Don't know how to build task ''

[mariochavez]

Just running rake or rake epub I got the following error, I'm not sure how to fix it.

I did clone quarto repo and installed gem from my local copy, gem un Rubygems seems to be old code.

rake aborted!

[saturnflyer]

Just realized this is a dup of #18

[saturnflyer]

Leaving comments here since this has my original stack trace and #18 doesn't.

I am able to get a new error when I remove main.bitmap_cover_image from the list of dependencies for pristine_epub at https://github.com/avdi/quarto/blob/master/lib/quarto/pandoc_epub.rb#L71

Here is the error:

I am unsure of how to structure the files. Right now I merely created a ch1.md in the root of my project. While debugging I created an images directory with 2 blank files: cover-large.png and cover.svg. These files seemed to have no effect on the output.

Edit:
I don't have pandoc installed, apparently. I'm working on that and will update these details as I debug.

[avdi]

Are the tests passing for you? I pushed a bunch of updates to get the tests passing again.

[saturnflyer]

Tests fail for me, but I'm working my way through ensuring that I have all the dependencies.

[avdi]

If a README guide to installing all the deps happened to fall out of that
process, I would be very happy :-)

[saturnflyer]

that is my intent

[robmiller]

I've been able to fix the problem I was having with the specs in issue #20, but I'm still getting the don't know how to build task "" when running any Quarto rake task; I also get this error in the specs, e.g.:
