Question

我是Ruby on Rails的新手。执行Michael Hartl的Ruby on Rails教程。

我使用Cloud 9作为主机，使用Bitbucket进行版本控制，并通过Heroku进行部署。我试图将Postgresql安装到我的项目而不是sqlite3，因为我知道Heroku需要它。但不知何故，在我的文件中某处我失败了。

有人可以帮忙吗？

当我跑步时：

$ git push heroku master

我收到此错误：

如错误所述，您无法在Heroku上使用sqlite3。

错误意味着您的Gemfile包含sqlite3作为生产捆绑过程的一部分。您需要做的是将sqlite3包裹在development和/或test组中，并确保在这些组之外拥有pg gem。
