Question

我正在尝试设置环境以在新笔记本电脑上执行一些Python。我先做了brew install python3，然后去确保我用pip --version安装了pip。终端说我没有，所以我做了brew install pip。

然后我用pip install pipenv安装了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/.

搜索到这一点，我看到有人说pip的设置工具需要使用pip install --upgrade setuptools进行更新。当我尝试时，我得到了一个很长的错误，我将在下面发布。我已经超越了这个，并且不知道从哪里开始。任何和所有的帮助表示赞赏。

例外：

Answer 1

您已安装Python版本3但属于Python版本2的pip。首先，卸载已安装的pip。现在你应该安装pip3，例如使用brew install pip3。但是，pip3应该与Python 3一起安装，所以首先要确保pip3还没有安装。

无法安装pipenv，无法升级pip的设置工具
