Jupyter Notebook导出PDF

大家在用Jupyter Notebook编写交互程序时，有时会想把当前的操作流程以及结果保存下来，Jupyter提供了多种文件导出方式：

jupyter notebook文件导出
可以看到Jupyter支持将交互界面导出成html、md、PDF等多种格式，而我个人比较喜欢的是pdf格式。
但是在点击Download as -> PDF via LaTex(.pdf)时，会发现弹出界面报错了，错误信息会告诉你，想要导出pdf，需要安装Tex组件，并且很贴心的把安装说明网址告诉你：

https://nbconvert.readthedocs.io/en/latest/install.html#installing-tex

接下来就是安装这个组件了，打开网页，可以看到在ubuntu环境中，其实是安装一个叫Tex Live的组件，安装命令为：

apt-get install texlive-xetex

安装完成之后，再点击导出pdf，结果会发现仍然是报错，这次的错误信息很复杂，大至意思是少了什么字体文件。

再去google吧，找到如下命令：

apt-get install texlive-fonts-recommended
apt-get install cm-super

尝试一下，仍然报错，再次google，这次成功了，命令如下：

apt-get install texlive-full

看一看导出效果，感觉不是很好看，不过能用了
