ruby-on-rails - Rails调试 Assets :precompile: how to identify offending file(s)?

Question

我有点绝望。数天以来一直在尝试调试此问题。有人知道如何解决吗？也许找出造成编码问题的文件？

FWIW:这在开发环境中有效:RAILS_ENV=production bundle exec rake assets:precompile --trace
但这在“生产”服务器上失败了……不知道如何开始故障排除:

$ RAILS_ENV=production RAILS_GROUPS=assets bundle exec rake assets:precompile --trace
** Invoke assets:precompile (first_time)
** Invoke assets:environment (first_time)
** Execute assets:environment
** Invoke environment (first_time)
** Execute environment
** Execute assets:precompile

我将开始一个循环，从 list 中删除文件，然后尝试进行部署。如果那不起作用，我将从 list 中删除下一个文件，依此类推，直到找到导致该问题的文件。
