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 Traceback (most recent call last): File “c:\users\luuka\anaconda3\envs\wintest\lib\runpy.py”, line 193, in _run_module_as_main “main”, mod_spec) File “c:\users\luuka\anaconda3\envs\wintest\lib\runpy.py”, line 85, in run_code exec(code, run_globals) File "C:\Users\luuka\Anaconda3\envs\wintest\Scripts\jupyter-book.exe_main.py", line 7, in File “c:\users\luuka\anaconda3\envs\wintest\lib\site-packages\click\core.py”, line 829, in call return self.main(args, kwargs) File “c:\users\luuka\anaconda3\envs\wintest\lib\site-packages\click\core.py”, line 782, in main rv = self.invoke(ctx) File “c:\users\luuka\anaconda3\envs\wintest\lib\site-packages\click\core.py”, line 1259, in invoke return process_result(sub_ctx.command.invoke(sub_ctx)) File “c:\users\luuka\anaconda3\envs\wintest\lib\site-packages\click\core.py”, line 1066, in invoke return ctx.invoke(self.callback, ctx.params) File “c:\users\luuka\anaconda3\envs\wintest\lib\site-packages\click\core.py”, line 610, in invoke return callback(args, **kwargs) File "c:\users\luuka\anaconda3\envs\wintest\lib\site-packages\jupyter_book\commands_init.py", line 199, in build 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?

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.

i cloned it and run as instruction and got this error in windows 10: Traceback (most recent call last): File "c:\python38\lib\site-packages\jupyter_book\sphinx.py", line 150, in build_sphinx app.build(force_all, filenames) File "c:\python38\lib\site-packages\sphinx\application.py", line 348, in build self.builder.build_update() File "c:\python38\lib\site-packages\sphinx\builders__init.py", line 297, in build_update self.build(to_build, File "c:\python38\lib\site-packages\sphinx\builders__init__.py", line 311, in build updated_docnames = set(self.read()) File "c:\python38\lib\site-packages\sphinx\builders\init.py", line 382, in read for docs in self.events.emit('env-get-outdated', self.env, added, changed, removed): File "c:\python38\lib\site-packages\sphinx\events.py", line 117, in emit raise ExtensionError(("Handler %r for event %r threw an exception") % sphinx.errors.ExtensionError: Handler <function update_execution_cache at 0x0000016B516A4EE0> for event 'env-get-outdated' threw an exception (exception: Notebook does not appear to be JSON: '{\n "cells": [\n {\n "cell_type": "c...)
