Error when running on Windows: sqlite3.OperationalError: no such module: fts4

[monocongo]

I am on a Windows 10 machine using Anaconda with fuzzymatcher installed from PyPI:

$ conda list | grep fuzzy
fuzzymatcher              0.0.5                    pypi_0    pypi
fuzzywuzzy                0.18.0                   pypi_0    pypi

When I run a Python script that uses fuzzymatcher I get the following error:

$ python match_addresses.py -c C:/home/data/good_addresses.csv -u C:/home/data/unmatched_addresses.csv
Traceback (most recent call last):

    con.execute(sql)
sqlite3.OperationalError: no such module: fts4

I have installed sqlite_fts4 but this hasn't helped.

$ conda list | grep fts4
sqlite-fts4               0.5.2                    pypi_0    pypi

I've even uninstalled fuzzymatcher and the reinstalled it fresh, thinking that maybe it finds the fts4 goodies it needs when installing but no luck, same error when I try again after doing that.

I do not have the same error when I run this code in the Windows Subsystem for Linux (Ubuntu 20.04) so I think this is a Windows-specific issue.

Thanks in advance for any suggestions on how to resolve this issue. In any event thanks to all the developers of this package, it's quite useful!

Hi!

I was using this package without any problems until I updated some packages in my environment and now I'm having this issue. I'm not sure which package blew this off. Have you figured out how to solve it?

Thanks!

Same issue on Win 10 Pro Version 10.0.19043 Build 19043 Python 3.8.8

Interesting. I also have Windows 10 Pro 19043.1052. I solved the issue by uninstalling Python 9.5.6 (which I installed by mistake) and keeping Python 3.8.8. Not sure why it's not working for you.
