When I execute the command rails server, the following message appears to me::

Could not find Gem byebug (> = 0)

This is in Windows. I tried using a gem install byebug but it doesn’t work and Linux has the following message:

could not find Gem Rails

with the version of Ruby 1.9 and the Rails 2.4. Someone could help me please, I’m new to Ruby.
