Question

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。我猜这里的问题是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，我收到此错误：

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，之后我收到以下错误：

我也尝试过以这种方式设置我的代理：

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jupyter notebook安装pip。

请不要将此问题标记为重复，因为我一直在寻找解决方案，但这些问题都不起作用。

有人可以帮忙吗？

适用于Ubuntu 14.04

我使用anaconda解决了安装问题。我在this链接中给出了说明。我无法解决升级pip的问题。安装jupyter notebook的步骤如下：

第1步（请参阅here）

首先，我们使用anaconda

安装wget

32位版本

的wget https://3230d63b5fc54e62148e-c95ac804525aac4b6dba79b00b39d1d3.ssl.cf1.rackcdn.com/Anaconda-2.3.0-Linux-x86.sh

64位版本

的wget https://3230d63b5fc54e62148e-c95ac804525aac4b6dba79b00b39d1d3.ssl.cf1.rackcdn.com/Anaconda-2.3.0-Linux-x86_64.sh

第2步

下载结束后：

32位版本

bash Anaconda-2.3.0-Linux-x86.sh
64位版本

bash Anaconda-2.3.0-Linux-x86_64.sh

下载anaconda后，打开terminal并输入以下命令：

$ sudo gedit ~/.profile

在文件的末尾添加给定的行：

export PATH=~/anaconda2/bin:$PATH

第3步

添加行后保存文件。打开一个新的terminal，然后转到已下载anaconda的目录。

$ cd anaconda2/bin
~/anaconda2/bin$ source activate
(root):~/anaconda2/bin$ jupyter notebook

jupyter notebook将在浏览器中打开。
