ruby文件编译为exe文件

把ruby程序转变为windows下的exe可执行文件可以用以下gem

exerb
rubyscript2exe
ocra
我们重点介绍 ocra

https://github.com/larsch/ocra

安装方法(安装完ruby-windows，就自带gem了):

gem install ocra

ruby代码：

hw.rb

put “Hello world!”
打包:

ocra hw.rb

测试:

hw.exe

常用选项：

–windows    可以不显示控制台

–no-autodll  不包含依赖的dll库，可以把需要的dll放在执行目录下

–no-lzma     不压缩执行文件

–icon <ico>  指定icon图标
