找不到Pandoc版本1.12.3

Question

By using sudo R, I can't find in my shinyApp the pandoc and I get this message.

Warning: Error in : pandoc version 1.12.3 or higher is required and was not found (see the help page ?rmarkdown::pandoc_available).

When I do:

rmarkdown::pandoc_available()

I get

FALSE

When I do:

pandoc -v

I get

pandoc 1.17.2
...

But when I do

Sys.getenv("RSTUDIO_PANDOC")

I get

""

I don't have Rstudio installed. Do I need to have it installed in order to find the pandoc? I run a Centos 7 x64-bit server and I was hoping I could bypass the rstudio installation, since it does not provide anything to my services. If not, how can I define the env of the pandoc?

Answer 1

Although this is not a straightforward answer, what I ended up doing, was installing rstudio-server instead, so that I can get a much more lightweight solution to solve my problem. I did not find any other way of bypassing this issue. I am open to suggestions if something comes up.
