我在Windows 10上使用Python 3.6。我應該怎麼做？有什麼方法可以在不使用pip的情況下安裝此軟件包？我想用這個鏈接：https://pypi.python.org/pypi/pdfminer.six/20170720

我對編程很新，所以我不太瞭解。

這是一個代理問題，因爲重試錯誤消息告訴你。您的點不通過代理連接到互聯網。

嘗試pip --proxy url:port pdfminer.six與url:port讓您的代理服務器受阻proxy.example.com:8080。

如果這不起作用，請嘗試使用另一個沒有代理的互聯網連接來通過pip安裝軟件包，或者看看這個thread，它有關於點和代理的更多答案。
