undefined method `environment' for nil:NilClass when importing Bootstrap

Question

I\'ve been trying to import Bootstrap into my rails app and I\'m not quite sure what\'s going wrong. I\'ve had it working before, but I did a \'bundle update\' and destroyed

Answer 1

It was a gem version conflict.

Please use

gem 'sass-rails', '~> 4.0.0'

instead of

gem 'sass-rails'

Perform bundle update right after that. That should fix it
