我的style.scss.css文件:
@import 'bootstrap';
我已经包含了javascript文件,但没有任何变化.不知道为什么会这样,有什么想法吗？
更新
找到一个临时解决方案:https://github.com/twbs/bootstrap-sass/issues/560
只需要通过将其添加到gem文件来强制sprockets版本:
gem 'sprockets', '=2.11.0' #force for now
这将立即解决它
将rails从4.0.3升级到4.0.4后,我也遇到了完全相同的错误.
要解决这个问题,只需添加
gem "sass-rails", "~> 4.0.2"
到你的Gemfile然后
bundle install
最后重启rails服务器
然后在rails 4.0.4中享受编程
升级到Rails 4.0.5时,需要暂时将链轮锁定在2.11.x:
gem 'sprockets', '<= 2.11.0'
然后
bundle install
我得到的确切错误是:
ActionView::Template::Error: undefined method `environment' for nil:NilClass
