I'm working thorough Hadley's package book (using Rstudio 1.1.383) and cannot build a simple package - just the default template of a new package created via the wizard.
Both devtools::build() or using the menu to "Build Source Package" both result in the error:
Error in process_initialize(self, private, command, args, stdout, stderr, :
object 'c_callr_exec' not found
Installing seems to work fine i.e. the function hello() works. Am I missing something obvious?
