Building mini-book

[luukalt]

Following the steps from demo book on https://jupyterbook.org/intro.html

When running the following command (in anaconda prompt on Windows 10 PC):

(wintest) C:\Users\luuka\quantecon-mini-example>jupyter-book build ./mini_book

It returns the following output and error:

Running Jupyter-Book v0.8.3

ValueError: max() arg is an empty sequence

Does anybody have an idea what I could do to fix this?

Thanks in advance.

I faced the same issue when running the demo. I fixed it by creating a dummy index.html in _build/html/, and then running jupyter-book build (name of book directory). Once I got that to work, I then removed the dummy file and reran jupyter-book build (book directory) to successfully load the book.
