[Rubygems-developers] cannot specify multiple required_ruby_versions.

Hello everybody,

Since 1.9 is out, the use of required_ruby_version of
Gem::Specification seems a good alternative to "allow any version of
ruby from 1.8.4 but lower than 1.9.0"

so, anyone will think: ok, I can do this:

spec.required_ruby_version = ['>=1.8.4', '<1.9.0']

then do rake gem and bingo, it gets build!

then, install:

gem install gem: gem installed successfuly!


require 'rubygems'
require 'test_gem'
ArgumentError: Illformed requirement [">= 1.8.4, < 1.9.0"]

This also happens when I try to uninstall the gem.



The required_ruby_version wasn't like that.
