Rails资产预编译：jquery.scrollbar.css背景图像中的CSS无效

Question

在部署我的Rails应用程序的资产预编译阶段，我收到以下错误：

Sass::SyntaxError: Invalid CSS after "...round: url(data": expected comma, was ":image/svg+xml;..."
(in  /.../workshop/app/assets/stylesheets/application.css)
(sass):13673

有罪的CSS是第二个背景定义，其中包含背景图像的URL。我该如何解决这个问题？

.scrollbar-light > .scroll-element .scroll-element_size {
background: #dbdbdb;

url需要引用...
