From: Stu Date: 2011-04-29T13:52:13+09:00 Subject: Re: Ruby Beginner Need Help.. To install rails you will need sqlite3 installed( though you can use any db supported it's just default) Here is a console walk through to get you started. First a summer of commands used: -> % history 1 gem install rails 2 rehash 3 rails new my_web_app 4 cd my_web_app 5 bundle install 6 rails server (1) I install the rails gem. (2) I rehash for zsh. (3) I create my new application template with the rails new generator. (4) I change to my new application's directory. (5) run the bundler command to find any gems that may be not installed (i.e. sqlite3). (6) start the server. from there you can open your browser and see the welcome screen at http://0.0.0.0:3000 or localhost:3000 Further instructions can be found at the Rails guide link on that page. Here is a more verbose output from my console: -> % gem install rails Fetching: activesupport-3.0.7.gem (100%) Fetching: builder-2.1.2.gem (100%) WARNING: builder-2.1.2 has an invalid nil value for @cert_chain Fetching: i18n-0.5.0.gem (100%) Fetching: activemodel-3.0.7.gem (100%) Fetching: rack-test-0.5.7.gem (100%) Fetching: rack-mount-0.6.14.gem (100%) Fetching: tzinfo-0.3.27.gem (100%) Fetching: abstract-1.0.0.gem (100%) WARNING: abstract-1.0.0 has an invalid nil value for @cert_chain Fetching: erubis-2.6.6.gem (100%) Fetching: actionpack-3.0.7.gem (100%) Fetching: arel-2.0.9.gem (100%) Fetching: activerecord-3.0.7.gem (100%) Fetching: activeresource-3.0.7.gem (100%) Fetching: mime-types-1.16.gem (100%) Fetching: polyglot-0.3.1.gem (100%) Fetching: treetop-1.4.9.gem (100%) Fetching: mail-2.2.19.gem (100%) Fetching: actionmailer-3.0.7.gem (100%) Fetching: thor-0.14.6.gem (100%) Fetching: railties-3.0.7.gem (100%) Fetching: bundler-1.0.12.gem (100%) Fetching: rails-3.0.7.gem (100%) Successfully installed activesupport-3.0.7 Successfully installed builder-2.1.2 Successfully installed i18n-0.5.0 Successfully installed activemodel-3.0.7 Successfully installed rack-test-0.5.7 Successfully installed rack-mount-0.6.14 Successfully installed tzinfo-0.3.27 Successfully installed abstract-1.0.0 Successfully installed erubis-2.6.6 Successfully installed actionpack-3.0.7 Successfully installed arel-2.0.9 Successfully installed activerecord-3.0.7 Successfully installed activeresource-3.0.7 Successfully installed mime-types-1.16 Successfully installed polyglot-0.3.1 Successfully installed treetop-1.4.9 Successfully installed mail-2.2.19 Successfully installed actionmailer-3.0.7 Successfully installed thor-0.14.6 Successfully installed railties-3.0.7 Successfully installed bundler-1.0.12 Successfully installed rails-3.0.7 22 gems installed Installing ri documentation for activesupport-3.0.7...
