我在Windows 10上使用Python 3.6。我应该怎么做？有什么方法可以在不使用pip的情况下安装此软件包？我想用这个链接：https://pypi.python.org/pypi/pdfminer.six/20170720

我对编程很新，所以我不太了解。

这是一个代理问题，因为重试错误消息告诉你。您的点不通过代理连接到互联网。

尝试pip --proxy url:port pdfminer.six与url:port让您的代理服务器受阻proxy.example.com:8080。

如果这不起作用，请尝试使用另一个没有代理的互联网连接来通过pip安装软件包，或者看看这个thread，它有关于点和代理的更多答案。
