(Resend: Sorry for the dup. I forgot to include the maintainers, and I had the LKML
address wrong.)
I was trying to set up my machine to do some documentation work,
and I had some problems with the sphinx install. I figured out how to work
around the issue, but I have a question about how to add the information
to scripts/sphinx-pre-install (or whether it should go somewhere else).
Detailed messages below, but the TLl;DR is that I got the message:
-------
You should run:
sudo apt-get install dvipng fonts-noto-cjk latexmk librsvg2-bin texlive-xetex
/usr/bin/virtualenv sphinx_1.7.9
. sphinx_1.7.9/bin/activate
pip install -r ./Documentation/sphinx/requirements.txt
...
------
The pip install step didn't work, and I found that I needed to have everything
based on python3 instead. When I replaced:
/usr/bin/virtualenv sphinx_1.7.9
with
/usr/bin/virtualenv -p python3 sphinx_1.7.9
everything worked.
This message is coming from scripts/sphinx-pre-install (I believe on line 708).
Should I go ahead and submit a patch to add '-p python3' to that line?
Are there any downsides to enforcing that the virtualenv used for the
documentation build use python3 only?
Thanks,

Gory details:
I'm running on a machine with Ubuntu 16.04, and I have both python2 and
python3 installed (with /usr/bin/python linked to python2.7).
When I tried to do:
$ make htmldocs
I got the following messages:
...
You should run:
sudo apt-get install dvipng fonts-noto-cjk latexmk librsvg2-bin texlive-xetex
/usr/bin/virtualenv sphinx_1.7.9
. sphinx_1.7.9/bin/activate
pip install -r ./Documentation/sphinx/requirements.txt
If you want to exit the virtualenv, you can use:
deactivate
---
Following these instructions, at the 'pip install' step, I got:
$ pip install -r ./Documentation/sphinx/requirements.txt
