rtrools40 download error

[wilcar]

I have installed rstools40 "C:\rtools40\usr\bin\make.exe"

Can't download emo

devtools :: install_github ( " hadley / emo " ) Erreur : Failed to install 'unknown package' from GitHub: JSON: EXPECTED value GOT <

[cderv]

I don't think rtools is required for this package.

On R > 4.0 and windows 10, this works as expected

 devtools::install_github("hadley/emo")
# or
 remotes::install_github("hadley/emo")
