errors when running make command

[sayanee]

thanks for clearing up that the mobi making was wrong in #10 👍

i had the following error towards the end of the make command:

1% Converting input to HTML...

The error says the ePub metadata file (content.opf) is missing a spine; without that, we don't know the order of the contents, and so we can't build a MOBI. If you flip open bin/opf and lib/opf, you'll see where that should be introduced: we take the path of each HTML chapter in the volume, and with each one choose an identifier, appending an XML element describing it to the spine (preserving order.) The identifier is linked to a file by an entry in the manifest, added in about the same way.

It's supposed to end up including something like:

<spine>
<itemref idref="III_01html"/><itemref idref="III_02html"/><itemref idref="III_03html"/><itemref idref="III_04html"/><itemref idref="III_05html"/><itemref idref="III_06html"/><itemref idref="III_07html"/><itemref idref="III_08html"/><itemref idref="III_09html"/><itemref idref="III_10html"/><itemref idref="III_11html"/><itemref idref="III_12html"/><itemref idref="III_13html"/><itemref idref="III_14html"/><itemref idref="III_15html"/><itemref idref="III_16html"/><itemref idref="III_17html"/><itemref idref="III_18html"/><itemref idref="III_19html"/><itemref idref="III_20html"/><itemref idref="III_21html"/><itemref idref="III_22html"/><itemref idref="III_90html"/><itemref idref="III_91html"/><itemref idref="III_92html"/>
</spine>

That might be failing because you're missing the library we use for working with XML. Have you run gem install nokogiri? I should add a Gemfile describing the dependencies of the Ruby stuff..

I'm really glad someone other than me is trying to use this. 😄

Cool:

git pull
make clean; bundle && make

[eshellman]

as a ruby newbie I can report that bundler is another dependency
