以编程方式获取完整的Ruby版本? [英] Programmatically getting FULL Ruby version?
本文介绍了以编程方式获取完整的Ruby版本?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我知道可以通过RUBY_VERSION常量获取Ruby版本(例如"1.9.3").但是，我想知道如何确定确切的版本(例如:"1.9.3-p0").原因是存在一个Ruby 1.9.3的早期版本中未修复的错误，该错误在更高版本中可用，并且我想在gem中使用一些代码来解决这个问题.
I know it's possible to get the Ruby version (e.g. "1.9.3") via the RUBY_VERSION constant. However, I want to know how to go about determining the exact version (e.g.: "1.9.3-p0"). The reason is that there is a bug that was not fixed in earlier versions of Ruby 1.9.3 that is working in later versions, and I want some code in a gem I'm working on to account for this.
推荐答案
也有一个RUBY_PATCHLEVEL常量.这样您就可以将版本字符串获取为
There is a RUBY_PATCHLEVEL constant as well. So you can get your version string as
"#{RUBY_VERSION}-p#{RUBY_PATCHLEVEL}"
