Error Installing rscopus

[joseprieto]

After installing devtool and Rtools's packages, when I code:
devtools::install_github("muschellij2/rscopus")
It retrieves the following:
Error: Failed to install 'rscopus' from GitHub: (converted from warning) cannot remove prior installation of package ‘curl’

The first part of the installation request you wheter update some packages or not. In this example, I don't make any update- It seems that curl is installed by default.

This is not an rscopus issue, but rather something from remotes.

Try

withr::with_envvar(c(R_REMOTES_NO_ERRORS_FROM_WARNINGS="true"), 
  remotes::install_github('muschellij2/rscopus')
)

or

Sys.setenv(R_REMOTES_STANDALONE="true")
remotes::install_github('muschellij2/rscopus')
