Ruby on Rails GemNotFound / FetchError / connection attempt failed!

I didn't post for a very long time!
I had alot of sketches though but didn't had the time to finish and publish them..

But i hope to come back now with more posts!
Also i'm gonna stick to a new format in my posts thati think is better to read. maybe i'll also update old posts to this format.

I just started learning Ruby on Rails few weeks ago and ran into a very weird problem.


I'm using Windows 7 64bit with RubyMine 4.5.1, Ruby 1.9.3, Rails 3.2.

I was able to install all this working environment on my Desktop but not on my Laptop..


I encounterd the following errors on cmd & RubyMine:
C:\Users\Danpe>gem install rails
WARNING:  Error fetching data: Errno::ECONNREFUSED: No connection could be made
because the target machine actively refused it. - connect(2) (http://rubygems.org/latest_specs.4.8.gz) 
`block in materialize': Could not find rake- in any of the sources (Bundler::GemNotFound)

Fetching source index for `http://rubygems.org/`  Could not reach rubygems repository `http://rubygems.org/`  Could not find gem 'rspec-rails (>= 2.0.0.beta.22, runtime)' in any of the gem sources.

 ERROR: http://rubygems.org/ does not appear to be a repository       ERROR:  While executing gem ... (Gem::RemoteFetcher::FetchError)
 Errno::ETIMEDOUT: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed
because connected host has failed to respond. - connect(2)           (http://rubygems.org/yaml)
 I got all these kind of weird errors!


 so i started looking around the web and around my PC network settings.

I double checked my Internet Options to see that there is no proxy enabled, and there was none!
I opened cmd and typed SET to see my Environment Variables:

 As you can see there is an Environment Variable for HTTP_PROXY...


Go to Start (WinKey) type Edit the system environment variables and you'll get this window:

Click on Environment Variables and then remove HTTP_PROXY from System Variables!

Make sure you reopen cmd and RubyMine :)
