Build of 0.15.1-3 fails on: Building HTML documentation with Sphinx

[3eka]

Hi,

trying to build mydumper on OpenIndiana, GCC 12, and python-3.9:

...
[ 97%] Building HTML documentation with Sphinx
Traceback (most recent call last):
  File "/usr/bin/sphinx-build", line 5, in <module>
    from sphinx.cmd.build import main
  File "/usr/lib/python3.9/site-packages/sphinx/cmd/build.py", line 25, in <module>

    from jinja2 import Environment, environmentfilter
ImportError: cannot import name 'environmentfilter' from 'jinja2' (/usr/lib/python3.9/vendor-packages/jinja2/__init__.py)
gmake[2]: *** [docs/CMakeFiles/doc_html.dir/build.make:71: docs/CMakeFiles/doc_html] Error 1
gmake[1]: *** [CMakeFiles/Makefile2:238: docs/CMakeFiles/doc_html.dir/all] Error 2
gmake: *** [Makefile:136: all] Error 2

Looking at the error, seems that environmentfilter is missing in jinja2... Here versions:

:; pkg list jinja2 sphinx
NAME (PUBLISHER)                                  VERSION                    IFO
library/python/jinja2                             3.1.2-2023.0.0.0           i--
library/python/sphinx                             7.2.6-2023.0.0.0           i--

So: how I can pass building WITH HTML docs, using Sphinx (I know I can use -DBUILD_DOCS=OFF to avoid it...)?

Thanks for this excellent tool.
Regards.

Hi @3eka
I was trying to understand the issue and I found readthedocs/readthedocs.org#9038 and then I jumped to readthedocs/readthedocs.org#9037 (comment).
I might need to install sphinx to build the documentation and find this kind of issues.
