pandoc document conversion failed with error 2

Question

when I knit HTML in R studio, I get this:

"C:/Users/Susan/ANACON~1/Scripts/pandoc" +RTS -K512m -RTS lesson3_student.utf8.md --to html --from markdown+autolink_bare_uris+ascii_identifiers+tex_math_single_backslash --output lesson3_student.html --smart --email-obfuscation none --self-contained --standalone --section-divs --template "C:\Users\Susan\Documents\R\win-library\3.3\rmarkdown\rmd\h\default.html" --no-highlight --variable highlightjs=1 --variable "theme:bootstrap" --include-in-header "C:\Users\Susan\AppData\Local\Temp\RtmpaUaaRx\rmarkdown-str3cf45da21737.html" --mathjax --variable "mathjax-url:https://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS-MML_HTMLorMML" output file: lesson3_student.knit.md

unrecognized option `--smart' Try pandoc.exe --help for more information. Error: pandoc document conversion failed with error 2 In addition: Warning message: running command '"C:/Users/Susan/ANACON~1/Scripts/pandoc" +RTS -K512m -RTS lesson3_student.utf8.md --to html --from markdown+autolink_bare_uris+ascii_identifiers+tex_math_single_backslash --output lesson3_student.html --smart --email-obfuscation none --self-contained --standalone --section-divs --template "C:\Users\Susan\Documents\R\win-library\3.3\rmarkdown\rmd\h\default.html" --no-highlight --variable highlightjs=1 --variable "theme:bootstrap" --include-in-header "C:\Users\Susan\AppData\Local\Temp\RtmpaUaaRx\rmarkdown-str3cf45da21737.html" --mathjax --variable "mathjax-url:https://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS-MML_HTMLorMML"' had status 2 Execution halted

Can someone give me an idea what went wrong and how to fix it?

Thank you

I'm guessing the version of pandoc being picked up in your case comes without support for the --smart flag. Presumedly, you have an Anaconda installation or something similar, and that is providing a version of pandoc that doesn't support that flag? — Kevin Ushey

Today I had the same problem. I fixed it by setting the smart option to false, as described here.

   output:
     html_document: 
       smart: false

It seems that --smart is no longer supported in the newest pandoc version (1.19.2.1), even though it should be should be; see discusion on the RStudio forum
