Installing Ruby 1.8.7-p374 and Rails 3.2.13 error in rack-cache

Question

How can I installing Rails 3.2.13 in a Ruby 1.8.7?

My hosting server using these versions and I would like to set up a environment in Vagrant using a CentOS 7 box.

I install a Ruby 1.8.7 using a RVM.

When I trying to install the Rails 3.2.13, I received an error message: (rack-cache need ruby >= 2.0.0)

Any idea how can I install Rails 3.2.13 using Ruby 1.8.7 ?

[vagrant@ror02 ~]$ ruby -v
ruby 1.8.7 (2013-06-27 patchlevel 374) [x86_64-linux]

If you have rvm you may just install the latest ruby and rails. There is no need to use the system wide installed version.

I just use ruby 2.5.1 and rails 5.2.0.
