What happens if you run devtools::load_all()?

(Please don't include session info unless it's explicitly asked for, or you've used reprex::reprex(..., si = TRUE) to hide it away. I've deleted it from your issue to avoid cluttering up the discussion)

[jeffwong]

Everything passes. I also have some Rcpp code in my package, along with a configure.ac, is that what the error is referring to?

[jeffwong]

I'm trying to find this function pkgbuild::compile_dll but am unable to locate it. There doesn't seem to be a package called pkgbuild. Same with pkgload, it is in the DESCRIPTION under import, but I cannot find it anywhere

[hadley]

http://github.com/r-lib/pkgload - you must have installed the dev version of devtools. You might want to switch back to the CRAN version.

[jeffwong]

I reinstalled devtools from CRAN and everything works. What a great package!!!

Same error here and the following command:
devtools::load_all()
gives

Error: No root directory found in ... or its parent directories. Root criterion: contains a file DESCRIPTION

Same error here .. Not found a solution yet.

EDIT: see this post, it worked for me:

[Shiywa]

the same error about Could not find tools necessary to compile a package when i run devtools::install_github('cole-trapnell-lab/monocle3')

then, when I run devtools::load_all(), i got

No root directory found in /home/wangshiyou or its parent directories. Root criterion: contains a file `DESCRIPTION`

I used anaconda to manage my R , version 3.5.1 in linux. could you please give me some advice ?
