Re: [Jython-users] Cannot Install Sphinx1.3.3 Into Jython2.7.0

[Jim B. <jim...@py...>]

David,

First, it works for me, running against 2.7.1 master. So let's see what we
have here. I think you have two separate issues:

1. Installing Jython, with pip support. We have been making progress on
updating various aspects of Jython 2.7.1 master so that it supports latest
pip/setuptools. (Although I think it would work with 2.7.0 final.) But to
me, your problems look more of an issue with the Jython installer (see
http://bugs.jython.org/issue2346). I would check the following

$JAVA_HOME/bin/java -version

If that test above doesn't work, you have a JAVA_HOME set so that it does
NOT works with Jython 2.7. ( FWIW, unsetting JAVA_HOME usually is the
easiest choice.)

2. Using Sphinx. We have some broken unit tests in Sphinx (
http://bugs.jython.org/issue2288), but I don't think these really matter
for Sphinx users; instead they are more useful for Jython developers to
identify good edge cases.

So for my realistic test case, I tried running Sphinx on Jython against the
source of the Jython book, https://github.com/jython/book. After setting up
a minimal conf.py, that worked just fine. (Note we will still need to
translate some of the directives in the concurrency chapter I wrote, but
that also occurs with http://jython.readthedocs.org/en/latest/, which
probably uses CPython to run Sphinx.)
