Hello Everyone ! I’m a devops engineer not familliar with Pants. I’m trying to allow Pants working with a SOCKS5 proxy to connect to a private python repository. • I followed the documentation here and pushed the environment variable required. Everything is working as expected, however I need to get

pysocks

library in the

venv used by Pants

(likely here

/home/circleci/.cache/pants/setup/bootstrap-Linux-x86_64/2.14.0_py38/lib/python3.8/site-packages

) Pip needs that library to retrieve packages, hence I have the error.

Looking in indexes: <https://pypi.org/simple/>, <https://admin>:****@python-index.xxxxx.fr/simple/
  ERROR: Could not install packages due to an EnvironmentError: Missing dependencies for SOCKS support.

I installed

pysocks

at system venv (with pip), this is working as expected, but not while running Pants. ➡️ Can you tell me how I can add a library to the venv used by pants ? Thank you very much for your help.

To get packages into the Pants env, you list them under

[GLOBAL].plugins

in your `pants.toml`: https://www.pantsbuild.org/docs/reference-global#plugins (doesn’t have to be just pants plugins..) However, if it is

PEX

that is installing, this may not be enough, and I’ll have to defer how to address that.. 🙂

I have some of them already. I thought it was not possible because

pysocks

is provided in no backend_packages in the documentation

backend_packages = [
  "pants.backend.python",
  "pants.backend.python.lint.black",
  "pants.backend.python.lint.flake8",
  "pants.backend.python.lint.pylint",
  "pants.backend.python.typecheck.mypy

So if I’d like to add

pysocks

I should just add

"pysocks"

to that array ?

Not the

backend_packages

but to

plugins

.

got it 😄 Thanks. I’m testing and will revert to you soon, thanks!

@bland-soccer-72046 including full command line output might be helpful. If you are correct about

~/.cache/pants/setup/...

, that Pants bootstrap is controlled by the

./pants

script and knows almost nothing of

pants.toml

save for the

pants_version

.
