Database possibly not being initialized on Windows

[goodmami]

It has been reported that Wn does not seem to initialize the database if the file is missing. See below:

>>> import wn
>>> for lexicon in wn.lexicons():
...     print (lexicon.id, lexicon.version, lexicon.label)

Running the above code without having a database led to the following error (username redacted):

  File "C:\Users\USERNAME\AppData\Local\Programs\Python\Python39\lib\site-packages\wn\_db.py", line 109, in _connect
    conn = sqlite3.connect(dbpath)
sqlite3.OperationalError: unable to open database file

I am unable to reproduce this on Linux, but there might be some kind of permissions issue that prevents the database from being created.

Turns out it's not a Windows thing. The problem is performing database operations (like wn.lexicons()) before the .wn_data directory is created. Executing a wn.download() creates the directory, then all is well.
