Unable to have a working installation: libnacl issue − poetry install

I'm unable to get Silkaj working with Ubuntu 18.04 (with python 3.6.9 and pip 9.0.1)

I tried to install it with pip3 :

pip3 install silkaj --user

And run it with : ~/.local/bin/silkaj

But got an error with libnacl which is used by DuniterPy :

File "/home/dede/.local/lib/python3.6/site-packages/duniterpy/key/ascii_armor.py", line 17, in VERSION_FIELD_VALUE = "Python Libnacl " + libnacl.version AttributeError: module 'libnacl' has no attribute 'version'

Tried to install libnacl via apt but pip does not use it.

I don't understand why __version__ is not present in pip version of libnacl. Here is what print(libnacl.__file__) tells me :

/home/dede/.local/lib/python3.6/site-packages/libnacl/init.py

Which seems to be OK. I tried to uninstall and reinstall libnacl but got the same problem.

So, I tried to install it locally via poetry (don't know this tool) and seems that dependencies are not installed... When I tried : ~/.local/bin/poetry run silkaj I got this error : ModuleNotFoundError: No module named 'click'

Despite the fact that click is installed (at least via pip)...

I'm not a python expert, but I used pip for projects which uses click and didn't have any of those problems...

If someone can put me to the right direction it would be great.

Thanks, Andréas
