I'm looking for a way to install the development dependencies for a package, and running something like local_install_dev_deps(dependencies = c("config/needs/website")) seems to give me an error.

> pak::local_install_dev_deps(dependencies = c("config/needs/website"))
Error: 
! error in pak subprocess
Caused by error: 
! Could not solve package dependencies:
* deps::/workspaces/prqlr:
  * Can't install dependency pkgdown
  * Can't install dependency extendr/rextendr
Type .Last.error to see the more details.

I thought it might be due to referencing packages on GitHub, but the same error occurred when I left the CRAN package alone.
