[Rails 4.1] Sprockets error shows undeclared dependency

[DanielKehoe]

When using Bootstrap with Rails 4.1.0, when visiting any page of the rails-bootstrap example app, I get this error:

Sprockets::Rails::Helper::DependencyError at /
Asset depends on 'bootstrap/glyphicons-halflings-regular.eot' to generate properly but has not declared the dependency
Please add: `//= depend_on_asset "bootstrap/glyphicons-halflings-regular.eot"` to '/Users/danielkehoe/workspace/wip/rails-devise-pundit/app/assets/stylesheets/framework_and_overrides.css.scss'

This is because sanity checks from the sprockets_better_errors gem have been merged into Rails 4.1. The intent is to reveal asset pipeline errors that you would see in production when you run the app in development mode. See rails/sprockets-rails#96

To resolve this, the rails_layout gem should update the framework_and_overrides.css.scss file to include:

//= depend_on_asset "bootstrap/glyphicons-halflings-regular.eot"
//= depend_on_asset "bootstrap/glyphicons-halflings-regular.svg"
//= depend_on_asset "bootstrap/glyphicons-halflings-regular.ttf"
//= depend_on_asset "bootstrap/glyphicons-halflings-regular.woff"

See RailsApps/rails-bootstrap#17

Looks like this was fixed in the bootstrap-sass gem:
twbs/bootstrap-sass@8bc2fca

See twbs/bootstrap-sass#578

Let's add a temporary fix to the rails_layout gem pending release of the next version of the bootstrap-sass gem. Otherwise I'll have to tell everyone to use the master version of the bootstrap-sass gem which means updating documentation everywhere, twice.

Thank you for this workaround. This is what happens when I jump too excitedly into a new version of Rails :)
Quick question, I'm having trouble locating the framework_and_overrides.css.scss file to update? This is definitely my lack of understanding. Any chance someone can point me in the right direction? Thanks!!

You're looking for app/assets/stylesheets/framework_and_overrides.css.scss.

The RailsApps tutorial has all the details:
http://railsapps.github.io/twitter-bootstrap-rails.html

You can use the new release of the rails_layout gem to fix things. Do a bundle update to get the new release. Then run

$ rails generate layout:install bootstrap3

Ah, that makes much more sense. Thank you so much!

Thanks for the work around!

@DanielKehoe Sorry, I believe this is a related question but... as of Rails 4.1, is the sprockets_better_errors gem no longer necessary based on your comment here?

[DanielKehoe]

@mecampbellsoup Yes, that's right.
