 2014- 11-26T21：12：41.561471 + 00：00 heroku [web.1]：状态从开始变为崩溃


解决方案

我通过运行修复了这个问题：

bundle update backports



并确保我的Gemfile.lock已更新并提交。


I'm trying to deploy Dashing to Heroku. Everthing runs perfectly on localhost. Deploying with the instructions provided by the github page

It seems to be something to be with the backports gem.

Below are the heroku log files

2014-11-26T21:12:41.561471+00:00 heroku[web.1]: State changed from starting to crashed

解决方案
