Error: Terminal shell path "R" is a directory

[notZaki]

Running any command, such as Bookdown: Serve Book results in an error message saying that the shell path is a directory.

This occurs on Linux (Solus OS), although I've used the extension on a different computer with the same OS and didn't encounter this problem.

Workaround:
Locate the R executable with running the following in a terminal

which R

and note down the returned path.
Then:

open vscode -> Ctrl Shit P -> Preferences: Open Settings (JSON)

and add the following as a new line:

"Bookdown.R" = "/usr/bin/R"

where the "/usr/bin/R" part should match whatever was returned by which R earlier.
