I originally posted this to Rails Talk; someone there suggested I move it here.
The instructions here http://rubyonrails.org/download say:
1. Download + install Ruby. 2. Download + install gems. <- NB: Unnecessary for Ruby 1.9+ as it already includes RubyGems 3. gem install rails.
Step 2 errored on my Win7 machine after installing Ruby 1.9.2 in step 1. Turns out it wasn't necessary at all.
I'd like to propose a change in the wording of step 2. It currently says:
RubyGems is the standard Ruby package manager. It's similar to apt-get, emerge, and other OS package managers. Download (extract, then run "ruby setup.rb")
I think it should say:
RubyGems is the standard Ruby package manager. It's similar to apt-get, emerge, and other OS package managers. RubyGems is included in Ruby 1.9 and higher. For other versions: Download (extract, then run "ruby setup.rb")
