Question

我有这个问题，当我尝试推送到Heroku时，我得到的错误是

!     Precompiling assets failed.

!     Push rejected, failed to compile Ruby app

Answer 1

precompiling-assets

在config.assets.initialize_on_precompile = flase

中设置config/application.rb

Heroku要求这是假的

Answer 2

好吧，如果您使用rails 4x，则根本不需要为Heroku更改任何配置文件。

你所要做的就是添加这个宝石：

gem 'rails_12factor', group: :production

它会更改您的配置以符合Heroku对您的要求。如果这不起作用，我会仔细检查我的application.css或application.js是否需要不存在的资产。尝试在本地编译资产。

Heroku上的Ruby on Rails资产预编译失败
