Galaxy LEfSe tool

I have been using LEfSe in the past and was successfully able to run the full pipeline with the Galaxy LEfSe tool. Now when I am trying to run the pipeline using new tabular files (I believe to be formatted correctly) and even old ones that successfully worked in the past I run into this error:
Traceback (most recent call last):
File “/usr/bin/”, line 10, in
from importlib.metadata import distribution
ModuleNotFoundError: No module named ‘importlib.metadata’
Can you please help me?

Hi @celia_silva
what Galaxy server do you use? Maybe add a server specific tag, so admins can check what is going on.
Kind regards,

Dear Igor,

Many thanks for your reply.

The site I used is


Kind regards,



Hi Celia,

I don’t know if admins from these sites check this forum. Maybe contact their support directly. The error message looks like an admin level issue.

Kind regards,
