/usr/lib/ruby/2.2.0/rubygems.rb:8:in require’: cannot load such file –
rbconfig (LoadError)
from /usr/lib/ruby/2.2.0/rubygems.rb:8:in< top (required) >’

I am completely new to it. Somebody please help me.

I am using win 7

I have done many Windows 7 Ruby installations. I am guessing that you
are
working from old documentation. Where were you informed to run ruby
setup.rb?

3

I am following Ruby on Rails 3 Tutorial LiveLessons Bundle by Michael
Hartl’s instructions.

So
I installed Cygwin64 Terminal
Downloaded rubygems-2.4.8 from official website
Cd to rubygems-2.4.8
ls
—There i found setup.rb

$ ruby setup.rb
/usr/lib/ruby/2.2.0/rubygems.rb:8:in require’: cannot load such file –
rbconfig (LoadError)
from /usr/lib/ruby/2.2.0/rubygems.rb:8:in< top (required) >’
from < internal:gem_prelude >:1:in require’
from internal:gem_prelude:1:in< compiled > ’

This is it. Please help me out.

Thanks for the reply.

I tried echo $RUBYOPT…it returned empty

Then i followed instructions in
https://rubygems.org/pages/download#formats

Download from above
Unpack into a directory and cd there
Install with: ruby setup.rb (you may need admin/root privilege)

But the same error persist. A friend of mine suggested rails installer.
So i am gonna install that. Anyways thanks for your time.

You can also try railsintaller ( Install Ruby on Rails – Railsinstaller.org - ). Back
then
when I had windows, I used that as far as I can remember.

I’m no authority on ROR on cygwin66… Not making any promises…

Did a little research, and found this at:
http://code.openhub.net/file?fid=_l-OijNPFX7fzeTZ7tG1bdwGj-U&cid=teq11amO2NQ&s=&fp=299059&mp&projSelected=true#L0

It’s setup.rb, obviously you can search your environment for setup.rb to
trace the rbconfig error…

Seems that if rubygems are already loaded you will get a rbconfig error.

if RUBY_VERSION < “1.8.7”
$stderr.puts “Rubygems now requires Ruby 1.8.7 or later”
exit 1
end

Make sure rubygems isn’t already loaded.

if ENV[‘RUBYOPT’] or defined? Gem then
ENV.delete ‘RUBYOPT’

require ‘rbconfig’
config = defined?(RbConfig) ? RbConfig : Config

ruby = File.join config::CONFIG[‘bindir’],
config::CONFIG[‘ruby_install_name’]
ruby << config::CONFIG[‘EXEEXT’]

cmd = [ruby, ‘setup.rb’, *ARGV].compact
cmd[1,0] = “–disable-gems” if RUBY_VERSION > “1.9”

exec(*cmd)
end

Dir.chdir File.dirname(FILE)

$:.unshift ‘lib’
require ‘rubygems’
require ‘rubygems/gem_runner’
require ‘rubygems/exceptions’

Gem::CommandManager.instance.register_command :setup

args = ARGV.clone
if ENV[“GEM_PREV_VER”]
args = [ ‘–previous-version’, ENV[“GEM_PREV_VER”] ] + args
end
args.unshift ‘setup’

begin
Gem::GemRunner.new.run args
rescue Gem::SystemExitException => e
exit e.exit_code
end

So first I would try
echo $RUBYOPT
I believe that it should return empty, which may indicate that gems are
already installed

Then I would try…

skip ruby setup, and try

Following the instructions from
https://rubygems.org/pages/download#formats

gem update --system

Hope this help…
