Does not create subdirectories

[Janek]

I keep getting errors like this:

{ stdout: '',
  stderr:
   'pandoc: Markdown/Software-Challenge-:-Styleguide-/-allgemeine-Richtlinien.md: openFile: does not exist (No such file or directory)\n',
  status: 1 }
Reading : Markdown/Software-Challenge-:-Styleguide-/-allgemeine-Richtlinien.md
fs.js:115
    throw err;
    ^

Error: ENOENT: no such file or directory, open 'Markdown/Software-Challenge-:-Styleguide-/-allgemeine-Richtlinien.md'

However, as soon as I create that directory, everything runs fine, so apparently this program fails to create subdirectories when necessary.
