Installation of SciRuby failed on Mac OS X

I am trying to install SciRuby on Mac machine but the installation failed. I have searched this issue but didn't help much and the issued were related to a different error.
when I used the command

gem install sciruby
Successfully installed sciruby-0.2.11
Parsing documentation for sciruby-0.2.11
Done installing documentation for sciruby after 0 seconds
1 gem installed

It successfully installed it. But when I used the command

gem install sciruby-full

I get this error

Building native extensions. This could take a while...
ERROR:  Error installing sciruby-full:

I am using

ProductName: Mac OS X
ProductVersion: 10.15.1

ruby 2.6.3p62 (2019-04-16 revision 67580) [universal.x86_64-darwin19]

Apple clang version 11.0.0 (clang-1100.0.33.12)

I think the error is due to gcc or clang related things. A detail explanation and solution of the above issue is highly appreciated.
