試用了下Ruby on Rails

看《開源大本營》看到這一節，就動手試一下吧

 第一步，先到網上把要用到的安裝檔案Down下來，分別如下：
http://rubyforge.org/frs/download.php/12751/ruby185-21.exe
http://rubyforge.org/frs/download.php/16559/rails-1.2.1.gem
http://rubyforge.org/frs/download.php/16561/rails-1.2.1.zip
http://rubyforge.org/frs/download.php/16507/activesupport-1.4.0.gem
http://rubyforge.org/frs/download.php/16509/activesupport-1.4.0.zip
http://rubyforge.org/frs/download.php/16547/activerecord-1.15.1.gem
http://rubyforge.org/frs/download.php/16549/activerecord-1.15.1.zip
http://rubyforge.org/frs/download.php/16550/actionpack-1.13.1.gem
http://rubyforge.org/frs/download.php/16552/actionpack-1.13.1.zip
http://rubyforge.org/frs/download.php/16553/actionmailer-1.3.1.gem
http://rubyforge.org/frs/download.php/16555/actionmailer-1.3.1.zip
http://rubyforge.org/frs/download.php/16556/actionwebservice-1.2.1.gem
http://rubyforge.org/frs/download.php/16558/actionwebservice-1.2.1.zip

第二步，開始安裝
首先安裝Ruby1.85,然後進入CMD模式
C:/Downloads>gem install activesupport
C:/Downloads>gem install activerecord
C:/Downloads>gem install actionpack
C:/Downloads>gem install actionmailer
C:/Downloads>gem install actionwebservice
C:/Downloads>gem install rails
這樣就安裝好了

然後按照書上的例子，建資料庫，產生AddressBook應用程式，運行Rails
ruby script/server -d
沒運行起來，顯示如下：

c:/ruby/lib/ruby/1.8/yaml.rb:133:in `load': syntax error on line 18, col 2: `  h
ost: localhost' (ArgumentError)

Baidu了一下，發現是資料庫設定檔config/database.yml有問題

development:
  adapter: mysql
  database: AddressBook
  username: root
  password: micronsky.net
  host: localhost

:後面有一個空格
修改過來，再次運行，還是沒起來，顯示：

c:/ruby/lib/ruby/1.8/webrick/server.rb:29:in `fork': the fork() function is unim
plemented on this machine (NotImplementedError)

又搜了半天，沒找到原因，心想不會是-d參數的問題吧，於是去掉，運行，OK！

果然不錯，不過暫時是沒時間深入學習了，先擱這，有空了研究
