Question

Im using the following guide for getting started with rails for ubuntu 9.10.
http://guides.rails.info/getting_started.html

I have installed both ruby and gem.

---

gokul@gokul-laptop:~$ ruby -v
ruby 1.8.7 (2009-06-12 patchlevel 174) [i486-linux]
gokul@gokul-laptop:~$ gem -v
1.3.6
gokul@gokul-laptop:~$

---

For rails,

---

gokul@gokul-laptop:~$sudo gem install rails

---

doesnt seem to give any response.
so used the synaptic package manager for installing it. And it seems to have installed correctly.

---

gokul@gokul-laptop:~$ rails
Usage: /usr/bin/rails /path/to/your/app [options]

Options:
-r, –ruby=path Path to the Ruby binary of your choice (otherwise scripts use env, dispatchers current path).

                                 Default: /usr/bin/ruby1.8
-d, --database=name              Preconfigure for selected database (options: mysql/oracle/postgresql/sqlite2/sqlite3/frontbase/ibm_db).
                                 Default: sqlite3
-D, --with-dispatchers           Add CGI/FastCGI/mod_ruby dispatches code to generated application skeleton
                                 Default: false
    --freeze                     Freeze Rails in vendor/rails from the gems generating the skeleton
                                 Default: false
-m, --template=path              Use an application template that lives at path (can be a filesystem path or URL).
                                 Default: (none)

Rails Info:

-v, --version                    Show the Rails version number and quit.
-h, --help                       Show this help message and quit.

General Options:

-p, --pretend                    Run but do not make any changes.
-f, --force                      Overwrite files that already exist.
-s, --skip                       Skip files that already exist.
-q, --quiet                      Suppress normal output.
-t, --backtrace                  Debugging: show backtrace on errors.
-c, --svn                        Modify files with subversion. (Note: svn must be in path)
-g, --git                        Modify files with git. (Note: git must be in path)

Description:
The ‘rails’ command creates a new Rails application with a default
directory structure and configuration at the path you specify.

Example:
rails ~/Code/Ruby/weblog

This generates a skeletal Rails installation in ~/Code/Ruby/weblog.
See the README in the newly created application to get going.

hope some one can help me with this…

Answer 1

If you want to get started with a stable version of Rails on Ubuntu 9.10 I’d suggest:

Remove any gems installed via apt, aptitude or synaptic and check that rubygems is at least at Version 1.3.5.

 gem -v
 sudo gem install sqlite3-ruby rails # will install Rails 2.3.5 = latest stable release
 rails app
 cd app
 rake db:create
 script/server

---

If you want to learn Rails 3 (currently beta3)

Remove the RUBYGEMS package installed via apt, aptitude or synaptic and install RubyGems 1.3.6 manually.

wget http://production.cf.rubygems.org/rubygems/rubygems-1.3.6.tgz
tar xfz rubygems*tgz
cd rubygems-*
sudo ruby setup.rb && cd ..
gem -v
# if gem command fails
sudo ln -s /usr/bin/gem1.8 /usr/bin/gem

sudo gem install sqlite3-ruby bundler rails -pre
# will install Rails 3.0.0beta3
rails app
cd app
bundle install
rake db:create
rails server
