“未找到或不可读的要导入的文件：实现”：在 Rails 中实现 CSS

Question

我正在尝试在 Rails 项目中使用 Materialize CSS 框架，但遇到以下错误：

File to import not found or unreadable: materialize. Load paths:

应用程序.scss

/*
*= require_tree .
*= require_self
*= require font-awesome
*/

// "bootstrap-sprockets" must be imported before "bootstrap" and "bootstrap/variables"

@import "materialize";
@import "bootstrap-sprockets";
@import "bootstrap";

应用程序.js

//= require jquery
//= require jquery_ujs
//= require materialize-sprockets
//= require bootstrap-sprockets
//= require turbolinks
//= require_tree .
//= require jquery.infinitescroll

我确实安装了Materialise gem。我收到错误是因为我已经安装了引导程序吗？提前致谢！

添加 gem 后，您应该重新启动服务器。
