has anyone else run into an issue with python3.9 + meltano 1.79.0 where

PIP_INDEX_URL

is suddenly being ignored?

I should note that it works as expected with python3.8 + meltano 1.79.0, so I imagine its either python3.9 related or an interaction between python3.9 and meltano 1.79.0

Hi @david_wallace! I'm not able to reproduce this bug

Copy code

$ meltano-personal git:(main) ✗ meltano --version
meltano, version 1.79.0

$ meltano-personal git:(main) ✗ python --version
Python 3.9.6

$ PIP_INDEX_URL=<https://pypi.python.org/simple> meltano --log-level info install extractor tap-github

The

PIP_INDEX_URL

environment variable does seem to be used. @florian.hines could this be related to https://gitlab.com/meltano/meltano/-/merge_requests/2256?

there is a chance it could be related to certain tap dependencies. Let me turn some knobs and circle back

@edgar_ramirez_mondragon if it was related to the

MELTANO__PYTHON_VERSION

change I think i’d expect it to impact other python versions too, but @david_wallace mentioned python3.8 + meltano 1.79.0 seemed ok.

@florian.hines thanks, makes sense 🙏

fwiw - poking around, I also can’t reproduce it.

my current hypothesis is that its due to the singer-sdk not being compatible with python 3.9

david_wallace

Im totally guessing but its the only thing I can come up with right now

edgar_ramirez_mondragon

@david_wallace ah that'd make sense. Any tap built with the SDK wouldn't be compatible with Python 3.9. @aaronsteers @taylor what do you about prioritizing https://gitlab.com/meltano/sdk/-/issues/66?

Yeah I think it makes sense! I added to the next milestone, but we can pull it up if it's quick.
