Ruby on Rails チュートリアル を行うにあたって仮想マシン内では無くMac上に環境を構築することにしました。
0. 前提
- Mac OS X 10.11
- Homebrew
手元の環境には昔この辺の手順でインストールされた名残があったのでそのクリーンアップをしておきます。
$ rm -rf ~/.rbenv
1. rbenv, ruby-buildのインストール
$ brew update $ brew install rbenv ruby-build ==> Installing dependencies for rbenv: autoconf, ruby-build ==> Installing rbenv dependency: autoconf ==> Downloading https://homebrew.bintray.com/bottles/autoconf-2.69.el_capitan.bo Already downloaded: /Users/*****/Library/Caches/Homebrew/autoconf-2.69.el_capitan.bottle.4.tar.gz ==> Pouring autoconf-2.69.el_capitan.bottle.4.tar.gz ==> Caveats Emacs Lisp files have been installed to: /usr/local/share/emacs/site-lisp/autoconf ==> Summary 🍺 /usr/local/Cellar/autoconf/2.69: 70 files, 3.0M ==> Installing rbenv dependency: ruby-build ==> Downloading https://github.com/rbenv/ruby-build/archive/v20160602.tar.gz ==> Downloading from https://codeload.github.com/rbenv/ruby-build/tar.gz/v201606 ######################################################################## 100.0% ==> ./install.sh 🍺 /usr/local/Cellar/ruby-build/20160602: 282 files, 155.5K, built in 6 seconds ==> Installing rbenv ==> Downloading https://homebrew.bintray.com/bottles/rbenv-1.0.0.el_capitan.bott ######################################################################## 100.0% ==> Pouring rbenv-1.0.0.el_capitan.bottle.tar.gz ==> Caveats Rbenv stores data under ~/.rbenv by default. If you absolutely need to store everything under Homebrew's prefix, include this in your profile: export RBENV_ROOT=/usr/local/var/rbenv To enable shims and autocompletion, run this and follow the instructions: rbenv init ==> Summary 🍺 /usr/local/Cellar/rbenv/1.0.0: 36 files, 62.0K $ rbenv init
.bashrcに rbenv init を追記します。
$ echo 'eval "$(rbenv init -)"' >> ~/.bashrc $ source ~/.bashrc
2. rubyのインストール
現時点で一番最新の 2.3.1 をインストールします。
rbenv install --list で利用できるバージョンの一覧が出力されます。
$ rbenv install 2.3.1 rbenv versions * system (set by /Users/*****/.rbenv/version) 2.3.1 $ rbenv local 2.3.1 $ ruby --version ruby 2.3.1p112 (2016-04-26 revision 54768) [x86_64-darwin15]
3. bundlerを使ってrailsのインストール
チュートリアルだと ~/.rbenv の下にgemをインストールすることになるのでbundlerを使ってカレントディレクトリにrailsをインストールします。
$ gem install bundler Fetching: bundler-1.13.2.gem (100%) Successfully installed bundler-1.13.2 1 gem installed $ cat << _EOT_ > Gemfile source 'https://rubygems.org' gem 'rails', '4.2.2' _EOT_ $ bundle install --path vendor/bundle Fetching gem metadata from https://rubygems.org/..........

Bundled gems are installed into ./vendor/bundle. $ bundle exec rails -v Rails 4.2.2
後は rails コマンドを適宜 bundle exec rails に読み替えていけば良さそうです。
