# if you use poetry with `virtualenvs.options.no-pip = true` you might end up with a
# virtualenv without pip, so the above trick doesn't actually work. See
# https://python-poetry.org/docs/configuration/#virtualenvsoptionsno-pip
#
# A possible option is to install `pip` into the virtualenv created by poetry
# (`poetry add pip`), but it turns out that doesn't always work :( for the test
# poetry/requests-3, I was not allowed to install pip! So I did not pursue this
# option further.
#
# Instead, local testing shows that first entry of `site.getsitepackages()` has the
# right path, whereas `site.getusersitepackages()` is about the system python (very
# confusing).
#
# We can't use the environment variable POETRY_VIRTUALENVS_OPTIONS_NO_PIP because it
# does not work, see https://github.com/python-poetry/poetry/issues/5906
