Error when calling sql.connect: ModuleNotFoundError: No module named 'packaging'

[edduardoo]

Code to reproduce

from databricks import sql
sql.connect('my_hostname', 'my_http_path')

Output

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<REDACTED>/.venv/lib/python3.11/site-packages/databricks/sql/__init__.py", line 88, in connect
    from .client import Connection

    from databricks.sql.thrift_backend import ThriftBackend

    import databricks.sql.auth.thrift_http_client

    from packaging import version
ModuleNotFoundError: No module named 'packaging'

Environment:

databricks-sql-connector Version: 4.0.2 (latest)
pip version: 25.0.1
Python version 3.11.9

Current workaround:

Downgraded to version 4.0.0, it works fine.

Hey @edduardoo
pip usually comes with packaging module installed. Perhaps there was an error in your installation. Could you try installing it manually via pip install packaging?

In my GitHub Actions environment, it's also missing. Adding packaging to my dependencies resolved the issue, but I think it should be included in this package if it's needed. For instance, wheel also relies on packaging (wheel pyproject)

Environement

pip version: 25.0.1
Python version 3.11.9

[build-system]
requires = ["setuptools==78.1.0", "wheel==0.46.0"]
build-backend = "setuptools.build_meta"

Got it, I'll look to add it to our python requirements setup!
