该应用程序似乎正在运行，但我的日志中出现了这些错误。此问题显示在每个页面加载时的“/favicon.ico”、“/assets/application-34baf7d108c7408a8c110454dc57e8f6.js”和“/assets/application-e6b66fbbea8acd5eddb9fada1fa91c36.css”的日志中。

此外，这个问题不会在开发中发生，只会在 heroku 上发生。

而且，即使它说的是 ruby​​/1.9.1，我也只是检查了“heroku run ruby​​ -v”并确认我正在运行“ruby 1.9.3p392（2013-02-22 修订版 39386）[x86_64-linux]”

我摆脱了错误，我在我的 config/enviroments/production.rb 中做了这个

-  config.assets.compile = false
+  config.assets.compile = true

作为解决方案的替代方案，您可以在本地编译资产，然后将它们发送到 heroku...

$ rake assets:precompile
$ git add -A
$ git commit -m 'compiled assets'
$ git push heroku master

我这样做是 CI 步骤的一部分
