Your Gemfile lists the gem bootstrap-sass (= 3.3.7) more than once.
You should probably keep only one of them.
While it's not a problem now, it could cause errors if you change the version of one of them later.
Warning: the running version of Bundler (1.15.2) is older than the version that created the lockfile (1.16.2). We suggest you upgrade to the latest version of Bundler by running `gem install bundler`.

Post-install message from sass:
Ruby Sass is deprecated and will be unmaintained as of 26 March 2019.
* If you use Sass as a command-line tool, we recommend using Dart Sass, the new
primary implementation: https://sass-lang.com/install
* If you use Sass as a plug-in for a Ruby web framework, we recommend using the
sassc gem: https://github.com/sass/sassc-ruby#readme
