#   When ignore_base_python_conflict = true (the default), tox might ignore
#   any base_python settings for a particular testenv and instead just go
#   ahead and use whatever it can find that it thinks is the right version.
#   We instead want an error if the base_python is thought to be an
#   incorrect version for an environment with pyN.M in the name.

#   Specifying explicit paths to Pythons here doesn't seem to work; tox
#   complains about "env name py3.8-pytest5 conflicting with base python...",
#   regardless of the ignore_base_python_conflict setting. (More details at
#   <https://stackoverflow.com/q/77823499/107294>.) So for the moment, we
#   hack this by just having the Test script add all of the pythonz Pythons'
#   bin/ dirs to the path, and tox seems to find the right ones.
#   <https://stackoverflow.com/a/67308364/107294> might provide some
#   useful hints as to how to do this better.
