3.安装SQLite3
http://www.sqlite.org/sqlite-dll-win32-x86-3070400.zip
http://www.sqlite.org/sqlite-shell-win32-x86-3070400.zip
解压copy到:d:\Ruby192\bin目录.
sqlite3 -version


4.Create An Example Rails App
1>.From a command prompt, navigate to a directory where you want the application code to live
cd E:\BASICAPP\ror\apps
2>.Start by creating an empty Rails application called todos:
rails new todos
3>.Change into the todos directory that was created in the previous step:
cd todos
4>.The application doesn't know about todos yet, so we'll use scaffolding to quickly generate all the code for managing a list of todos. Run the scaffold generator by typing
rails g scaffold todo name:string due_on:date completed:boolean
You'll see Rails create a bunch of files, including a migration file for creating a database schema to store todo items in a database (SQLite3 in this case).
5>.Run the database migration by typing
rake db:migrate
6>.Then start the Rails app by typing
rails s
7>.Finally, point your web browser at http://localhost:3000 and you should see a page welcoming you to Rails. To start managing your todos, go to http://localhost:3000/todos.
8>.When you're done, you can stop the Rails app by typing CTRL-C in the command prompt where you started the app.

5.install the DevKit:
http://github.com/oneclick/rubyinstaller/wiki/Development-Kit
1>.Remove artifacts extracted by any of the legacy DevKit’s.
2>.Download the self-extracting DevKit-tdm-32-4.5.1-20101214-1400-sfx.exe archive.
3>.Extract the DevKit contents into a directory with no spaces, e.g. – d:\DevKit.
4>.Run the DevKit’s dk.rb init and install helper scripts to generate config.yml and enhance your installed Rubies.
ruby dk.rb init
ruby dk.rb install
5>.update your PATH
D:\DevKit\bin
6>.Run the gem install rdiscount --platform=ruby smoke test.
gem install rdiscount --platform=ruby

 

6.问题
1>.can't find executable rake for rake-0.8.7
到ruby1.9.2安装目录 /lib/ruby/gems/1.9.1/specifications/下，找到rake.gemspec这个文件，并删除掉，就恢复正常了
2>.
entry point rb_str2cstr could not be located in msvcrt-ruby191.dll
