我是Ruby on Rails的新手。我试图制作一个“Hello，world！”网络应用程序遵循Hartl的教程，但我无法在Heroku上部署该应用程序。我已将文件添加到git，并提交了它们。此外，该应用程序在我的本地计算机上运行良好。
以下是我运行git push heroku master时得到的结果： -
[jobsism10-Lenovo-G580]: ~/Downloads/Web Development/Rails Projects/hello_app$ git push heroku master

gem 'uglifier', '2.5.3'
# Use CoffeeScript for .coffee assets and views
gem 'coffee-rails', '4.1.0'
# See https://github.com/sstephenson/execjs#readme for more supported runtimes

group :development, :test do
# Call 'byebug' anywhere in the code to stop execution and get a debugger console
gem 'byebug','3.4.0'
# Use sqlite3 as the database for Active Record
gem 'sqlite3','1.3.9'
# Access an IRB console on exception pages or by using <%= console %> in views
gem 'web-console', '2.0.0.beta3'

gem 'spring', '1.1.3'
end
group :production do
gem 'pg', '0.17.1'
gem 'rails_12factor', '0.0.2'
end
有人可以帮我解决这个问题吗？
答案 0 :(得分：4)
正如此question
所述只需运行：bundle update sass-rails
最终将你的sass-rails gem更新为最新版本。或者您可以在宝石文件中输入高于5.0.1的版本。
5.0.1 sass-rails版本似乎存在问题
