Hey anyone,

I'm using htmldoc-0.2.3 on ruby 1.8.7 and I'm struggling to get it

------
require 'rubygems'

  pdf.set_option :outfile, "/tmp/outfile.pdf"

Error:

/Users/dandan/.rvm/gems/ruby-1.8.7-p302/gems/htmldoc-0.2.3/lib/
htmldoc.rb:182:in `execute': Invalid program path: htmldoc

htmldoc.rb:154:in `generate'
  from pdf.rb:17

To attempt to fix this I added
PDF::HTMLDoc.program_path = '/Users/dandan/.rvm/gems/ruby-1.8.7-p302/
gems/htmldoc-0.2.3'

Running the script again I get the output from pdf.result[:output]:
sh: /Users/dandan/.rvm/gems/ruby-1.8.7-p302/gems/htmldoc-0.2.3: is a
directory

Has anyone else experienced this problem and has a solution. I'm
guessing I'm giving the wrong program path but I'm not sure which path
I should be giving.

Thanks abundantly for any help!

Dan,

Step on is to confirm that you have the htmldoc executable installed.
`which htmldoc` should return the location of the binary. The gem only
wraps calls to the executable, so doing point it back to itself.

If you have htmldoc installed, then check path issues.
