I can confirm that this is happening on an existing, large Rails application I work on (Ruby 2.4.4 / Rails 5.1.5). It is not happening on a brand new Rails application with roughly the same versions (Ruby 2.4.4 / Rails 5.1.6), nor on current versions (Ruby 2.5.0 / Rails 5.2). Below are the contents of the Rails error page:

Our application is reasonably big, and is using Ruby 2.5.3p105, and Rails 5.2.1 (progressively migrated from Rails 3.2). The error is happening in the same place: the stylesheet_link_tag in the html. Could it be some kind of setting from an earlier Rails version that gets migrated, and should be removed in order for sassc to work ? |

Hi Ryan, That's it ! I also had an assets group in the Gemfile due to coming from an older version of Rails. I moved the sassc-rails gem back to its previous location and removed the assets group, and everything is still working :-). Thorsten, I opened and closed the issue again. Please tell me if you think there is a need to re-open it. |

Strangely this still is a problem for me in a new rails 6.0.0 app and moving I also don't seem to have an assets block in my Gemfile. This is what the Gemfile looks like: This is the exception stacktrace: |

One oddity worth mentioning is that the `rails app:webpacker:compile` won't execute unless the `bin/webpack` file exists. The file doesn't need any contents, but there must be a presence check guard clause. The corresponding `test/dummy/bin/webpack` _does_ exist, and properly configures and executes the [Webpack CLI commands][webpack-cli].

I'm working on Rails 6.1 app where I actually want to remove the old sass-rails gem and, ideally, NOT replace it with the new gem because our app does not use sass whatsoever.

Hi,
I am trying to move from sass-rails to sassc-rails due to sass-rails becoming obsolete and due to big compilation delays (having rack-time-outs when reloading after changing a sass file),.
When I start my development server after replacing sass-rails with sassc-rails I get the following error:
cannot load such file -- sass (in the line of the stylesheet_link_tag in the html)
When using sassc-rails and I enter SassC in the irb console I get a NameError (uninitialized constant) (not sure whether this is useful information).
I am running out of ideas to test of what it might be...
Anybody has any idea what this might be due to ?
Thanks and kind regards,
Marcel
