Rails3を試してみる

参考(ってか、そのまんま):#200 Rails 3 Beta and RVM - RailsCasts

とりあえずRVMで確認してみる

rvm:All about Ruby on Rails & Data recovery software

> rvm 1.9.1
> ruby -v
ruby 1.9.1p376 (2009-12-07 revision 26041) [i386-darwin10.2.0]

必要そうなgemをインストール

> sudo gem install tzinfo builder memcache-client rack rack-test rack-mount erubis mail text-format thor bundler i18n
Successfully installed tzinfo-0.3.16
Successfully installed builder-2.1.2

Successfully installed rack-mount-0.5.0
Successfully installed erubis-2.6.5
Successfully installed mail-2.1.2

Due to a rubygems bug, you must uninstall all older versions of bundler for 0.9 to work

rails3をインストールする

> sudo gem install rails --pre
ERROR: Error installing rails:
actionpack requires rack-mount (~> 0.4.0, runtime)

なんかrackのバージョンエラーが出た。
最新のrackは入っているのにー。

考えるのめんどいのでrackの0.4.0をインストール

> sudo gem install rack-mount --version=0.4.0
Successfully installed rack-mount-0.4.0
1 gem installed

インストールできた。

バージョン確認

> rails -v
/Users/******/.rvm/gems/ruby-1.9.1-p376/gems/rubygems-update-1.3.5/lib/rubygems.rb:384:in `bin_path': can't find executable rails for rails-3.0.0.beta (Gem::Exception)
from :345:in `method_missing'
from /opt/local/bin/rails:19:in `

'

同じウィンドウだとエラーが出るっぽいので、新規コマンドウィンドウを表示させる

> rails -v
Rails 3.0.0.beta

オッケー

サーバ起動

サーバ起動のコマンドが変わっている

> rails server
……
なんか警告っぽいものが出たり出なかったり
……
[2010-02-10 13:07:42] INFO WEBrick 1.3.1
[2010-02-10 13:07:42] INFO ruby 1.9.1 (2009-12-07) [i386-darwin10.2.0]
