My SDK taps started throwing an error over the weekend that looks like this:

meltano install extractor tap-gong

Failed to install plugin(s)

The taps are installed in a Docker container built from

meltano/meltano:v1.79.1-python3.8

. I am able to install them on my local machine's environment (i.e. only fails during the dockerized runs.) I am guessing I have done something wrong in the way I set up my tap requirements / pyproject file, but not sure what. Anyone seen this error before?

We are facing a similar issue, locally everything is working but only while building the docker container the installation process errors out:

Orchestrator 'airflow' could not be installed: failed to install plugin 'airflow'.

The pip_url which we are using is:

pip_url: psycopg2==2.9.1 apache-airflow==2.1.2 --constraint <https://raw.githubusercontent.com/apache/airflow/constraints-2.1.2/constraints-3.8.txt>

It suddenly started, also using meltano 1.79.1

@stephen_bailey thanks for reporting. I filed an issue for the SDK-based taps since I noticed the same thing: https://gitlab.com/meltano/sdk/-/issues/213. @martijn_wouters that MR above does seem to fix the issue for all pip plugins, so we'll get a patch out ASAP. I'm surprised no one has logged an issue in the Airflow repo, people will face this issue eventually when they upgrade

setuptools

I was wondering why my deploy failed ha, will be following this thread 👀

@edgar_ramirez_mondragon, <!subteam^S02BCD9FFEF> - I think a call 🤙 in 30 would be awesome. It seems like this is hitting the Python community pretty hard and fast. I'd like to better understand what actions (if anything) we can take in the next 24-48 hours. I'll drop a zoom link in #CKHP6G5V4

Amazing, thanks @maarten_van_gijssel !!
