我想部署一个rails应用程序到heroku，但不断收到以下错误。我曾认为管理postgres宝石将是heroku可以处理的事情。不能让rails应用程序启动heroku
我试过了所有我能想到的在我的本地机器上安装postgres的一切，如果我想安装postgres gem，我需要这样做。也没有宝石叫activerecord-postgresql-adapter ...我猜这是标准的适配器，与轨道？
有关如何解决这个问题的任何想法？

我知道这是旧的，但我现在有这个完全相同的错误。你能详细解释一下吗？你是什么意思切换到使用.gems依赖文件？ – ardavis 2011-06-03 01:21:04
这确实很旧。 .gems非常不赞成，你应该使用Gemfile。 – jonnii 2011-06-03 02:04:07
我正在使用Gemfile，我正在运行Rails 3.1。我的错误现在已经改变为初始化程序。我要发布一个新问题。以前从未见过。 – ardavis 2011-06-03 03:24:06
