我将rpush gem添加到我的gemfile并运行bundle install。根据文档的下一步是运行rpush init。这给了我以下错误。

请帮忙。我已经为此工作了3天。你们很棒。
编辑：我在测试/开发环境中使用sqlite3，在生产中使用pg。
这就是我的database.yml的样子：

我尝试将我的database.yml文件从cityrails_production更改为dfvpbkpnbntg2f，但它无效。
答案 0 :(得分：2)
我在你的stacktrace中看到了rpush-1.0.0。 1.0.0很老了。请使用2.2.0
答案 1 :(得分：0)
database configuration does not specify adapter表示尚未正确设置config/database.yml文件。有关该文件中应包含的内容的详细信息，请参阅http://guides.rubyonrails.org/configuring.html#configuring-a-database。
具体而言，错误消息指向未找到adapter: <database type>
https://gist.github.com/erichurst/961978有一些database.yml的示例，您可以在设置时参考这些示例。
