0.17.3 failing with Error in glob: empty segment not permitted

[phlax]

🐞 bug report

Affected Rule

Trying to use rules_python at all is causing this error - but the following targets the problematic rule:

$ bazel build @python3_10_x86_64-unknown-linux-gnu//:files

Is this a regression?

Current working version is 0.16.2

Description

Update rule_python add the python_repositories() load/deps

Any use of rules_python (or python toolchain specifically) throws an error

Do you have the disallow_empty_glob flag enabled?
bazelbuild/bazel#8195

[phlax]

afaict, not explicitly from

$ git grep allow_empty_glob
# nothing returned

but im wondering if our bazel version has flipped this - seems strange noone else seems to have hit it

not sure if this was something fishy with my local env - but either way on updating to 0.18.0 everything appears to work as expected
