推荐答案

你有一个 sass-rails gem 在您的 Gemfile 中.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 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.

您可以在 这个 sprockets-rails 找到一些有用的信息问题.

PS:此外，我报告的 rails_admin 也有同样的问题此处.
