Hi all,
I was trying to test Jupyter Books to convert my notebooks and my .md files into a nice readable piece, but I am failing on installing it, and so far I havent found why.
I am following the steps provided in https://jupyterbook.org/intro.html but I cant execute this command jupyter-book build ./mini_book. It always give me an error related with encoding problems, and to modules e.g. matplotlib. This last error I dont understand because I installed an environment that has all these packages before invoking the book build command.
This is very frustating because I am only following the steps they propose with a dummy test that does not work.
If you can give some hints of what is maybe happening it will be of great help!
So this is what appears after I run the command.
Basically a lot of warnings and an error with Sphinx .
I can also upload a Bug report issue to the Github repo, but if you have an idea , it will much better.
Thanks!
$ jupyter-book build ./mini_book

question 1: Yes , I checked , and it is where the problems with the modules start to appear:

It should be there because I cloned the original repository…
@Leila it seems your bug report set in motion a chain of events that landed on my desk. So it seems that my prior inaction was one of the reasons of the bug that you encountered
I am also experiencing problems with building the mini-book.
Similar to Leila, I also started with the demo book from Jupyter Book.
When I run the command (in anaconda prompt):
Running Jupyter-Book v0.8.3
Traceback (most recent call last):

build_modified = max([os.stat(ii).st_mtime for ii in build_files])
ValueError: max() arg is an empty sequence
Does anybody have an idea what I could do to fix this?
Let’s see if I can make sense of it. The line that is run checks when the file was last modified out of build_files, and then the function max complains that it’s called on an empty sequence (you can reproduce the same error by calling max([]) with an empty list as an argument.
Given that the variable name is build_files, it seems that you’re trying to build an empty jupyter book, could that be the case? Does the mini_book folder contain files to be built?
When I try to build this book it gives me the same error as before.
I believe this example contains build files, so maybe it is a windows issue (I also tried on another windows PC -> same error).
Look at this 
Here a link to the issue where all guidelines are described for Windows :
