Ruby2.0, Rails4.0 beta1のインストール

More than 5 years have passed since last update.

Ruby2.0のインストール

homebrewを使い、rbenv, ruby-buildでRubyをビルドする。

rbenv, ruby-build

homebrewは既にインストールされてる前提で。

$ brew install rbenv
$ brew install ruby-build

openssl, readline

OpenSSL, コンソールでの日本語利用のため、これらもインストールしておく。

$ brew install openssl
$ brew install readline
$ brew link openssl readline

こちらの記事
homebrew で入れた openssl を使って Ruby をコンパイルすると SSL 利用時に証明書エラーが発生する場合の対応
を参考に、curl-ca-bundleも。

$ brew install curl-ca-bundle
$ cp /usr/local/Cellar/curl-ca-bundle/1.87/share/ca-bundle.crt /usr/local/etc/openssl/cert.pem

Ruby

オプションつけて、rubyをインストール。

$ RUBY_CONFIGURE_OPTS="--with-readline-dir=`brew --prefix readline` --with-openssl-dir=`brew --prefix openssl`" rbenv install 2.0.0-p0

早速Ruby2.0をデフォルトに。

$ rbenv global 2.0.0-p0
$ ruby -v
ruby 2.0.0p0 (2013-02-24 revision 39474) [x86_64-darwin12.2.0]

bundlerも最後に入れとく。

$ gem install bundler
$ rbenv rehash
$ gem list bundler

*** LOCAL GEMS ***

bundler (1.3.0)

Rails4.0 beta1のインストール

やっとgemでインストールできるようになった。。

$ gem install rails -v 4.0.0.beta1
$ rbenv rehash
$ rails -v
Rails 4.0.0.beta1

Your bundle is complete! Use `bundle show [gemname]` to see where a bundled gem is installed.

生成されたGemfileは以下の様な感じだった。

Gemfile
source 'https://rubygems.org'                                                                       

# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.0.0.beta1'

gem 'sqlite3'

# Gems used only for assets and not required
# in production environments by default.
group :assets do
  gem 'sass-rails',   '~> 4.0.0.beta1'
  gem 'coffee-rails', '~> 4.0.0.beta1'

  # See https://github.com/sstephenson/execjs#readme for more supported runtimes
  # gem 'therubyracer', platforms: :ruby

  gem 'uglifier', '>= 1.0.3'
end

gem 'jquery-rails'

# Turbolinks makes following links in your web application faster. Read more: https://github.com/rails/turbolinks
gem 'turbolinks'

# Build JSON APIs with ease. Read more: https://github.com/rails/jbuilder

# Use unicorn as the app server

# Deploy with Capistrano

# To use debugger

以上。あとでrails g scaffoldとかしてみよう。
