Trying to install Rails and create new project, but not possible

I know there are many similar questions but I couldn't find any suitable answer for mine from previous questions, please don't flag this questions as already existing. I would be very grateful if someone help me get going with my rails project on my laptop.

First of all I want to say few things which I have tried. I have been able to successfully install Rails on my personal pc using Rails installer and I have started and done few sample app/ projects.

BUT THE PROBLEM IS WHEN I AM TRYING TO INSTALL RAILS ON MY WORK(COMPANY) LAPTOP(Windows Vista) and start a new rails project I think the proxy is blocking gem install but I dont know how to overcome it.

I tried many ways

1. Rails installer
2. installing radrails and then installing rails on it
3. installing ruby and then doing gems install rails

I have been unsuccessful all these ways, I have been trying for 2 days, so any help is greatly appreciated.

I am trying to install ruby 1.9.2, rails 3.1.0 when I do ruby -v & also ra开发者_如何转开发ils -v I get the above results, but when I say

>rails new project

but the project is created , when I cd to the project

I didn't face any of these problems when i s=installed Ruby and Rails on my personal notebook.

I have a similar setup for Rails (perviously Windows XP, now Windows 7, Rails 3.x, intranet of my company) and the following setup works for me:

• Set the environment variable (Settings > System > Environment Variables or similar, I have a German Windows here) HTTP_PROXY to a working proxy (depending on your company) like http://proxy.my-company.com:80.
• It has to include the protocol and the port.
• Try then in a new opened shell echo %HTTP_PROXY%. You should see your definition.
• Then e.g. gem list rails -r.

This should list all (remote) gems available. Bundles does use that as well.
