There are binary versions available but the source versions are
later:
binary source needs_compilation
pkgload 1.0.2 1.1.0 TRUE
roxygen2 7.1.0 7.1.1 TRUE
devtools 2.2.2 2.3.1 FALSE

Do you want to install from sources the packages which need compilation? (Yes/no/cancel) yes

The first issue you need to tackle is this one, you are missing a package dependency, try installing it first.

install.packages("backports")

Do you get any error message while doing so?

That was the issue. I was able to install devtools and rstan after installing backports. Thank you so much for the help!!!
