nox fails in CI even when nox.options.error_on_missing_interpreters = False #650
Description
Current Behavior
This PR makes CI fail if there are missing Python interpreters:
There was an exception for --no-error-on-missing-interpreters to override this behavior, but setting this in the noxfile.py itself does not work:
nox.options.error_on_missing_interpreters = FalseIn CI:
nox > Session test-3.9 was successful.
nox > Running session test-3.10
nox > Session test-3.10 failed: Python interpreter 3.10 not found.
nox > Ran multiple sessions:
nox > * test-3.9: success
nox > * test-3.10: failed
Expected Behavior
When nox.options.error_on_missing_interpreters = False is set, missing interpreters should not fail in CI.
Steps To Reproduce
Create a noxfile.py with
import nox
nox.options.error_on_missing_interpreters = False
@session(python=["3.9", "3.10"])
def test(s: Session) -> None:
...
Run this in a python:3.9 Docker image in GitLab CI.
nox > Session test-3.9 was successful.
nox > Running session test-3.10
nox > Session test-3.10 failed: Python interpreter 3.10 not found.
nox > Ran multiple sessions:
nox > * test-3.9: success
nox > * test-3.10: failed
