【问题描述】：

当我尝试安装 Jupiter 时，我得到了错误：

┌─╼ [~]

pkg_resources.DistributionNotFound: The 'pip==9.0.1' distribution was not found and is required by the application

当我执行命令pip --version 时，我得到了什么

pip 9.0.1 from /home/jeremie/Enthought/Canopy_64bit/User/lib/python2.7/site-packages (python 2.7)

我可以做些什么来解决这个问题？

提前致谢！

P.S.我运行的是 Ubuntu 16.10。

【问题讨论】：

你在什么操作系统上运行这个？
@OluwafemiSule 我正在运行 Ubuntu 16.10
不确定是否需要使用sudo 安装python 包。您可能希望在虚拟环境中管理您的包。
The 'pip==7.1.0' distribution was not found and is required by the application的可能重复

标签： python pip

【解决方案1】：

sudo -H pip是系统点子

文件“/usr/local/bin/pip”，

pip --version 是你本地路径上的 pip

来自 /home/jeremie/Enthought/Canopy_64bit/User/lib/python2.7/site-packages (python 2.7) 的 pip 9.0.1

不要使用 sudo
