ImportError: No module named PySide

Orians · 2017-01-07 12:43:50

Hello everybody. Due to bussiness necessities I moved recently to Linux, and I'm having my firsts troubles dealing with it. Specifically, trying to run a program which needs PySide. I tried to intall it via pacman, yaourt, also I followed this guide (I know that the last one is for Ubuntu, but well, I need to try it, there's anything to lose), but afer all never works, showing the error mentioned in the subject. Somebody know what can I do to solve it?

I tried to install this packages through pacman/yaourt:

pyside-comon-tools
python-pyside
python-pyside-comon
python-pyside-tools
python2-pyside
python2-pyside-tools

The program works with python 2.7 (I already know how to switch between python3 and 2, so this isn't the problem), don't know if its relevant or not.

Thanks everybody in advance. By the way, as I said I'm a newbie in Linux, but also here. If you need further information, please tell me and I'll answer you as soon as possible.

Did you rebuild the python packages from the AUR after the update to python 3.6?

Also, welcome to Arch. Please make sure you read the code of conduct

Thats for the welcoming and the fast answer. My current python version is 3.5.2. So I think it wouldn't be the problem. Nevertheless I see this reddit post, and I followed the steps I see, with this result:

So, it seems they doesn't need a rebuild, right?

So you have not run a system upgrade since python in the official repositories was upgraded to version 3.6
What is the output of the following

$ pacman -Qi python-pyside python-pyside-common python-pyside-tools

grammar extraneous was

Thanks loqs for your answer. As you say, there are some things not updated. In my defense, I must say that the first program I tried (and suffered) to install was Spotify, and since I see how hard to deal with could be some packages (I said it, newbie coming from widnows...), I choose what seems to me the less foolhardy desition, don't change anything if it works until all the needed software is working.

Would prefer the system was up to date but I would not expect that to cause this issue.
What is the output of

$ pacman -Qkk python-pyside python-pyside-common python-pyside-tools

If

ls /usr/lib/python3.5/site-packages/PySide/

lists __init__.py in its output
then python / python3

import PySide

should find the module unless you have adjusted the standard search paths.
I am also out of ideas beyond suggesting you run a full system update.

(My output, don't know if relevant or not, sorry).
In case the issue is related with anaconda (and I know that the question is already moving out the scope of the initial question, and so of the post), there is an easy solution? Knowing that, I'll try to find an answer elsewhere, and if I find something usefull, I'll post it as soon as possible.

loqs · 2017-01-08 00:25:24

If the none anaconda python3 is still accessible on the system would run that and test if the import still fails.
As I am not familiar with anaconda can not answer the other question.

eschwartz · 2017-01-08 01:24:27

Testing what /usr/bin/python3 is, doesn't help unless you also confirm that that is the python3 you are using. I think anaconda prepends itself to your system $PATH.
Check the output of

type python3

If you didn't even know that you were running anaconda python, then you probably don't need it.... so uninstall anaconda and try again with plain old python.

Thaks Eschwartz.

$ type python3
python3 is /home/orians/anaconda3/bin/python3

Seems anaconda is making all go wrong, didn't it?? As far as I remember, I'll need it too, but well, knowing which package is causing the issue I can try to figure out how make them work properly

eschwartz · 2017-01-08 15:54:52

That doesn't look like a package, it is in your $HOME so it was probably build by hand. Regardless, letting anaconda be the default python is probably no safer than setting it to python2 -- plenty of system scripts follow the terrible upstream advice to use "#!/usr/bin/env python3" shebangs, and anaconda at a minimum won't have your pacman-installed python modules in /usr/lib/python3.6/site-packages/

So true. I followed quite literally some guidelines from a colleague, and well... now we have something to laugh about at the coffee break.

Good news, finally I mannaged to make all work. I reintalled anaconda (now as it should be done) and PySide packages, confirming they work ($python/2 / $import PySide). The rest of it in order to run the program was pretty straightforward (more or less, as I need to create a virtual environment for python2, migrate all the donwloaded python packages to it and deal with a minor bugfixing, but I survived to it)

That's all. Thank you all for helping and guiding me with this troublefixing.
