File not found: /app/styles/app.scss

I get the following error when booting my app after installing any ember-cli-mdc module.

Build Error (SassCompiler)

File not found: /app/styles/app.scss
in any of the following include paths:
  /var/folders/j3/ch6_9v7s41j8n13m96s7smfc0000gp/T/broccoli-328852ZG8VR9MaAox/out-528-broccoli_merge_trees
  node_modules
  app/styles

I am running ember 3.7.1 I am using ember-cli-sass, I have a /app/styles/app.scss file and the following in my ember-cli-build.js

sassOptions: {
  extension: 'scss',
   includePaths: ['node_modules']
},

Any recommendations?

update: removing ember-cli-sass seems to have fixed the problem

@jamesstaub First, thank you for your interest in using the project. If you are using it for any public product, it would be good to know so we can track how ember-cli-mdc is being used. Second, I was going to suggest removing ember-cli-sass from your project. ember-cli-mdc has its own integration of the sass compiler because ember-cli-sass does not work well with material-components-web. When using ember-cli-sass, it take about 30 second to 2 minutes for your project to recompile for each change if you have live updates enabled. We worked really hard to resolve this problem so you get the same experience you are used to when using ember-cli-mdc.

With all that being said, I will update the README.md with this notice/warning, and update the build engine to print an error message and stop if you have ember-cli-sass installed.

Thanks for the info, and for your work on this package! My company is trying this package for a customer-facing product but it is not yet public. We were drawn to this package over ember paper because paper does not implement the most recent version of material design components.

I am facing the same slow re-compile issue in my app when i directly tried to use material-components-web with ember-cli-sass. @hilljh82 Could be please shed some light on why it is taking more than 30sec-1min to recompile? How do you solve the issue by building ember-cli-mdc-sass ? It would be really helpful to understand the scenario.
