Rails 3 - 移动到/启动生产服务器 - 生产数据库未配置？

Question

我正在寻找部署我的第一个rails应用程序，并且遇到了一些问题。首先，开发服务器中的一切正常，所以我觉得我很好走。在将应用程序部署到我的主机失败后，我尝试第一次以生产模式启动服务器，并收到了一些错误。

出于好奇，我创建了一个新的应用程序，完全新鲜，没有我编辑任何代码。我得到几乎与我的数据库相同的错误：

有没有人在尝试启动生产服务器时遇到此问题？该database.yml的，只是良好的措施，是sqlite3的下列默认：

production: 
    adapter: sqlite3 
    database: db/production.sqlite3 
    pool: 5 
    timeout: 5000 

我核实.yml没有标签（不，它应该自动生成）。

无论如何，我很感激帮助。

你安装了sqlite3的宝石吗？听起来像它找不到适配器。
