install_github - "Error: 'setInternet2' is Defunct"

[jesse-smith]

When attempting to install packages using 'remotes::install_github', this error appears:

> remotes::install_github("r-lib/devtools")
Error: 'setInternet2' is defunct.
See help("Defunct")

R version 3.5.1 (2018-07-02)

The error is reproducible when attempting to install several different packages. Not sure if this helps, but as of r version 3.3.0, only use = NA is accepted as input to setInternet2 (see here).

Update: the error occurs when using 'install_local' as well.

I am seeing this error also.

setInternet2 should definitely be removed from internal method download_method_secure. There are suprisingly 2 functions in install_github.R and download.R.
This test with setInternet2 is not needed anymore as internal default to wininet method on windows and support https.

Also, Is this with the dev version of remotes ? Or CRAN 3.5.1 ?
I don't if it is related but there where changes recently and, as a workaround, you may need to set options(download.file.method = "wininet") as remotes now defaults to libcurl in some case.

I'll do this one
