Content block expected for the "raw" directive; none found.

Hello,

while writing content for Nikola (static-site-generator) I've a need to
display counter for downloaded links and first of all tried with 'raw'
directive as in the 2nd definition, but I get: "Content block expected
for the "raw" directive; none found."

Then I found some workaround to use it inline, like in the 1st
definition and that works, but wonder what is wrong with the 2nd
example?

.. raw:: html
   <script>ccount_display('2');</script>

Any hint?
