Updated bootstrap gem can't be loaded.

[angarc]

I don't think the bootstrap gem is communicating well with the bootsnap gem. As a result of this, the bootstrap gem can't be loaded. However, everything was working find before I updated to 4.3.1 (Before I was using bootstrap 4.1.3 but I updated because of the XSS vulnerability). Here's the error I get:

1: from /Users/username/.rvm/gems/ruby-2.5.1/gems/activesupport-5.2.3/lib/active_support/dependencies.rb:291:in `block in require'
