[Rahuketu86]

I am unable to build a jupyter book with following error /home/ubuntu/anaconda3/envs/testjb/lib/python3.9/site-packages/sphinxcontrib/bibtex/init.py

Steps taken :

1. Created a new conda environment
2. pip install -r requirements.txt

1. jb create tbook
2. jb build tbook
3. (Others) Tried adding bibtex_bibfiles in _config.yml with no success

I encountered the same problem in running Github Actions to build my site today, though versions are different.

Same as @spring-haru here:

I got the ExtensionError("You must configure the bibtex_bibfiles setting") in gh-actions, using ubuntu-latest and Python 3.7.9.

[choldgraf]

Argg - this is because sphinx-bibtex just released a major version that's incompatible. I've pinned sphinxcontrib-bibtex to the 1.0 version on the master branch, and we'll get that into the next JB release. In the meantime just ensure that you have sphinxcontrib-bibtex 1.0 👍

@choldgraf correct! I've just tried it, the sphinxcontrib-bibtex version 1.0 works, 2.0 doesn't (this is installed by default).

For the rest of people in the thread:

just add sphinxcontrib-bibtex==1.0.0 in your requirements.txt

Edit: sphinxcontrib-bibtex<2.0.0 probably more correct

[SimonBiggs]

just add sphinxcontrib-bibtex==1.0.0 in your requirements.txt

And for those of us using something like poetry, the following is key:

sphinxcontrib-bibtex = {version = "<2.0.0"} 

[g4brielvs]

I am having the same issue. Adding sphinxcontrib-bibtex<2.0.0 to requirements.txt should fix it for the moment.

[Rahuketu86]

Thank you for quick resolution. It seems to be working with pinning to version 1.0.0

[atantet]

I'm new to Jupyter Book, but maybe an entry could be added to the FAQ for new users who encounter this problem ? A simple quick and dirty fix without having to handle versions with pip is to add

sphinx:
  config:
    bibtex_bibfiles: "your_reference_file.bib"

in the _config.yml file.
