How to install pandoc-crossref

Question

I would like cross-reference figures in rMarkdown, and pandoc-crossref seems to be a common solution (see here). The instructions on pandoc's Github page say:

Assuming you already installed Haskell platform, you can install pandoc-crossref with cabal:
cabal update
cabal install pandoc-crossref

So I installed Haskell from here. However, when I try to run cabal update in the GHCi terminal, I just get an error:

So, how do I install pandoc-crossref?

All cabal commands should be run from the command line, not from GHCi. — user2407038, Dec 01 '17 at 15:59
Please don't paste images of problems, just the text will do. — Thomas M. DuBuisson, Dec 01 '17 at 16:37
@ThomasM.DuBuisson how was I to know that the error message itself was not relevant here? — filups21, Dec 01 '17 at 16:49
The `pandoc-citeproc` binary is shipped with pandoc. Best to save yourself some trouble and just download it from the [download page](https://github.com/jgm/pandoc/releases/). — tarleb, Dec 01 '17 at 17:16
@filups21 I was suggesting you use text instead of images, not omit the information entirely. Pictures of code and errors are usually less helpful than copy/paste-able blocks of text. — Thomas M. DuBuisson, Dec 01 '17 at 17:59

cabal is a binary from the cabal-install package and not a Haskell function. You should execute programs from a command line and not within GHCi. It looks like you are using windows so there might be some steps to find the program but once you do you should be able to call it directly.
