Don't see "tree" package in my installation list

Hello,
Recently I updated my R and Rstudio and tried to install tree package, but don't see it.
I am looking for help. The error message is given below.

(as ‘lib’ is unspecified)
Warning in install.packages :
package ‘tree’ is not available (for R version 3.5.3)

I have tried on two computers via both R console using install.packages("tree") and Rstudio package install, neither of them found tree packages on neither of computers. Your help will be very much appreciated.
Thanks,
Lianfen

The tree package depends on R (≥ 3.6.0) and apparently you are using 3.5.3 version.
You would have to update R in order to install tree package.
