MacOS 上的 PIP 错误

我尝试在 Mac 上使用 PIP，但无法使用。缺少什么？如何修复？

pip --version

答案1

我建议你尝试pipenv，它是 pip 和 virtualenv 的薄包装器。它允许您创建独立的 pip 环境，这些环境不会相互干扰，也不会干扰全局 pip 配置。也许它可以帮助您绕过问题。

答案2

Python 的路径是否存在问题，是否有可能你已经删除了。

在这种情况下使用这些命令：

brew --prefix /lib/python2.7/site-packages

pip install -U pip 

pip3 install --upgrade pip

brew install pipenv
