Missing dependency 'pygtrie'

[joaomdsc]

I installed the betacode module with pip install betacode. Installation goes fine, but when I try to use it, it complains about a missing package 'pygtrie':

c:\a\src\py\tools\tei-xml>py tei.py Traceback (most recent call last): File "c:\a\src\py\tools\tei-xml\tei.py", line 3, in import betacode.conv File "C:\Program Files\Python39\lib\site-packages\betacode\conv.py", line 4, in import pygtrie ModuleNotFoundError: No module named 'pygtrie'

I was expecting pip to handle this sort of thing, installing dependencies as required.

I'm running python 3.9.1 on Windows 10.
