Adding a vignette stops devtools :: check () from working

I am writing a personal package with a link to the Hadley guide . However, adding a minimal vignette using devtools::use_vignette() seems to violate devtools::check() .

When I try to run check() , I get one error:

 file 'C:/path/temp/package/DESCRIPTION' is not in valid DCF format

and one warning:

 In read.dcf(dfile, keep.white = .keep_white_description_fields) : cannot open compressed file 'C:/path/temp/package/DESCRIPTION', probable reason 'Permission denied'

I can successfully run devtools::check() if I delete the vignettes folder and devtools::build_vignettes() works fine.

Edited to add: I wondered if this was a problem when trying to check from a network location, but I copied the project to C:\R\package_name and it still returns the same error.

Curiously, this seems to be machine dependent, as I get the above error on my working machine, but not on my personal laptop. The working machine is win7, a personal victory.
