Mathematics not working when converting from LaTeX to docx (through markdown) using pandoc

Question

Does anyone have a suggestion as to why I am unable to convert the simple latex file shown below to docx using pandoc (version 1.12.4.2, Compiled with texmath 0.6.6.3, highlighting-kate 0.5.11.1).

\documentclass{article}

\begin{document}

\begin{equation}
  1+1
\end{equation}

\end{document}

The pandoc commands I have used are:

pandoc --from=latex --to=markdown --output=FILE.md FILE.tex
pandoc --from=markdown+tex_math_dollars --to=docx --output=FILE.docx FILE.md

The result from the first command (the markdown file) is a file consisting of a single line: "$$1+1$$". The second command, which is supposed to produce the docx document, is empty.

Answer 1

This turned out to be one of those cases where the strategy "when in doubt re-install" does the trick. I lay the blame on OS-X Yosemite, it has been a "problematic child" since its inception.

Pandoc is dependent on an arsenal of haskell libraries and somewhere in the macports installation "something" must have gone wrong. I therefore uninstalled pandoc and all dependent packages as follows:

usr@cmptr $ sudo port uninstall --follow-dependents pandoc

Note --follow-dependents not --follow-dependencies, the latter is only for people who know what they are doing (read more).

EDIT

The pandoc version from mac Ports is often severely lagging compared the development. The reason for this is probably that the development is happening quite rapidly at the moment; therefore one can consider to install pandoc using the haskell "cabal" repository:

usr@cmptr $ sudo port install cabal
usr@cmptr $ cabal update
usr@cmptr $ cabal install pandoc

Also enable bibliography:

usr@cmptr $ cabal install pandoc-citeproc

And finally enable cross referencing (markdown notation, LaTeX -> Markdown conversion still iffy):

usr@cmptr $ cabal install pandoc-crossref

Add pandoc to $PATH:

usr@cmptr $ export PATH="${PATH}:${HOME}/.cabal/bin/" >> ${HOME}/.bashrc
