The last release of chruby is 3 years ago. No one faced this error?

If it's yes, I will remove these code.

Rubygems doesn't seem dependent on chruby in any way except the version check itself (at least by grepping the source), so if you mean removing the chruby version check altogether, that sounds pragmatic.
