Problem with `--extra-index-url`: My

requirements.txt

is like this

bagpy
roslz4 --extra-index-url <https://rospypi.github.io/simple/>

Using that in a venv with pip works fine for my app. But

pants

seems to not able to pick up the extra url:

stderr:
ERROR: Could not find a version that satisfies the requirement roslz4
ERROR: No matching distribution found for roslz4

None

How do I fix this problem? Look like

pex

has option to pick up

--extra-index-url

as well, but my guess is

pants

doesn't pass that to

pex

? More context: https://stackoverflow.com/questions/58754968/failed-to-load-python-extension-for-lz4-support-lz4-compression-will-not-be-ava

Hi there, you will want to set this in

pants.toml

[python-repos]
indexes.add = ["<https://rospypi.github.io/simple/>"]

Thanks! Will give it a try.
