Question

我正在尝试将rails应用程序部署到heroku，但不断收到以下错误。我曾经想过，管理postgres宝石将是heroku将要处理的事情。

我已经尝试了一切我能想到的在我本地机器上安装postgres的一切，如果我想安装postgres gem，我需要这样做。还有没有名为activerecord-postgresql-adapter的宝石...我猜这是轨道附带的标准适配器？

有关如何解决这个问题的想法吗？

Answer 1

Upgrade your Gemfile to Bundler 0.9并添加pg宝石。很简单。

Answer 2

事实证明这是一个错误，因为在heroku和我的机器上运行的bundler版本不同。我已经切换到使用.gems依赖文件，一切似乎都在运行。

Answer 3

有关Heroku捆绑支持的详细信息，请访问：http://docs.heroku.com/bundler

Heroku要求您指定'pg'gem。

Answer 4

哇我现在已经做了同样的事情太久了..

我意识到我使用的是宝石'ps'而不是'pg'
