我试图将我的Python软件包从setuptools切换到Poetry。由于我使用Tox来组织测试套件（带有短毛绒），因此我也必须调整tox.ini。重现该问题的Tox的最低配置如下所示：
[tox]
envlist = mypy,isort
isolated_build = true
skip_missing_interpreters = False
[testenv:mypy]
allowlist_externals = poetry
commands =
poetry install -v
[testenv:isort]
allowlist_externals = poetry
commands =
poetry install -v
如果我使用tox -e mypy,isort执行测试套件，则两个测试将成功执行。但是，如果我并行执行测试（以减少执行时间），则两个测试套件之一将失败，因为它找不到pyproject.toml：

如何实现在Tox中使用诗歌但可以并行运行测试环境？
