在虚拟环境/Pipfile中安装本地setup.py时出错

Question

我搞不清楚为什么我不能运行 pipenv install -e .。

我注意到一个可疑的地方，就是错误信息里提到的不是我虚拟环境里的 Python 版本（3.8），而是系统的版本（3.11）。

有没有人能看出我哪里做错了？

$ pipenv install -e .

  You can use $ pipenv run pip install <requirement_name> to bypass this mechanism, then run $ pipenv graph to inspect the versions actually installed in the virtualenv.
  Hint: try $ pipenv lock --pre if it is a pre-release dependency.
