[SOLVED] Python3 - Import error subprocess after pacman -Syu

Hi there,

I am not sure it is related to archlinux, but since it happened after an update, I will still post here:

After a post-upgrade restart of my computer, Python3 cannot import the "subprocess" module.
I get the following error message:

    Traceback (most recent call last):
      File "/usr/bin/archey3", line 17, in <module>
        import subprocess, optparse, re, sys, configparser
      File "/usr/lib/python3.6/subprocess.py", line 136, in <module>
        import _posixsubprocess
    ImportError: dynamic module does not define module export function (PyInit__posixsubprocess)

Though, I don't know how to debug this issue, as none of the packages I upgraded were supposed, to my knowledge, to make any changes to my Python setup, as shows my pacman.log:

I don't know much about python, so I don't know how importing stuff works for it, but thats what happen when I search for _posixsubprocess on my system:

find / -name "_posixsubprocess.*" 2> /dev/null
/usr/lib/python3.6/lib-dynload/_posixsubprocess.cpython-36m-x86_64-linux-gnu.so
/usr/lib/python2.7/site-packages/_posixsubprocess.so

As you can see, there is a lib for python3, but it's not in site-packages, and it has a suffix with cpython... dunno what that is, nor how I can add it to python's default path..
Can anyone help me?

Thanks in advance

EDIT:
Issue solved by removing "/usr/lib/python2.7/site-packages:/usr/local/lib/python2.7/site-packages", that was appened to $PYTHONPATH in my zshrc. Probably somehow forcing python3 to search for subprocess at the wrong place.
Thanks everyone

Re: [SOLVED] Python3 - Import error subprocess after pacman -Syu

Never run pacman -Sy $package, it breaks things.

And it is your job to update AUR packages after libraries are bumped, not pacmans.

Re: [SOLVED] Python3 - Import error subprocess after pacman -Syu

Well damn! Thanks for the reply

So upgrading a single package was my mistake, because it also upgraded python in the background without consideration to other programs using the previous version of python...
But how can I fix my noob's mistake?
My AUR packages seem up to date, so I tried downgrading python from 3.6.1.1 -> 3.5.2-3, but once downgraded a python -V still shows "Python 3.6.1"

Re: [SOLVED] Python3 - Import error subprocess after pacman -Syu

Update your system.  pacman -Syu
Then, recheck your foreign packages (AUR stuff) and ensure they are still up to date.

Re: [SOLVED] Python3 - Import error subprocess after pacman -Syu

Thanks ewaller,

Thing is, I did so, and I still have the issue:

$ sudo pacman -Syu

 core is up to date
 extra is up to date
 community is up to date
 multilib is up to date
 archlinuxfr is up to date
:: Starting full system upgrade...
 there is nothing to do
$ yaourt -Syu
:: Synchronizing package databases...
 core is up to date
 extra is up to date
 community is up to date
 multilib is up to date
 archlinuxfr is up to date
$ archey3

  File "/usr/lib/python3.6/subprocess.py", line 136, in <module>
    import _posixsubprocess
ImportError: dynamic module does not define module export function (PyInit__posixsubprocess)

I know that yaourt is not the recommended way to maintain AUR packages...

Re: [SOLVED] Python3 - Import error subprocess after pacman -Syu

Running yaourt -Syu is exactly the same as running pacman -Syu - It doesn't check for updates to AUR packages.

Re: [SOLVED] Python3 - Import error subprocess after pacman -Syu

Try the following on your system and report back with the full output
What are the output of
pacman -Q python
pacman -Qo /usr/lib/python3.6/subprocess.py
ls -l /usr/lib/python3.6/subprocess.py
and
sha256sum /usr/lib/python3.6/subprocess.py

What happens if you enter the python shell from a console and try to import subprocess.py ?
When you get the error in post #1, how were you starting python?  With a python script (program)?  If so, please post the first few lines of that script.

Re: [SOLVED] Python3 - Import error subprocess after pacman -Syu

Okay, let's dig deeper.

What are the output of
pacman -Qo /usr/lib/python3.6/lib-dynload/_posixsubprocess.cpython-36m-x86_64-linux-gnu.so
and
ls -l /usr/lib/python3.6/lib-dynload/_posixsubprocess.cpython-36m-x86_64-linux-gnu.so

Edit:  Have you rebooted lately?

Also from python3.6.1-1:

Re: [SOLVED] Python3 - Import error subprocess after pacman -Syu

That hash matches mine as well.  BTW, I can import subprocess.py just fine
Can you import _posixsubprocess into the Python shell?  I'll bet you cannot.  I can.

Edit:  I assume this is x86_64.  As a sanity check, what is the output of uname -a

Re: [SOLVED] Python3 - Import error subprocess after pacman -Syu

Yeah, I get the same problem:

>>> import _posixsubprocess
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: dynamic module does not define module export function (PyInit__posixsubprocess)

Re: [SOLVED] Python3 - Import error subprocess after pacman -Syu

I am out of ideas.   Have you tried creating a new user with a clean profile and see if you can do the import?
Is PYTHONPATH set in your environmental variables?

Re: [SOLVED] Python3 - Import error subprocess after pacman -Syu

Hi, thanks ewaller!

I made a new user, logged in on a tty and imported subprocess successfully from command line.
So I checked the new user's $PYTHONPATH variable and noticed there wasn't anything in there.
On my account though, my .zshrc was overriding it with:

PYTHONPATH=${PYTHONPATH}:/usr/lib/python2.7/site-packages:/usr/local/lib/python2.7/site-packages

So I commented the line out to see what would happen, and now I don't have the problem anymore...
I don't really understand why adding these specific values to the empty $PYTHONPATH provoked the problem, but it's solved!
I tried adding an existing folder, and also non-existent path to PYTHONPATH just to see if it would reproduce the issue, but it didn't.

Thanks a lot for your help!

Re: [SOLVED] Python3 - Import error subprocess after pacman -Syu

I think you and ewaller found out the answer.
PYTHONPATH is look before that standard library directories, so when using Python3 you imported subprocess from Python2 because Python first before.
As test. Look what is the difference with the next Python commands too (using a Python 2 and 3 interpreters and with your PYTHONPATH and without it):

import sys
sys.path

Edit:
As always I must be wrong. Something you've fixed.
Because in your first post clearly it is importing from pyton 3.6

Traceback (most recent call last):
      File "/usr/bin/archey3", line 17, in <module>
        import subprocess, optparse, re, sys, configparser
      File "/usr/lib/python3.6/subprocess.py", line 136, in <module>
        import _posixsubprocess
    ImportError: dynamic module does not define module export function (PyInit__posixsubprocess)

Re: [SOLVED] Python3 - Import error subprocess after pacman -Syu

I think they may have been picking up _posixsubprocess from the wrong place, not subprocess itself. 
_posixsubprocess is imported by subprocess

Edit:. Also, be sure to edit your first post and change the title to prepend "[SOLVED]"
