You have a sass-rails gem in your Gemfile. You need to change the version of sass-rails to '5.0.0.beta1'. And then run bundle update sass-rails rails.

你的Gemfile中有一个sass-rails gem。您需要将sass-rails的版本更改为“5.0.0.beta1”。然后运行bundle update sass-rails rails。

You could find some useful info at this sprockets-rails issue.

您可以在此sprockets-rails问题上找到一些有用的信息。

P.S.: Moreover I have the same problem with rails_admin which I reported here.
