[Solved] ModuleNotFoundError: No module named 'xdg'

AxelG · December 20, 2020, 1:21pm

Dear all,

I’m running RPD on gentoo and thanks to @damonlynch we made it successfully install even on gentoo. So it worked well the recent month and today I get:

 $ rapid-photo-downloader
Traceback (most recent call last):
  File "/home/[xxx]/.local/bin/rapid-photo-downloader", line 5, in <module>
    from raphodo.rapid import main
  File "/home/[xxx]/.local/lib/python3.7/site-packages/raphodo/__init__.py", line 30, in <module>
    from xdg import BaseDirectory
ModuleNotFoundError: No module named 'xdg


 $ equery check pyxdg
* Checking dev-python/pyxdg-0.26-r2 ...
   66 out of 66 files passed

I donno the exact version… was it 2.9.23 or .24? Anyways I tried today to install the latest version and that also fails

  $ python3 ~/Downloads/install\(1\).py

Bitte installieren sie die folgenden Pakete über ihren Paket-Manager, und wiederholen sie danach die Installation:
wheel

Sorry, it is German. It says, pls go thru your system installer and installe “wheel”
but wheel-0.35.1-r1 is actually installed by the repo, so should be also found

$ equery files wheel

So now I am all lost…

damonlynch · December 20, 2020, 4:54pm

I am not familiar with gentoo. Is python mapped to Python 2 or 3?

What happens when you start python3 in the terminal and run this:

import xdg

AxelG · December 20, 2020, 10:22pm

no more python2 in gentoo

 $ python3
Python 3.7.9 (default, Oct 21 2020, 23:33:35) 
[GCC 9.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import xdg
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'xdg'
>>>

Seems my python is damaged somehow, not RPD just donno why and how to fix…
(on my lenovo T450s it still works, no comparison test though)

paperdigits · December 20, 2020, 10:31pm

If python modules are insalled with portage, then install the xdg python module, which is just called xdg. If you’re using pip, then pip install xdg.

AxelG · December 20, 2020, 10:39pm

O.k…
But what messed it? Up to now it did work
/shrug

paperdigits · December 20, 2020, 10:58pm

Looks like something uninstalled it

AxelG · December 21, 2020, 7:38am

Those are the xdg packages installed and they are the same than my laptop, where it still works (laptop even do not have pyxdg)

I freshly installed all xdg related packages to no avail…

Last thing to try is the MS-WIndows-Hack… reboot
…which also didn’t help :’-( but I have to admit, we are off topic here… SIGH

AxelG · December 21, 2020, 2:04pm

…and here comes the solution.

The problem for me was the multi-slot environment.

RPD looked to me like wanting python 3.7
on my system there is (inadvertently) 3.7, 3.8 and 3.9
3.7 was the active interpreter
still wheel got built with 3.8
I set 3.8 the active interpreter and now I could have freshly installed RPD and it works (on a first glance)
