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。

举例如下:
irb(main):010:0> "show trsult: #{1*3}"
=> "show trsult: 3"
irb(main):011:0> 'show trsult: #{1*3}'
=> "show trs ......

Installing Ruby from source is my preferred method, although in Ubuntu Feisty you can supposedly install it with apt-get install ruby
now. Here’s the essential packages needed to get a source build working right though and the process I just went through:
sudo apt-get install build-essentia ......
