How do I build a local copy of the documentation from the doc/en folder?

[enricojr01]

Short summary - I'm trying to build a local html copy of the documentation that can be served up through nginx using a Docker image like so

FROM python:3.8 as builder
RUN ["mkdir", "/pythonsrc"]
WORKDIR "/pythonsrc"
RUN ["git", "clone", "https://github.com/pytest-dev/pytest.git", "."]
WORKDIR "/pythonsrc/doc/en"
RUN ["pip", "install", "-r", "requirements.txt"]
RUN ["make", "html"]

But I get an error I can't make sense of -

 ---> Running in 1852c734a540
Running Sphinx v3.5.4

Configuration error:
There is a programmable error in your configuration file:

Traceback (most recent call last):

    from _pytest import __version__ as version
ModuleNotFoundError: No module named '_pytest'

make: *** [Makefile:20: html] Error 2
The command 'make html' returned a non-zero code: 2

Am I missing a step? Try as I might I can't find anything in the pytest repo or its documentation on how to actually build the documentation itself.

I was wondering if anyone else here has tried and could maybe point me in the right direction?

Hi,

Try tox -e docs (after installing tox of course).

Cheers,

That did the trick! Thank you very much!

(also worth noting it had to be run from the project root, and not from within doc/en)
