Installation not working on a Conda Python 3.7.7 environment

[tfabbri]

Please find below the error from the execution of the command motuclient - h from cli.

Traceback (most recent call last):
  File "/home/tommaso.fabbri/anaconda3/envs/casw/bin/motuclient", line 6, in <module>
    from motuclient import main
ImportError: cannot import name 'main' from 'motuclient' (/home/tommaso.fabbri/anaconda3/envs/casw/lib/python3.7/site-packages/motuclient/__init__.py)

I tried both the installation through pip and conda with the same outcome.
Something is missing in site-packages/motuclient directory (maybe the content of src/python directory).
Below you can find the installed content:
