我在 Windows 10 上使用 Python 3.6。我该怎么办？有什么方法可以在不使用 pip 的情况下安装这个包？我想用这个链接：https://pypi.python.org/pypi/pdfminer.six/20170720

我对编程很陌生，所以我不太了解。

【解决方案1】：

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

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

如果这不起作用，请尝试使用另一个没有代理的 Internet 连接通过 pip 安装软件包，或查看此thread，其中包含有关 pip 和代理的更多答案。
