Jupyter笔记本添加扩展模块

访问github打不开，还带偶尔出问题的，这么脆弱，耽误事情，不想好好用这个了，用什么呢？

1.安装步骤：

Step1：确定是已经安装好anaconda

Step2：要在Mac终端下运行，如何找到终端（启动台-其他-终端）

Step3：先安装nbextensions依次输入运行下面代码：

pip install jupyter_contrib_nbextensions

jupyter contrib nbextension install --user

Step4：再安装nbextensions_configurator,依次输入运行以下代码：

pip install jupyter_nbextensions_configurator

jupyter nbextensions_configurator enable --user

Step5：安装完成后，关终端，启动anaconda中的jupyter notebook,在主页中，可以看见Nbextensions标签页，选中Hinterland 就能使用代码补全了。

 

2.安装总是报错，按网上的安装总是报错：

(Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'ConnectTimeoutError(<pip._vendor.urllib3.connection.VerifiedHTTPSConnection object at 0x10339bf98>, 'Connection to pypi.org timed out. (connect timeout=15)')': /simple/jupyter-contrib-nbextensions/

 

 3..解决方案：

分析原因:连接超时，下载不了安装包

解决方法：解决办法：pip install xxx -i http://pypi.douban.com/simple --trusted-host pypi.douban.com（其中的xxx是你需要下载的库，根据自己实际需求更改）

 

4.设置需要的功能

Table of Content是(20)：根据标题生成目录；

Hinterland：可以让你每敲完一个键，就出现下拉菜单，可以直接选中你需要的词汇。：可以让你每敲完一个键，就出现下拉菜单，可以直接选中你需要的词汇。

Snippets：在工具栏里加了一个下拉菜单，可以非常方便的直接插入代码段，完全不用手动敲。
