How to install Rails4

Previously on this blog, I installed Ruby 2.2.
The Ruby is running on the rbenv.

Upgrade Ruby from version 2.0 to 2.2 on Mac - Another Japan in the World

And that is because I will install Rails4.

This time, I will install Rails4.

Default ruby version is 2.0.

$ cd

$ ruby -v
ruby 2.0.0p481 (2014-05-08 revision 45883) [x86_64-darwin13.2.0]

Move to the directory to install rails4.
And set the ruby which is used under the this directory.

$ cd ~/git/test-rails4/

$ rbenv local 2.2.3

$ cat .ruby-version
2.2.3

$ rbenv version
2.2.3 (set by RBENV_VERSION environment variable)

$ ruby -v
ruby 2.2.3p173 (2015-08-18 revision 51636) [x86_64-darwin13]

Install Bundler.
Bundler is like a Carton in Perl, and a Composer in PHP.

$ rbenv exec gem list

*** LOCAL GEMS ***

bigdecimal (1.2.6)
io-console (0.4.3)
json (1.8.1)
minitest (5.4.3)
power_assert (0.2.2)
psych (2.0.8)
rake (10.4.2)
rdoc (4.2.0)
test-unit (3.0.8)

$ rbenv exec gem install bundler

$ rbenv exec gem list

*** LOCAL GEMS ***

Create Gemfile.

$ rbenv exec bundle init
Writing new Gemfile to $HOME/git/test-rails4/Gemfile

Edit Gemfile to install Rails 4.2.4.

$ vi Gemfile
source "https://rubygems.org"

gem "rails", "4.2.4"

Install gem modules under the vendor/bundle.

$ rbenv exec bundle install --path vendor/bundle

$ ls vendor/bundle/ruby/2.2.0/ | cat
bin/
build_info/
cache/
doc/
extensions/
gems/
specifications/

Check gem modules which are installed by Bundler.

$ rbenv exec bundle list
  * actionmailer (4.2.4)
...
  * rails (4.2.4)
...
  * tzinfo (1.2.2)

Create rails project "project-foo" with SQLite. SQLLite is default DB.

$ rbenv exec bundle exec rails new project-foo --skip-bundle
      create
      create  README.rdoc
...
      create  vendor/assets/stylesheets
      create  vendor/assets/stylesheets/.keep

$ ls project-foo/ | cat
.gitignore
Gemfile
README.rdoc
Rakefile
app/
bin/
config/
config.ru
db/
lib/
log/
public/
test/
tmp/
vendor/

Move to Rails project directory. and Install gem modules which are defined in Gemfile.

$ cd project-foo/
$ rbenv exec bundle install --path vendor/bundle

Finally, run Rails server in development.

$ rbenv exec bundle exec rails server

=> Booting WEBrick
=> Rails 4.2.4 application starting in development on http://localhost:3000
=> Run `rails server -h` for more startup options
=> Ctrl-C to shutdown server
[2015-09-08 02:12:09] INFO  WEBrick 1.3.1
[2015-09-08 02:12:09] INFO  ruby 2.2.3 (2015-08-18) [x86_64-darwin13]
[2015-09-08 02:12:09] INFO  WEBrick::HTTPServer#start: pid=51090 port=3000

Then access to http://localhost:3000, and check the page.
