Python PIP 抛出错误 - ImportError : cannot import name main

Question

我对 python/pip 非常陌生，此时我只是摆弄一些事情，尝试安装我的环境，以便我可以开始测试该语言。

我已经正确安装了 PIP，但试图找到一些可以帮助我将解释器集成到 Jetbrains PyCharm 中的东西。我找到了一个名为 PIPEnv ( https://pypi.org/project/pipenv/ ) 的东西并安装了它，但现在它似乎破坏了 PIP

任何帮助都会很棒。

Answer 1

您可以尝试卸载pip和pip env。

Then reinstall pip and then try to again install pipenv. If this time it does not work then you need to use pip and virtualenv instead of pip env.

卸载它们，这次安装 pip 和 virtualenv
您可以配置 pycharm 以使用 virtualenv。
无论如何，这些命令对我有用
用于卸载

python3 -m pip3 uninstall pip3



sudo -H pip3 install --upgrade pip
sudo -H pip3 install pipenv

现在尝试执行“pipenv”
如果仍然不起作用，请尝试升级您的 python3。
如果您仍在使用python2.7，则将pip3替换为pip
