Rmarkdown not rendering .rmd to pdf, pandoc error 2

[mai-nguyen]

Hi,

I was trying to render an Rmarkdown file to pdf using beaverdown and got the following error:

output file: thesis.knit.md
--chapters has been removed. Use --top-level-division=chapter instead. Try pandoc.exe --help for more information. Error: pandoc document
conversion failed with error 2 In addition: Warning message: In
has_crop_tools() : Tool(s) not installed or not in PATH: pdfcrop,
ghostcript
-> As a result, figure cropping will be disabled. Execution halted

I'm using:

• Pandoc 2.11.4
• MiKTeX 21.1

I haven't done anything besides rendering the template. Could this have anything to do with my current version of pandoc?

Any suggestion would be greatly appreciated.

Hi @mai-nguyen,

I haven't done anything besides rendering the template. Could this have anything to do with my current version of pandoc?

Part of this is a symptom of the fact that I have not updated this since I graduated four years ago (and didn't add automated testing). Since then, pandoc has incurred a major version change (that broke a lot of things), and {bookdown} (which coordinates everything) also has gone through nearly 19 versions.

The error is also saying that you do not have ghostscript or pdfcrop installed.

I'll see what I can do to update things for pandoc version 2 this weekend.

That would be wonderful. Thank you so much!
