I am working in RStudio Cloud and am unable to knit markdowns, with this resulting message:

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

To fix this, I installed "installr" and attempted to install the pandoc software through this package, but received the following error:

Error in system("ifconfig", intern = TRUE) : error in running command

The pandoc_available command resulted in this error:

pandoc_available(version = NULL, error = FALSE)
Error in pandoc_available(version = NULL, error = FALSE) : 
  could not find function "pandoc_available"

pandoc_available()
Error in pandoc_available() : could not find function "pandoc_available"

Is there a way to get RStudio to successfully recognize and install pandoc version 1.12.3? For context, I was able to knit markdowns until just recently. Was there an update to pandoc?

Thanks!
