I am using bootstrap gem in my project.

gem 'twitter-bootstrap-rails'

The bootstrap version that i have now is 

/*! normalize.css v3.0.1 | MIT License | git.io/normalize */

I need to upgrade to latest bootstrap version.

It seems like the bootstrap version is not updated in the gem (https://github.com/seyhunak/twitter-bootstrap-rails/blob/master/app/assets/stylesheets/twitter-bootstrap-static/bootstrap.css.erb).

How can i upgrade the version in my application?

    The latest version of Bootstrap is 4.0.0. It will break your layout if you don't manually adjust things because B4 is totally incompatible with B3. – WebDevBooster Jan 31 '18 at 12:33

There are several options:

  1. You can fork twitter-bootstrap-rails gem, update BS to version 4 and edit your Gemfile: 

    gem 'twitter-bootstrap-rails', git: 'link_to_your_fork'

  2. You can migrate to bootstrap-rubygem gem instead which uses BS4

  3. You can download latest version of BS from official site and manually put .js and .css files to ./vendor/assets/ directory. Look at these SO answers for reference: first and second

For options 2 and 3 make sure you dont use helper methods in your code which twitter-bootstrap-rails gem provides
