How to troubleshoot Error: Could not find package root?

Question

I am running the command: devtools::use_testthat()

and I get the error:

Error: Could not find package root.

Why this happens?

Answer 1

My problem was very similar, but running devtools::document(setwd(...)). The only thing that worked for me:

1. I copied the DESCRIPTION file from another package (https://github.com/filipezabala/voice);
2. I ran devtools::document(setwd(...)) again;
3. After that, I edited the DESCRIPTION file and ran again devtools::document(setwd(...)).

Answer 2

devtools appears now to require the user to setwd("~/path/to/package"), even if functions like devtools::release() have the pkg= parameter set correctly.
