Description of the problem / feature request:

I have this in my WORKSPACE:

######################
# PYTHON SUPPORT

rules_python_version = "0.7.0"

http_archive(
    name = "rules_python",
    sha256 = "15f84594af9da06750ceb878abbf129241421e3abbd6e36893041188db67f2fb",
    strip_prefix = "rules_python-0.7.0",
    url = "https://github.com/bazelbuild/rules_python/archive/refs/tags/0.7.0.tar.gz",

load("@rules_python//python:repositories.bzl", "python_register_toolchains")

python_register_toolchains(
    name = "python39",
    # Available versions are listed in @rules_python//python:versions.bzl.
    python_version = "3.9",
)

load("@python39_resolved_interpreter//:defs.bzl", python_interpreter = "interpreter")
load("@rules_python//python:pip.bzl", "pip_install")

🐛 Bug Report: Actual Behavior

When I run a build (of any target) I get this error:
