I'm getting an error when installing brms R package

I'm trying to install "brms" package but keep getting an error.
First, I installed "brms" package, and then call the package from the library.
I'm getting the following error message. "Error in library(brms) : there is no package called ‘brms’
Can someone help me?

install.packages("brms")

Note in the warning :
installation of package ‘brms’ had non-zero exit status means that the installation failed.

and there is no package called 'Brobdingnag' means that this dependency is missing
see ?install.packages
you can use the argument dependencies = TRUE

In that case, you probably didn't let the 'install' step finish. That package has a lot of dependencies. Try install.packages("brms") function again and wait for it to finish.
