Hey, I’m facing an issue and was hoping you could shade some light on it: Our internal PE team have decided to block access to public PyPi to prevent any potential vulnerability. Our Meltano project crashed because of this, with error

Extractor 'tap-zendesk' could not be installed: failed to upgrade pip to the latest version

. Am I correct to assume that this code runs when installing a tap/target, and that the default PyPi is the public one? Which would cause it to fail since fetching from public PyPi is not allowed. I tried to run with

plugins:
  extractors:
    - name: tap-zendesk
      variant: singer-io
      pip_url: -i <<https://interal_pypi_url.com>> tap-zendesk

but it does not work. In the case I’m correct, any chance we could update this line of code to be able to pass it a custom

--index_url -i

?

Correct

In the case I’m correct, any chance we could update this line of code to be able to pass it a custom 

--index_url -i

Yes, we could add a new

pip_index

setting! Can you please file an issue for that? We would want to use it both here: https://gitlab.com/meltano/meltano/-/blob/master/src/meltano/core/venv_service.py#L91 and here: https://gitlab.com/meltano/meltano/-/blob/master/src/meltano/core/venv_service.py#L126

yes will do!

That'd be even better! 😄

Thanks, responded!
