suitable for the same arch.

[anatuss@…]

file Qt.so
Qt.so: Mach-O 64-bit bundle x86_64

file /System/Library/Frameworks/Python.framework/Versions/2.6/bin/python2.6
/System/Library/Frameworks/Python.framework/Versions/2.6/bin/python2.6: Mach-O universal binary with 3 architectures
/System/Library/Frameworks/Python.framework/Versions/2.6/bin/python2.6 (for architecture x86_64):	Mach-O 64-bit executable x86_64
/System/Library/Frameworks/Python.framework/Versions/2.6/bin/python2.6 (for architecture i386):	Mach-O executable i386
/System/Library/Frameworks/Python.framework/Versions/2.6/bin/python2.6 (for architecture ppc7400):	Mach-O executable ppc

So I guess, it suits

[Veence (Vincent)]

What about Qt itself? What is the result of:

file .../frameworks/QtCore.framework/Versions/4/QtCore
}}} ?

I have the same error, using py26-pyqt4, python2.6 from MacPorts. The problem is, that pyuic4-2.6 runs /usr/bin/pythonw, which starts the OS X native python interpreter, which does not know about the PyQt package from MacPorts. How can we change that? How does one select the python interpreter to use?

[mf2k (Frank Schima)]

I cannot reproduce this. Are you still seeing this problem with the latest version of py26-pyqt4?

[mf2k (Frank Schima)]

No response, closing.

[strassh@…]

I experience the same issue (all ouput commands describe in this post looks quite the same. I can't launch any pyQt programs (ImportError: No module named PyQt4) and python2.6 pyqtconfig.py can't be launched either.

$ port installed py26-pyqt4 python26 qt4-mac python_select
The following ports are currently installed:
  py26-pyqt4 @4.8.1_0 (active)
  python26 @2.6.6_0+no_tkinter (active)
  python_select @0.3_0 (active)
  qt4-mac @4.7.1_0+quartz (active)

$ python_select -s
python26

Thanks

Can someone give me a command-line to execute so that I can understand the issue? For me running python & then "import PyQt4" works just fine ... but maybe this is a "pyuic4" issue instead?

[mf2k (Frank Schima)]

Replying to strassh@…:

What is the output of the following?

which pyuic4-2.6

Also what is the output if you run "ls -l" on the result?

[michaelld (Michael Dickens)]

Here is what I get:

bash% which pyuic4-2.6 
/opt/local/bin/pyuic4-2.6

bash% ls -l `which pyuic4-2.6`
lrwxr-xr-x  1 root  wheel  70 Oct 17 20:18 /opt/local/bin/pyuic4-2.6@ -> /opt/local/Library/Frameworks/Python.framework/Versions/2.6/bin/pyuic4

[michaelld (Michael Dickens)]

@anatuss@…: Is this still an issue for you? If so, are your ports up to date? A lot has changed since this ticket was issued. "sudo port selfupdate" and then "sudo port upgrade outdated" often takes care of these older issues.

[ultramagneus@…]

I appear to be experiencing this issue, despite installing py27-pyqt4 via macports, I receive the error "ImportError: No module named PyQt4"

[ultramagneus@…]

Cc Me!

[michaelld (Michael Dickens)]

If this ticket is still valid, can you do the following:

sudo port clean py26-pyqt4
sudo port selfupdate

and then try to install or upgrade py26-pyqt4 again. There's a new qt4-mac and py26-pyqt4 that will hopefully fix this issue.

[michaelld (Michael Dickens)]

In the past few months, qt4-mac, phonon, and py27-pyqt4 have all been updated. Maybe these updates have fixed the issue of this ticket?

[michaelld (Michael Dickens)]

Closing due to lack of response, and that the issue should be fixed in the latest py-pyqt4 port.

I am definitely experiencing this. I did a 'sudo port install py27-pyqt4'. It compiled for awhile, no error message. Then:

[rif.a.saurous@…]

Whoops, wrong version of python. If I use /opt/local/bin/python2.7 it works.

[michaelld (Michael Dickens)]

I'm glad it's now verified working. Closing again.

[posines@…]

I have the same problem again.
