Meltano

Is there some way I can configure `pip` through Meltano to resolve plugin dependencies from TestPyPI as a fallback if not found in PyPI?

I think you can set `PIP_EXTRA_INDEX_URL` to point to testpypi

<https://pip.pypa.io/en/stable/cli/pip_install/#cmdoption-extra-index-url|https://pip.pypa.io/en/stable/cli/pip_install/#cmdoption-extra-index-url> and <https://pip.pypa.io/en/stable/topics/configuration/#environment-variables|https://pip.pypa.io/en/stable/topics/configuration/#environment-variables>

Oh yeah, totally forgot you can configure pip like that! Thanks <@U06BX9QQ4A3>

(cc <@U06C8SN07SR> <@U06BXASUX6K> might be worth adding this to our run environment for future reference)
