【问题描述】：
我正在尝试安装jupyter notebook，但由于某些原因我无法安装它。我查看了几个链接，例如 this 和 this，但它对我没有帮助。我猜这里的问题在于pip 的安装。当我检查pip 的版本时，我得到以下结果：
shaloin@shaolin-Inspiron-3543:~$ pip --version
pip 1.5.4 from /usr/lib/python2.7/dist-packages (python 2.7)
但是当我尝试升级pip 的版本时，我收到了这个错误：
shaloin@shaolin-Inspiron-3543:~$ sudo pip install --upgrade pip
Cannot fetch index base URL https://pypi.python.org/simple/
Could not find any downloads that satisfy the requirement pip in /usr/lib/python2.7/dist-packages
Downloading/unpacking pip
Cleaning up...
No distributions at all found for pip in /usr/lib/python2.7/dist-packages
Storing debug log for failure in /home/shaloin/.pip/pip.log
所以，我搜索了错误，我知道如果你在代理后面，你应该尝试以下命令：
sudo pip --proxy [NITS:abcde@]172.16.30.20:8080 install jupyter
其中NITS 是用户名abcde 是密码，proxy server = 172.16.30.20 和password=8080，之后出现以下错误：

我也尝试过以这种方式设置代理：
set http_proxy=http://username:password@proxyAddress:port
set https_proxy=https://username:password@proxyAddress:port
但这些都不适用于使用pip 安装jupyter notebook。
请不要将此问题标记为重复，因为我一直在寻找解决方案，但没有一个有效。
有人可以帮忙吗？
【问题讨论】：
-
您的
pip太旧，无法自行升级。试试get-pip.py。 -
我是新手，没有太多专业知识，所以我应该运行这个命令
sudo pip get-pip.py -
没有。您需要下载该文件，然后将目录更改为该文件所在的位置，然后运行
sudo python get-pip.py。 -
使用 Python 虚拟环境。使用
pip将软件包安装/升级到系统 Python 是一个坏主意，因为您可能会破坏软件包的操作系统版本。
