Fast question.
I am setting up Jenkin CI for my Rails project. Almost every online installation guide ask for RVM to be installed along with Jenkin's RVM Plugin. While I use chruby for Ruby versioning instead of RVM, I only need Ruby 2.0 for my project.
Is RVM required to run a Rail app on Jenkins?
From what I have seen, no. It would be helpful, as with the RVM plugin for Jenkins, I believe you can manage the gemset that you use for that Jenkins project through Jenkins. But my suggestion is try it and if it doesn't work, go the RVM route. Without using RVM, I believe Jenkins will just use the default ruby without having the option to change from within Jenkins.

Am using Jenkins 2.303.1 - Community version. We have to deploy Ruby on rails application through Freestyle/Pipeline job hence we need to install RVM plugin but it is not visible/available for us to download.
May i know the reason/any other way to install RVM plugin. Please suggest
I've installed Ruby on a Windows computer
After Setting Up Ruby Installer What Command line tools do you use?
http://railsinstaller.org/en
I've tried the command
rvm use 1.9.3
using the command prompt ruby and rails
I get the error message
rvm is not a recognised command
From RVM’s FAQ:
Does RVM work on windows? Will it in the future?
NO. If you would like to manage multiple versions of ruby on windows please use pik which is an excellent tool by Gordon Thiesfeld. You can find it on GitHub. There are plans to include windows support in RVM 2.0.

Doing Rails development on Windows is a little bit more of a challenge and you may run into some annoyances, but it's definitely possible.
Uru worked well for me as a nice alternative to RVM, which doesn't run on Windows. However, if you just want to have one version of Ruby installed on your computer and work with it, you don't even need to bother with Uru.
Windows is not the best environment to develop with Ruby ...
RVM doesn't work and PIK hasn't updated for more than 2 years..

This installer doesn't install RVM. It installs Ruby interpreter and Rails.
Since you've installed it, I assume you have your Ruby and libraries for it (called gems) rails and bundler. Execute gem list in your shell to verify (it should output a looong list).
Then you should create a new Rails project:
rails new project_name
...and then go into the folder that got created
cd project_name
bundle what you have:
bundle install
...and launch the server to see if it works:
rails server
or
rails s
You will likely run into issues with tzinfo gem if you're on 64-bit Windows, but that can be easily fixed by searching around StackOverflow, it's been discussed.
Gool luck to you. Developing Rails applications in Windows proved to be hard to me. Consider launching a virtual machine (using, for example, VirtualBox) with Linux aboard. That's what you could do in Linux:
install RVM as the site suggests:
curl -sSL https://get.rvm.io | bash -s stable
install the latest MRI available - feel free to replace ruby with the version you need, like rvm install 2.0.0
rvm install ruby
select and set as default the Ruby you need, you've tried a similar line apparently with Ruby 1.9.3
rvm --default use ruby
another long process
gem install rails
rails new project_name
(same as described above)
cd project_name
bundle install
rails s
That should work, and that's what you've probably seen. Again, I highly recommend using Linux in VirtualBox (or anything similar) for Rails development. A native Linux installation could only be a better environment, but most people are not ready for this just yet.
I currently use rvm on my dev box (osx) but I use the system ruby on my server (1.8.7 on Ubuntu 10.04)
I want to upgrade the server to 1.9.3 and have been researching the best way to do it.
The server is running about four Rails applications all on version 3.2.11.
My options appear to be using rvm or alternatively using the 1.9.3 deb package and the ruby-switch gem provided by BrightBox (who also provide passenger packages)
The Brightbox packages appear to be a clean way to go but I thought I would ask a question here to see if there are any advantages or disadvantages of either approach that I have not thought about.
Rvm is useful when you need to have two or more versions of Ruby on the same machine. Development machines tend to have this. There is no need to use a version manager if your production box only requires one version of Ruby.
To this effect, I'd suggest you're correct in doing a single installation from the deb package. I can see the ruby-switch gem gives similar functionality to rvm - up to you as to whether that's important. But if you're using three apps on the same version of ruby, it may not be!
As I have started using Linux (Ubuntu) to broaden my knowledge, but the flow for ruby (rails) development does not feel so smooth as on Mac OSX.
Do you use rvm to manage ruby gems in Linux?
One particular issue I face is that I could install rails with only sudo command. But this forces me to use sudo for all the time under my rails project.
P.S.
Might be I am missing some point with the way you do things in Linux so it is not related to ruby (or rails) at all.
It is preferred to use rvm. we can install ruby and rails without rvm as well, but we can have only one version at a time. You can find the instructions to install rvm from following link - rvm installation.
If you are the only person working on ruby rails, install in single user mode(doesn't need to go with sudo)
Installing ruby and rails only using superuser privileges means you're installing it from distribution packages. That's not recommended, and you get unneeded overload writting sudo before any rails command.
Install rvm or rbenv in your home directory and things should be smooth.
I'm running Windows 7 32 bit. I just installed Ruby 1.9.2 and Rails 3.0.1. I set up my rails sample application and everything seems to be working fine. I tried installing the restful_authentication plugin from github and it's been a nightmare. I'm executing the following command:
rails plugin install -force git://github.com/technoweenie/restful-authentication.git
...and i get the get the following error:
Cannot install using checkout because this project is not under subversion.
How do i get around this? I've installed both the SVN and Git command-line clients and they're in my PATH.
Yep, you should not use this plugin with Rails 3. Use devise.
Get a linux or a mac for Rails development.
According to the installation notes you need to simply clone the project to the plugins dir.
git clone git://github.com/technoweenie/restful-authentication.git restful_authentication
As others have suggested, devise is a better option.
