RVM で Ruby1.9.3 がうまく動いてくれないので、『rbenv』に乗り換えてみた

Rails を作った HDD のいる会社 37signals の人か作ったらしい『rbenv』をつかってみる
（環境: MacOSX10.7.4,）

Download: rbenv

$ cd
$ git clone git://github.com/sstephenson/rbenv.git .rbenv

Config: bash_profile or bashrc

export PATH="$HOME/.rbenv/bin:$PATH"
eval "$(rbenv init -)"

Download & install: ruby-build

$ git clone git://github.com/sstephenson/ruby-build.git
$ cd ruby-build
$ sudo install.sh

Install: ruby

修正: 2012-07-22
openssl と readline をインストールしてから
ruby をインストール。

openssl
- いれないとエラーになる
readline
- いれないとirbで日本語入力できない。

Macports でインストールした場合

$ cd
$ sudo port install openssl
$ sudo port install readline
$ CONFIGURE_OPTS="--with-openssl-dir=/opt/local --with-readline-dir=/opt/local" rbenv install 1.9.3-p194
$ sudo rbenv rehash

$ rbenv install 1.9.3-p194
Downloading http://pyyaml.org/download/libyaml/yaml-0.1.4.tar.gz...
$ sudo rbenv rehash

~~rbenv rehash 必要かも？~~ rbenv rehash 必要

Select: version

$ rbenv global
system
$ rbenv global 1.9.3-p194
$ rbenv global
1.9.3-p194
$ rbenv version
1.9.3-p194 (set by /Users/username/.rbenv/version)
$ rbenv versions
* 1.9.3-p194 (set by /Users/username/.rbenv/version)
ruby -v
