零、Ubuntu的安裝
官網下載,我裝的是12.04的x64版。
一、系統升級
更換ubuntu的源
1.備份更新源
$ sudo cp /etc/apt/sources.list /etc/apt/sources.list.backup
2.修改更新源
$ sudo gedit /etc/apt/sources.list
使用以下網易源或搜狐源,直接替換檔案內容(教育網使用者請搜尋教育網神速專用源)

3.更新
$ sudo apt-get update
以上一步必須正常通過。
安裝curl:
$ sudo apt-get install curl
二、使用RVM安裝Ruby
RVM = Ruby Version Manager
輸入以下命令安裝RVM,並安裝最新stable版的ruby
$ \curl -L https://get.rvm.io | bash -s stable --ruby
安裝完成後,輸入以下命令檢查ruby安裝情況:
$ ruby -vruby 2.1.2p95 (2014-05-08 revision 45877) [x86_64-linux]
若已安裝RVM,則使用以下命令:
$ rvm get stable --autolibs=enable$ rvm install ruby$ rvm --default use ruby-2.1.2
三、安裝JavaScript Runtime
$ sudo apt-get install nodejs
四、更新Gem Manager
更新gem:
$ gem update --system$ gem -v2.4.1
更新gem源:
$ gem source -l$ gem source -r https://rubygems.org/$ gem source -a http://ruby.taobao.org/
五、更新RVM全域gemset
查看全域gemset中的gem:
$ rvm gemset use global
$ gem list
更新至最新的stable gem:
$ gem update
安裝nokogiri:(慢)
$ gem install nokogiri
六、安裝Rails
建立一個rails4.1的gemset
$ rvm use ruby-2.1.2@rails4.1 --create
安裝最新版本的rails
$ gem install rails$ rails -v
例如,你可以再建立一個rails3.2的gemset,安裝
$ rvm use ruby-2.1.2@rails3.2 --create$ gem install rails --version=3.2.19$ rails -v
在gemset間切換:
$ rvm use ruby-2.1.2@rails4.1$ rvm use ruby-2.1.2@rails3.2
七、rails的hello world
切換至工作目錄
$ rails new demo
$ rails s
用瀏覽器開啟http://localhost:3000/,顯示如片說明安裝成功
