py-pyside: cannot import PySide module

[tim@…]

sudo port install py-pyside succeeds but in Python import PySide gives "no module named PySide"

[larryv (Lawrence Velázquez)]

Thanks for the ticket. In the future, please Cc relevant port maintainers.

Are you sure you’re using the correct Python? If you installed py-pyside, then you got py27-pyside, and you need to be using /opt/local/bin/python2.7 (adjust appropriately for custom MacPorts prefix, of course).

[tim@…]

Hi. It is my intention and belief that I am using MacPorts python v2.7 Other modules I've added work fine as far as I can tell.

However, I am not using the the binary in /opt/local/bin/python2.7

I have relied on port --select

Am I doing something wrong? Apart from pyside, python works fine.

For example

import sip

gives no errors; the module loads. It seems to me there is something broken specifically for pyside.

here are some diagnostics

churchill:doc tim$ which python
/Library/Frameworks/Python.framework/Versions/2.7/bin/python
churchill:doc tim$ port select --list python
Available versions for python:
	none
	python25-apple

I have py27-pyside installed and cannot reproduce this. Does this directory exist?:

/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/PySide

[mamoll (Mark Moll)]

What is the output of this command?:

ls -l `which python`

See the FAQ about this. Please instead use:

port installed active

[tim@…]

Thanks for your support. I've answered your requests for more diagnostics below

(1) port installed active (see below)

(2) Does this directory exist?:

/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7 /site-packages/PySide

Answer: No. The directory PySide does not exist, although the parent directory does.

(3) what is

ls -l which python

churchill:python2.7 tim$  ls -l `which python`
lrwxr-xr-x  1 root  admin  7 23 Sep 22:08 /Library/Frameworks/Python.framework/Versions/2.7/bin/python -> python2

That's odd. First, /opt/local/bin is probably not at the beginning of your PATH environment variable if the system-installed version of python is found before the MacPorts version. However, if that directory doesn't exist, then "import PySide" wouldn't work either if you launched /opt/local/bin/python2.7. What is the output of this command?:

port contents py27-pyside

If it lists files that don't exist, try uninstalling and reinstalling py27-pyside.

[tim@…]

Right, my PATH was a real mess. All this time I thought macports installed python to /Library/Frameworks I'm going to fix this first, I think I will need to do quite a lot of reinstalling since many python modules are installed against a version I didn't want.

[mamoll (Mark Moll)]

So can this ticket be closed?

[tim@…]

well, if I still have problems, then it will be related to a different problem, so I think so. Thank again for your help.
