Ok, I’m new to Rails, and I was hoping to get some advice on how to get started. I’m coming from a .NET background, and from what I’ve seen of Rails, it looks perfect for a little web idea I had. So I got a book from the library and sat down to install it on my Ubuntu box. Immediately I hit versioning issues. - I installed ruby with apt-get and it gave me 1.8.7. I’m cool with this as I’m new to Ruby as well, and am ignorant to the differences between versions. - Installed rubygems and I got 1.3.5. Again, I don’t know the difference - I ran ‘sudo gem install rails’, and it blew up on me, saying that I needed rubygems 1.3.6 or higher. When I do a gem list, it shows rails(3.0.0), which I hear just came out a week or two ago. Again, I don’t know the difference so that’s why I’m here. The book I got from the library is older(2007) and using Rails 1.2.3. So my question is: what’s the easiest way to get this setup? Is there a major difference between the versions of Rails, and if so, what is it? I just need a plain vanilla setup so I can learn about MVC and such. This web app is pretty basic, I was just wanting some basic ActiveRecord, a few Erb templates and a few dozen lines of ruby business logic. Can someone point me in the right direction? ---

Yes. Anything prior to 2.3.9 is old. Your choice right now is whether to go with 2.3.9 or 3.0.0. If you’re just starting out on a small project, I’d probably go with 3.0.0 as that’s where the future is going and enough has changed that you might as well start there. The only drawback is I don’t think any books are out yet for 3.0, but there should be plenty of online articles… > Can someone point me in the right direction?

Again, I don’t know the > difference I highly recommend RVM (Ruby EnVironment Manager). RVM is really simple to install and it makes installing Ruby and RubyGems drop-dead simple. You get to have as many different rubies and gemsets as you want.

Install RVM [http://rvm.beginrescueend.com/rvm/install/](http://rvm.beginrescueend.com/rvm/install/) 2. rvm install ruby-1.9.2 3. gem install rails 4. rails new my\_project 5. Add what you need to Gemfile in your Rails project (like sqlite3-ruby, etc.) 6. bundle install 7. Read up on all the other cool stuff RVM gives you. ---

Hi You can check out my blog post on this > **[Install Ruby on Rails on Ubuntu 10.04 Lucid Lynx](https://saurabhbhatia.tumblr.com/post/604423794/install-ruby-on-rails-on-ubuntu-1004-lucid-lynx)** > > Ubuntu 10.4 Lucid Lyx released a few days back and I took this opportunity to create a fresh installation on my system. The task that comes up with installation is installation and configuration of... For Installing a specific version of Rails do the following : sudo gem install -v=2.3.8 rails You can start learning it using [Ruby on Rails Guides](http://guides.rubyonrails.org/index.html) which covers Rails 2.3.8 Rails 3.0 is the current version of Rails. For getting started on it following are some links : [http://www.rubyinside.com/rails-3-0-beta-links-2966.html](http://www.rubyinside.com/rails-3-0-beta-links-2966.html) > **[蔡徐坤高清图片2020最\_蔡徐坤超帅的图片\_被窝网](http://www.railsnotes.com/rails-3/)** > > 美国(197)各房型的价格上涨蔡徐坤高清图片2020幅度为第二季度与第一季，蔡徐坤张艺兴合作蔡徐坤图片舞台（坤师傅是），为什么(204蔡徐坤超帅的图片)，乌克兰机场伤亡2020乌克兰顿涅 Regards ---
