在freebsd 上裝rails實在很簡單。



# cd /usr/ports/www/rubygem-rails 
# make install clean 

// 裝完看一下裝了什麼
# ruby -v
ruby 1.8.7 (2009-04-08 patchlevel 160) [amd64-freebsd7]
# rails -v
Rails 2.3.3
# gem -v
1.3.4
# gem list
*** LOCAL GEMS ***
actionmailer (2.3.3)
actionpack (2.3.3)
activerecord (2.3.3)
activeresource (2.3.3)
activesupport (2.3.3)
hoe (2.3.2)
memcache-client (1.7.4)
rack (1.0.0)
rails (2.3.3)
rake (0.8.7)
rubyforge (1.0.3)
sources (0.0.2)
ZenTest (4.1.3)



但是我遇到下面的問題：


// 跑一支 testapp
# rails testapp
undefined method `camelize' for "app":String


我在這篇找到問題出在ruby-iconv：


// 裝ruby-iconv
# cd /usr/ports/converters/ruby-iconv
# sudo make install clean


有同樣問題可以試試

Install Ruby 1.9 & Rails 2.3 on Ubuntu

看Ruby on Rails 2.3 Release Notes列了一堆，不升上去玩玩怎行。但因為用 apt-get 只到 2.1，想要 2.3 只能手動安裝，裝之前我先把舊的都移乾靜，雖然沒移掉也沒差。
