无法推送到Heroku:Sprockets :: FileNotFound:找不到application.css

Question

我曾经能够毫无问题地推向Heroku.在做了一些似乎与我的问题无关的更改后,它无法推送到Heroku.在git push heroku我得到的错误:

...
remote: -----> Preparing app for Rails asset pipeline
remote:        Running: rake assets:precompile
remote:        rake aborted!
remote:        Sprockets::FileNotFound: could not find file: /tmp/build_c657fd7***e8c75a3/app/assets/stylesheets/application.css
remote:        /tmp/build_790d1e***cab4395/vendor/bundle/ruby/2.2.0/gems/sprockets-3.3.3/lib/sprockets/loader.rb:103:in `load_from_unloaded'
remote:        /tmp/build_790d1***ab4395/vendor/bundle/ruby/2.2.0/gems/sprockets-3.3.3/lib/sprockets/loader.rb:60:in `block in load'
...
remote:  !     Precompiling assets failed.
remote:  !     Push rejected, failed to compile Ruby app
remote:  !     Push rejected to ***.

application.css 确实存在于我的开发环境中,包括:

 *= require_self
 *= require universal
 *= require bootstrap-datepicker3
 *= require menu_header
 *= require table
 *= require wice_grid
 *= require_tree .

有没有人知道可能导致问题的原因以及该怎么办？如果我可以通过重置某些东西来解决它,那么这是一个选项,因为应用程序尚未生效,因此不存在丢失数据的风险.

我联系了Heroku,他们将其描述为一个slug缓存问题.使用purge_cache清除缓存解决了它.
