python无法在Windows10上安装pdfminer.six

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？我要使用此链接：https://pypi.python.org/pypi/pdfminer.six/20170720

我对编程很陌生,所以我并不了解.

解决方法:

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.

尝试将pip –proxy url：port pdfminer.six与url：port用作代理,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thread,其中提供了有关pip和代理的更多答案.
