It is a simple memorandum. This is an error while implementing rails6 with docker.
docker 2.3 rails 6.0.3 Ruby 2.6.5
SassC :: SyntaxError and'materialize-sass' gem is not loaded.
gem 'materialize-sass' gem 'material_icons'
Bundle install in container but still error why. .. ??
I rebuilt it because there are cases where the cache remains.
docker-compose build --no-cache
