1:Update package repository.
1 sudo apt-get update
2:Install git and Curl.
Git:是一个简单，快速，高效的版本控制系统。（对于安装ruby on rails 环境没有关系，只是为了在以后的开发过程中进行版本控制的时候使用。）
Curl:是一个根据web协议获取文件的简单命令行工具。
1 sudo apt-get install git 2 sudo apt-get install curl
3:Install RVM and Dependencies.
1 curl -L get.rvm.io | bash -s stable
load the RVM：
1 source ~/.rvm/scripts/rvm
Then install additional dependencies specified by the RVM
1 sudo apt-get -y install build-essential openssl libreadline6 libreadline6-dev zlib1g zlib1g-dev libssl-dev libyaml-dev libsqlite3-0 libsqlite3-dev sqlite3 libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev automake libtool bison subversion
4:Installing Javascript Runtime 参考：https://github.com/joyent/node/wiki/Installing-Node.js-via-package-manager
1 sudo apt-add-repository ppa:chris-lea/node.js 2 sudo apt-get update 3 sudo apt-get install nodejs
5:Install Ruby
1 rvm install 2.0.0
Then select the Ruby version you want to use
1 rvm use 2.0.0 --default
在此处出现如下问题：
steven@ubuntu:/usr$ rvm use 2.0.0 --default RVM is not a function, selecting rubies with 'rvm use ...' will not work. You need to change your terminal emulator preferences to allow login shell. Sometimes it is required to use `/bin/bash --login` as the command. Please visit https://rvm.io/integration/gnome-terminal/ for a example.
然后执行如下命令：
1 /bin/bash --login
解决此问题。
You can check the version of ruby
1 ruby -v
输出结果
ruby 2.0.0p247 (2013-06-27 revision 41674) [i686-linux]
6：Install Rails
1 gem install rails
7：test
1 steven@ubuntu:/usr/RubyProject$ rails new demo 2 create 3 create README.rdoc 4 create Rakefile 5 create config.ru 6 create .gitignore
