Python 由于需要，无法pip安装熊猫

我想用pip安装pandas

pip install pandas

但我有一个错误：

如何修复此问题？

您需要在同一环境中使用所有google cloud内容吗？不，我不需要。错误消息告诉您，您当前安装的软件包要求oauth2client低于4.0.0版。但是pandas需要oauth2client 4.0.0或更高版本。好了，没有干净的方法可以做到这一点。我想你可以通过

pkg\u资源

获得灵感。或者，如果您不需要同时使用proto google libs和pandas，您可以只安装两个不同的Python安装（需要更新PATH/PYTHONPATH以在它们之间切换）。或者只是卸载每个proto google库。然后我建议卸载google的东西，或者在干净的virtualenv中安装Pandas。哪一个？我卸载了oauth2client，但同样的消息不断出现
