我最近將 Ubuntu 伺服器從 15.04 升級到 16.04 LTS。在此過程中，安裝了Python 3.5。然而，由於某種原因，它附帶的 pip3 版本顯然想使用 python 3.4，而不是 python 3.5。
這是我看到的錯誤：
-bash：/usr/local/bin/pip3：/usr/bin/python3.4：錯誤的解釋器：沒有這樣的檔案或目錄
如何安裝適當版本的 pip 來配合我的 python 3.5 安裝？
以下是我安裝的 python 軟體包（透過 找到sudo apt list --installed | grep python）：

答案1
我下載了get-pip.py腳本，並使用 python3.5 運行它。這樣做似乎就澄清了事情。
