Ruby打包发布

http://www.erikveen.dds.nl/distributingrubyapplications/rails.html:
In this tutorial, we'll go through the following steps: Setup the environment Create the SQLite database Develop the Rails application Create the RBA (= Ruby archive) from the application with Tar2RubyScript Create the standalone executable with RubyScript2Exe module Rails
  class Configuration
    def database_configuration
      #conf = YAML::load(ERB.new(IO.read(database_configuration_file)).result) 会出错
      conf = YAML::load(File.read(database_configuration_file))
      if defined?(TAR2RUBYSCRIPT)
        conf.each do |k, v|
          if v["adapter"] =~ /^sqlite/
            v["database"] = oldlocation(v["database"]) if v.include?("database")
            v["dbfile"]   = oldlocation(v["dbfile"])   if v.include?("dbfile")
          end
        end
      end
      conf
    end
  end
end   "database"=>"E:/worksapce/temp/db/demo_development.sqlite3", oldlocation(v["database"]) 其实是在DB子目录中,而不是在当前运行的目录下

tar2rubyscript可以了
rubyscript2exe 不行,有可能是RAILS版本问题, 现在证明不是RAILS版本问题,估计是RUBY 版本问题 2.Exerb不能通过gem安装,不过安装方式也十分方便。
       首先到exerb的官方网站下载exerb.链接在页面中间那个位置。
