Hi,
Thanks for your message. This is the output:
WARNING: Rtools is required to build R packages but is not currently installed. Please download and install the appropriate version of Rtools before proceeding:
https://cran.rstudio.com/bin/windows/Rtools/
also installing the dependencies ‘rlang’, ‘ellipsis’, ‘lifecycle’, ‘vctrs’
There are binary versions available but the source versions are
later:
binary source needs_compilation
rlang 0.3.4 0.4.11 TRUE
ellipsis 0.1.0 0.3.2 TRUE
vctrs 0.1.0 0.3.8 TRUE
pillar 1.3.1 1.6.1 FALSE
Do you want to install from sources the packages which need compilation?
y/n:
I actually downloaded and installed the Rtools from here:
https://cran.rstudio.com/bin/windows/Rtools/
This is the check:
Sys.which("make")
make
"C:\rtools40\usr\bin\make.exe"
Installing "rlang" comes also with the same error and requiring the Rtools. "ellipsis" is running, "lifecycle" comes with the same error like "rlang" and "vctrs" the same.....
Do you see any other issue?
