Ruby on railsのインストール

さて、今日はrubyの環境とRuby on railsを入れておこう。

ここを参考に。

ちょっと書いてある内容と差分があったのでメモ

1) rvm requirements

以下のように必要なパッケージを自動でインストールしてくれた

~$ rvm requirements
Checking requirements for ubuntu.
Installing requirements for ubuntu.
Updating system..........................................................................................................
Installing required packages: gawk, g++, libreadline6-dev, zlib1g-dev, libssl-dev, libyaml-dev, libsqlite3-dev, sqlite3, autoconf, libgdbm-dev, libncurses5-dev, automake, libtool, bison, libffi-dev..................................................................................................................................
Requirements installation successful.


2) rubyのインストール

rubyのサイトを見るとまだ安定版は1.9.3のようなので、1.9.3をインストール。

~$ rvm install 1.9.3

かなり時間がかかると書いてましたが、数分程度でした。

~$ ruby -v
ruby 1.9.3p448 (2013-06-27 revision 41675) [x86_64-linux]


3) gemsのインストール

~$ gem -v
2.1.10


4) railsのインストール

これはちょっと時間がかかる。

なんか、ASCII-8BIT から UTF-8 の変換ができんとかいってるけど、無視かな。

~$ rails -v
Rails 4.0.0

おっと、今だと4.0.0がインストールされるのか。

＜終了＞

と、ここまで２０分程度。すごく簡単に完了。依存関係とかで結構はまった経験があるのだが、rvmからの手順だとあったりなのね。それともubuntuだからなのか？

先々は、apache + passengaerで動かそうと思ってる。rvmだと個人の環境にインストールされるが、システムへのインストールとかもできるのかなとおもって調べたら、rootで入れれば/usr/local/rvmにインストールされるのね。便利ねぇ。
