 |
|
In emerging my packages, python3 seems to give issues. During an emerge -vuD world I get harfbuzz failing with:
| Code: |
File "/usr/lib64/python3.5/subprocess.py", line 127, in <module>
import _posixsubprocess
ImportError: dynamic module does not define module export function (PyInit__posixsubprocess)
|
eselect python list is
| Code: |
Available Python interpreters, in order of preference:
[1] python2.7
[2] python3.4
[3] python3.5
|
If I set 3.4 or 3.5 as the first to be selected, then emerge also fails to start with:
| Code: |
# emerge -vuD world
Traceback (most recent call last):
File "/usr/lib/python-exec/python3.5/emerge", line 7, in <module>
import platform
File "/usr/lib64/python3.5/platform.py", line 117, in <module>
import sys, os, re, subprocess
File "/usr/lib64/python3.5/subprocess.py", line 127, in <module>
import _posixsubprocess
ImportError: dynamic module does not define module export function (PyInit__posixsubprocess)
|
I'm now runnig a python-updater to see if it solves any problems. |

| It can be, that your environment contains PYTHONPATH that points to libraries for Python 2. Those are not compatible with Python 3, so they can not be properly used. At least here https://bbs.archlinux.org/viewtopic.php?id=226314 the person was getting the same error as you and had to clear the above variable. |

| If you have out-of-tree python stuff installed as a normal user, running portage under "su -" might help. |

| Found the problem. I am busy with a course in robotics and installed ROS on the system that set PYTHONPATH and nuked the rest. |
