navocab install instructions problem

[smrgeoinfo]

running windows, in conda, got poetry install using pipx.
following instructions in the tools/readme file. pip install requirements seems to work.
check out navocab repo, cd navocab, run
poetry install.
... stuff, then ends with
Installing the current project: navocab (0.1.0)
so looks like it worked...

but when try to run 'navocab --help', get...

(metadata_profile_earth_science) PS C:\Users\smrTu\OneDrive\Documents\GithubC\iSamples\navocab> navocab --help
navocab : The term 'navocab' is not recognized as the name of a cmdlet, function, script file, or operable program. 
Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

If I creat a pycharm project in the navocab repo and try to run the tests, they all fail.
TypeError: Vocabulary.__init__() got an unexpected keyword argument 'storage_uri'
