Hi Tim,
Thanks for your reporting about devguide.
I've updated the `pip install` line.
For latex, this error is indicated in your error log.
! Package inputenc Error: Unicode char \\u8:\xc3\xa4nh not set up for use with LaTeX.
See the inputenc package documentation for explanation.
I guess your latex environment doesn't have enough latex package (or something wrong...?).
Actually I can't say what is correct latex environment for sphinx.
Usually I've installed "TeXLive 201x" to test with latex.
