昨天我試圖用pip安裝一些python軟件包，但它不起作用。pip無法與pypi服務器建立安全連接

我一直在尋找一個在互聯網上沒有成功的答案。 2012年的很多答案都表明要降級，但那個麻煩的bug從那以後就被修復了。
[email protected]:~$ pip -V
pip 1.5.4 from /usr/lib/python2.7/dist-packages (python 2.7)
有些人有他們的python解釋器的問題，但它似乎很好地連接到服務器。

作爲附加信息，我在幾個星期前做了一次全新的初級安裝。這發生在所有軟件包中。我通過apt安裝了所有東西，所以這似乎有任何想法？
更新 繼@andersson的建議後，我嘗試安裝pip的最新版本。然後這掏出
