I used Rails Composer to create a skeleton application for the rails-devise-roles project described here:
https://github.com/RailsApps/rails-devise-roles
I'm getting a 500 error generated by the following:
Sass::SyntaxError - ".authform form" failed to @extend ".bg-faded".
The selector ".bg-faded" was not found.
Use "@extend .bg-faded !optional" if the extend should be able to fail.
Adding the "!optional" flag allows it to render, but none of the navigation links are then displayed.
Contents of my Gemfile are displayed below:
source 'https://rubygems.org'
git_source(:github) do |repo_name|
repo_name = "#{repo_name}/#{repo_name}" unless repo_name.include?("/")
"https://github.com/#{repo_name}.git"
end

Thoughts?
将@extend .bg-faded
@extend .bg-light
更改为@extend .bg-light
将修复您的错误
Its most likely because you haven't imported the framework CSS. Add these to your application.scss file
// import the CSS framework
@import "bootstrap";
将gemfile中的bootstrap行更改为gem'bootstrap gem 'bootstrap', '= 4.0.0.alpha6'
