Bazel 7 ignores hermetic interpreter

[nikonikolov]

🐞 bug report

Affected Rule

The issue is caused by the rule: `py_binary`

Is this a regression?

Yes, the previous version in which this bug was not present was: bazel 6.4.0

Description

Bazel 7 falls back to system interpreter instead of hermetic interpreter

🔬 Minimal Reproduction

WORKSPACE:

load("@bazel_tools//tools/build_defs/repo:http.bzl", "http_archive")

http_archive(
    name = "rules_python",

    strip_prefix = "rules_python-0.32.1",
    url = "https://github.com/bazelbuild/rules_python/releases/download/0.32.1/rules_python-0.32.1.tar.gz",
)
load("@rules_python//python:repositories.bzl", "py_repositories", "python_register_toolchains")
py_repositories()

python_register_toolchains(
    name = "python_runtime",
    python_version = "3.10",
)

load("@python_runtime//:defs.bzl", python_interpreter = "interpreter")

load("@rules_python//python:pip.bzl", "pip_parse")

pip_parse(
    name = "pip-build",
    python_interpreter_target = python_interpreter,
    requirements_lock = "//:requirements.txt",
)

load("@pip-build//:requirements.bzl", pip_build_install_deps = "install_deps")

pip_build_install_deps()

BUILD:

load("@pip-build//:requirements.bzl", pip_build = "requirement")
load("@rules_python//python:defs.bzl", "py_binary")

py_binary(
    name = "ipython3",
    srcs = ["ipython3.py"],
    deps = [
        pip_build("ipython"),
    ],
)

    sys.exit(start_ipython())

🔥 Exception or Error

Running bazel run //:ipython3 drops to a python interpreter with version 3.11.9, which is not the 3.10 version specified in WORKSPACE, but the system version. Running import sys; print(sys.executable) from inside the interactive interpreter prints /usr/bin/python3

🌍 Your Environment

Operating System:

Slackware Linux (-current branch)

Output of bazel version:

  
Build label: 7.1.2

Rules_python version:

Anything else relevant? The above code works absolutely fine with bazel 6.4.0

I guess the reason is the same as https://github.com/bazelbuild/rules_python/issues/1675.

Closing as duplicate, if you have MODULE.bazel consider setting up rules_python with bzlmod. Most of the features (and sometimes more) exist on bzlmod.
