How to know bootstrap version in rails

Question

I'm using bootstrap-sass (3.3.1.0) in my Rails project.

How can I know the twitter bootstrap itself's version?

I found this question, but there were no answer for Rails environment.

How to identify bootstrap version? - Stack Overflow

following @Avdept's answer

$ bundle exec gem which bootstrap-sass
/Users/ironsand/.rbenv/versions/2.1.3/lib/ruby/gems/2.1.0/gems/bootstrap-sass-3.3.1.0/lib/bootstrap-sass.rb
$ cd /Users/ironsand/.rbenv/versions/2.1.3/lib/ruby/gems/2.1.0/gems/bootstrap-sass-3.3.1.0/
$ find . -name "*.css"
$ find . -name "_bootstrap.scss"
./assets/stylesheets/_bootstrap.scss

So I couldn't find bootstrap.css in which there is version number.

In most cases inside gems are same css as in original version. You can find path of where your gem installed using

gem which bootstrap-sass

Then just go to this folder, find css file and check top of css file
