Question

我写了一个很长的IPython笔记本，需要将其转换为PDF才能分发。我已阅读this thread，但解决方案对我不起作用。

我尝试了以下内容：

如果我在浏览器中使用“打印”按钮，则会显示所有IPython菜单等等，我不能接受。
如果我使用IPython菜单中的“打印预览”，则不会渲染任何LaTeX方程式。它们仍然只是LaTeX代码。
如果我使用ipython nbconvert --to latex --post pdf myfile.ipynb，我会获得FileNotFoundError。跟踪如下：

[NbConvertApp] Using existing profile dir: 'C:\\Users\\blokeley\\.ipython\\profile_default'
[NbConvertApp] Converting notebook myfile.ipynb to latex
[NbConvertApp] Support files will be in myfile_files\

[NbConvertApp] Writing 72246 bytes to myfile.tex

or send an email to the mailing list at ipython-dev@scipy.org

You can print a more detailed traceback right now with "%tb", or use "%debug"
to interactively debug it.

您的问题是您的计算机上未安装LaTeX。当subprocess尝试呼叫pdflatex myfile.tex时，它会失败，因为它无法找到pdflatex。

虽然您可以在不需要LaTeX的情况下从IPython笔记本创建.tex文件，但这些只是包含LaTeX代码的文件。要编译它们以创建PDF，您需要一个版本的LaTeX。

在Windows上安装LaTeX并不困难，MiKTeX是一种可能的安装。
