无法在Windows 10上安装pdfminer.six

Question

在我的cmd窗口中，键入

pip install pdfminer.six

这给了我这些错误。

我在Windows 10上使用Python 3.6。该怎么办？ 有什么方法可以不使用pip来安装此软件包？ 我想使用此链接： https : //pypi.python.org/pypi/pdfminer.six/20170720

我对编程很陌生，所以我并不了解。

正如重试错误消息告诉您的那样，这是一个代理问题。 您的点子无法通过代理连接到互联网。

尝试使用pip --proxy url:port pdfminer.six和url:port代理您的代理，例如proxy.example.com:8080 。

如果这不起作用，请尝试使用没有代理的其他Internet连接通过pip安装软件包，或查看此线程 ，其中提供了有关pip和代理的更多答案。
