Quick install Ruby on Rails Concise guide _ruby topics

For new entry-level developers, how to install Ruby, Ruby Gems and Rails running environments can be a problem, and this page focuses on how to quickly install a ruby development environment with a plausible path.
The secondary installation method also applies to the product environment!
System Requirements

First determine the operating system environment, not recommended on Windows, so you need to use:

• Mac OS X
• Any Linux distributions (Ubuntu,centos, Redhat, ArchLinux ...)
• The strong novice uses Ubuntu to dispense with unnecessary trouble!

The following area of code, with a $ beginning representation needs to be executed below the console (terminal) (excluding the $ symbol)
Step 0-Install the package required by the system

# for MAC 
# First install [Xcode] (http://developer.apple.com/xcode/) development tool, it will help you install the Unix environment needs of the development Kit
# then install [Homebrew] (http:// brew.sh)
ruby-e "$ (curl-fssl https://raw.github.com/mxcl/homebrew/go/install)"

Step 1-Install RVM

What RVM is doing here is not explained, and you will be able to figure it out later.

$ curl-l Https://get.rvm.io | Bash-s Stable

The period may ask you the sudo administrator password, as well as automatically installs the dependency package through the homebrew, waits for a period of time can successfully install good RVM.

Then, load the RVM environment (the new open termal do not have to do so, will automatically reload)

$ source ~/.RVM/SCRIPTS/RVM

Check to see if the installation is correct

$ rvm-v
RVM 1.22.17 (Stable) by Wayne E. Seguin <wayneeseguin@gmail.com> Michal Papis <mpapis@gmail.com> [https://rvm.io/]

Step 2-Install Ruby environment with RVM

$ RVM Install 2.0.0

Also continue to wait for the long download, the compilation process, when finished, Ruby, Ruby Gems is installed.
Step 3-Set Ruby version

RVM installed, you need to perform the following command to set the specified version of Ruby to the system default version

$ RVM 2.0.0--default

Also, you can use a different version number, provided you have the RVM install installed that version.

This time you can test if it's right

$ ruby-v
Ruby 2.0.0p247 (2013-06-27 revision 41674) [x86_64-darwin13.0.0]

$ gem-v
2.1.6

$ gem source-r https://rubygems.org/
$ gem source-a https://ruby.taobao.org

Step 4-Install the Rails environment

After the 3 steps above, the Ruby environment is installed, and then Rails is installed

$ gem Install Rails

Then test that the installation is correct

$ rails-v
Rails 3.2.13

Then start your ruby,rails trip.
Welcome to Ruby's world!
