Heroku rake资产:预编译无法编译Rails应用程序

我没有对我的资产进行任何更改,现在突然间,当我执行git push heroku master时,它会对rake资产中止:precompile

...

它看起来像是在资产/样式表/ application.css.scss中错误的参数数量(2比1).但我的样式表中没有任何方法.这是那个文件:

/*
* This is a manifest file that'll be compiled into application.css, which will include all the files
* listed below.
*
* Any CSS and SCSS file within this directory, lib/assets/stylesheets, vendor/assets/stylesheets,
* or vendor/assets/stylesheets of plugins, if any, can be referenced here using a relative path.
*
* You're free to add application-wide styles to this file and they'll appear at the top of the
* compiled file, but it's generally better to create a new file per style scope.
*
*= require_self
*= require_tree .
*/

在我的assets/stylesheets/custom.css.scss中,我在顶部有这个:

@import 'bootstrap';
@import 'bootstrap-responsive';

在我的config/application.rb文件中,我有:

config.assets.precompile += %w(*.png *.jpg *.jpeg *.gif)
config.assets.initialize_on_precompile = false

我已经执行了一个heroku运行rake资产:clobber,但没有帮助.

本地我的应用程序工作和功能完美.

这是我用来参考的一些宝石:

gem 'sass-rails'
gem 'bootstrap-sass', '2.3.2.0'
gem 'rails_12factor'
gem 'compass_rails'
gem 'jquery-rails'
gem 'rails', '4.0.2'

有任何想法吗？

好.我发现了问题.

gem'sass-rails'使用的是版本3.2.14.通过更新到4.0.2,我可以在部署到Heroku时预编译我的资产.

一切都很好.
