render not found

[data-al]

After installing the latest rmarkdown package i have this issue trying to knit the default or any other .rmd :

[1] 127
Warning message:
In system(paste0("rmarkdown::render '", input, "'")) :
  'rmarkdown::render' not found

No document is produced. I'm guessing it's some kind of problem with finding the function of the package ? Any guidance is appreciated

I am getting the same issue. It all started when I tried to install gt package. I reinstalled all the packages. But that did not fix anything. Everything worked after installing fastmap separately and I have no idea why that worked.

rmarkdown uses some packages that depends on fastmap

> pak::pkg_deps_explain("rmarkdown", "fastmap")
v Updated metadata database: 3.97 MB in 5 files.                          
v Updating metadata database ... done                                     
rmarkdown -> htmltools -> fastmap                                          
rmarkdown -> jquerylib -> htmltools -> fastmap

So if there was an issue with fastmap installation, then those packages wouldn't load, and rmarkdown etiher.

Anyway, I don't think this was related to this issue here. Glad you found the fix !

Can confirm that I too had this error which was fixed after I installed tinytex. Error:

Warning message: In system(paste0("rmarkdown::render \"", input, "\"")) : 'rmarkdown::render' not found

Details about my setup:

R version 4.0.5 (2021-03-31) -- "Shake and Throw"
Platform: x86_64-w64-mingw32/x64 (64-bit)
RStudio Version 1.4.1106

I also met this issue. It happened when I'm trying to run library(ggplot2) when I had mistakenly uninstalled one of the needed package rlang. After reinstalling that package, the issue was sovled. Hopefully my experience may help.

Hi all, sorry to revive this from August. I had the same issue today using R 4.1.0 and RStudio 1.4.1717 (I'm on a managed software catalog so cannot update). Neither installing tinytex nor a fresh install of rmarkdown helped, but installing a newer version of xfun solved the issue. I found this out only because I tried "Knit with parameters" and it told me the xfun version wasn't high enough:

Error in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]) : namespace ‘xfun’ 0.30 is being loaded, but >= 0.34 is required

Thanks for sharing this - I did not know this could be a side effect of this minimum requirement issue.
