我面临一个奇怪的问题。我使用sharetribe在Rails上工作，并更改了文件中的某些值。当我执行“ git push heroku master”时，我知道得到了我之前没有的错误：
Could not detect rake tasks
remote: ! ensure you can run `$ bundle exec rake -P` against your app
remote: ! and using the production group of your Gemfile.
remote: ! rake aborted!
remote: ! ArgumentError: invalid number of elements (3 for 1..2)

即使我变回更新的文件，也仍然会出现错误...我不在本地获取它。你知道我该如何处理吗？
我正在使用rails 2.4.4。非常感谢
