https://githubmemory.com/repo/camelot-dev/excalibur/issues/144 This fix worked for me after a whole lot of install commands failed.

The error message I was getting:

Traceback (most recent call last):
  File "/mnt/PERSONAL/TECH/python-scratch/python-virtual-environments/py3.8/bin/excalibur", line 5, in <module>
    from excalibur.cli import cli
  File "/mnt/PERSONAL/TECH/python-scratch/python-virtual-environments/py3.8/lib/python3.8/site-packages/excalibur/cli.py", line 10, in <module>
    from .tasks import split, extract
  File "/mnt/PERSONAL/TECH/python-scratch/python-virtual-environments/py3.8/lib/python3.8/site-packages/excalibur/tasks.py", line 13, in <module>
    from camelot.ext.ghostscript import Ghostscript
ModuleNotFoundError: No module named 'camelot.ext'

So I edited the mentioned tasks.py file,

Changed from camelot.ext.ghostscript import Ghostscript to from ghostscript import Ghostscript

And then it worked. Prior to this I had just installed Ghostscript, maybe there's a change in the recent packages.
