Hi, I started getting this error when trying to bootstrap Pants:

pants.base.exceptions.BackendConfigurationError: Failed to load the pants.core.register backend: ImportError("urllib3 v2.0 only supports OpenSSL 1.1.1+, currently the 'ssl' module is compiled with LibreSSL 2.8.3. See: <https://github.com/urllib3/urllib3/issues/2168>")

Seems to be related to breaking changes in

urllib3==2.x

, but downgrading it to

1.x

doesn't help. The error appears when I try to run any

pants

command using a binary created before this urrlib update. How do I fix it? Thanks!

Are you using the

./pants ...

script to run, or the new binary

pants

runner? If the first one, I think the new

pants

runner might resolve it. Alternatively, one can do it via a

PIP_CONSTRAINTS=...

/ constraints file, I think https://pantsbuild.slack.com/archives/C046T6T9U/p1683661374866099?thread_ts=1683574114.661669&cid=C046T6T9U walks through one way

I'm upgraded to pants

2.15.0

and switch to using the binary

pants

. This solved the problem, thank you!
