部署heroku应用程序时，我得到推拒绝错误（预编译资产失败）

Question

这是我试图推上heroku的应用程序：https://github.com/kunokdev/flightmap但是我得到Precompiling assets failed错误和Push rejected to ...日志。什么可能导致这个？

remote:  /tmp/build_b9c70fb95f66f6b57f7d5868507a42de/vendor/bundle/ruby/2.2.0/gems/sprockets-rails-3.0.4/lib/sprockets/rails/task.rb:67:in `block (2 levels) in define'

正如@ 7urkm3n建议终端命令RAILS_ENV=production bundle exec rake assets:precompile解决了这个问题。
