Trying to upgrade to 2.15 +

scie-pants

, two questions: 1. Is there extra steps to make scie-pants not try to download things each run? Previously

ENV PANTS_SETUP_CACHE="/root/.cache/pants/setup"

./pants version

in a docker image sufficed to then have it be able to run "offline". I tried with

RUN ./get-pants.sh

followed by the same thing (./ omitted), but no dice. Next invocation of pants still checks the fetch URL 2. Running the github action pants-init seemingly does not expose the scie-pants interpreter, as we get

$ pants list ::

2.)                                    /usr/bin/python3.8 CPython==3.8.10
3.)                                    /usr/bin/python2.7 CPython==2.7.18

for a plugin. The gha does blurt

Bootstrapping Pants 2.15.0 using cpython 3.9.15
Installing pantsbuild.pants==2.15.0 into a virtual environment at /home/runner/.cache/nce/d036c571b74670fb7cccdb2ee973b51625c6419b29dd5e2e5390d6267b873904/bindings/venvs/2.15.0

Do I need to configure

pants.toml

some way for it to discover the scie-pants interpreter for plugins?
