如何更新pip3子版本？
如何更新pip3子版本？
提问于 2017-05-26 13:56:16
我最近将我的Ubuntu服务器从15.04升级到16.04 LTS。在此过程中，安装了Python3.5。然而，它附带的pip3版本显然出于某种原因而不想使用python3.5，所以想使用python3.4。
下面是我看到的错误：
-bash: /usr/local/bin/pip3 3: /usr/bin/python3.4:糟糕的解释器:没有这样的文件或目录
如何安装适当版本的pip来使用python3.5安装？
下面是我安装的python包(通过sudo apt list --installed | grep python找到的)：

我下载了get-pip.py脚本，并使用python3.5运行它。这样做似乎能澄清问题。
