我正在尝试设置环境以在新笔记本电脑上执行一些 Python。我brew install python3先做了，然后去确保我安装了 pip pip --version。终端说我没有，所以我做了brew install pip。
然后我去安装 pipenv pip install pipenv。我收到此错误消息：
Command "python setup.py egg_info" failed with error code 1 in /private/var/folders/9t/pk6bmgc968d_fys24blkrgc40000gn/T/pip-build-o6M3Ve/pipenv/.
搜索时，我看到有人说 pip 的设置工具需要使用pip install --upgrade setuptools. 当我尝试这样做时，我得到了一个很长的错误，我将在下面发布。我对这个有点不知所措，不知道从哪里开始。任何和所有的帮助表示赞赏。
例外：
