Jupyter Notebook 安装

本节介绍 Jupyter Notebook 的安装，Jupyter 是从 IPython 衍生出来的一个项目，因此使用 pip 即可安装。

安装​

$ sudo pip3 install jupyter

如果安装过程中出现如下错误，通常是因为之前通过 apt 安装了 ipython3。

Cannot uninstall 'ipython'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.

执行下面命令卸载 ipython3 后重新执行 pip 安装 jupyter 即可。

$ sudo apt-get remove ipython3

使用​

执行 jupyter notebook 启动

$ jupyter notebook

[I 19:36:12.020 NotebookApp] 启动notebooks 在本地路径: /home/rudy/workspace_hd/Python_Learning/14th_week

这时候会自动打开浏览器，可以看到 Jupyter Notebook 的页面如下。

点击 “新建”，选择 Python3，在打开的单元格中就可以编写 Python 代码啦！
