Error in if (download_method_secure ()) from installing native R kernel for Jupyter

I tried installing R Kernel on my Jupyter laptop on Windows from

devtools::install_github('IRkernel/IRkernel')

but I ran into this error

Error in if (download_method_secure()) { :
missing value where TRUE/FALSE needed

Any suggestions on how to fix this would be appreciated.

This issue arose for me when I relied on the default devtools version r-essentialsinstead of the newest version. After I did conda install -f -c r r-devtoolsand received the latest version, the error disappeared. YMMV, of course.
