ruby-on-rails - 从1.9.1-> 1.9.3开始，将Rails App部署到Heroku时崩溃，不确定由什么组成的日志

Question

好的，我放弃了，需要您的帮助。 My Rails应用程序在Heroku上崩溃并曾经在1.9.3之前运行。我已经完成了1.9.3的所有更改，甚至创建了一个新应用程序，但它始终会崩溃。在本地工作正常。以下是heroku日志中的内容:

Answer 1

好吧，我已经解决了。日志中的线索是:

2013-01-09T03:01:08+00:00 app[web.1]: /app/vendor/bundle/ruby/1.9.1/gems/railties-3.1.10/lib/rails/commands/server.rb:33:in `parse!' (OptionParser::InvalidArgument)

这表明瘦Web服务器无法从传递的参数开始。基于以下内容:https://devcenter.heroku.com/articles/rails3，我将procfile从以下位置更改:

web: bundle exec rails server thin -p $PORT

对此:

web: bundle exec rails server thin -p $PORT -e $RACK_ENV

并使用以下命令将RACK_ENV设置为在我的环境中暂存:

$ echo "RACK_ENV=development" >>.env

现在，它可以解决其他问题。
