Igraph installation does not work for R 4.0 on Windows?

I’m trying to install R package shinystan. I obtained some error message about installing igraph.

Then I tried to install igraph separately, Bu it seems not working for R 4.0. I’m using Windows 10.

Very much appreciate if you could advise how to solve it.

Error message:

compilation terminated.
make: *** [C:/PROGRA~1/R/R-TEST~1/etc/i386/Makeconf:217: feedback_arc_set.o] Error 1
ERROR: compilation failed for package 'igraph'

Warning in install.packages :

Probably the Windows binaries were not yet available at the time you tried to install igraph for R 4.0. They are available now however, I just tested it.
