Postgres on Rails FATAL：数据库“my_app_test”不存在

Question

我有一个新的rails环境我正在设置，我在运行RSPEC测试时遇到了连接到数据库的postgres的一些问题。

我的环境是Ruby 2.2.4p230，Rails 3.2.22，Postgresql 9.4.5

我的database.yml文件如下所示：

  test:
    adapter: postgresql
    encoding: unicode
    database: myapp_com_test
    min_messages: WARNING
    pool: 5
    username: 
    password: 

我可以运行rake db:migrate并且不会收到任何错误。

我也可以运行rails c test并且控制台似乎启动并向我显示：

Digest::Digest is deprecated; use Digest
Loading test environment (Rails 3.2.22)
[1] pry(main)>

但是当我运行类似rake db:test:prepare它看起来好像在终端窗口中运行正常，但我收到一个FATAL: database "myapp_com_test" does not exist在服务器窗口FATAL: database "myapp_com_test" does not exist 。

沿着相同的路线，当我运行rake spec我收到相同的FATAL: database "myapp_com_test" does not exist在服务器窗口FATAL: database "myapp_com_test" does not exist以及此错误

有什么想法在这里发生了什么？

编辑：我可以运行rails db test并打开数据库控制台并向我显示架构，以便测试数据库和开发人员数据库在那里并且似乎正在运行 - 但是当我运行rake spec时，Postgres似乎仍然没有找到它由于某些原因。

查看Postgres on Rails FATAL：数据库不存在

尝试使用rake db:create:all然后使用rake db:migrate
