Postgres on Rails致命错误：数据库“my_app_test”不存在

Question

我有一个新的rails环境，我正在设置，并且在运行RSPEC测试时遇到postgres连接到数据库的问题。

我的环境是红宝石2.2.4p230，Rails的3.2.22和PostgreSQL 9.4.5

我的database.yml文件看起来像：

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

我可以运行rake db:migrate，并没有收到任何错误。

我也可以运行rails c test和控制台似乎启动并显示我：

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

但是当我运行像rake db:test:prepare它看起来像它运行在终端窗口罚款，但我收到一个FATAL: database "myapp_com_test" does not exist服务器窗口。

按照同样的思路，当我运行rake spec我收到服务器窗口相同FATAL: database "myapp_com_test" does not exist这个错误

编辑： 我可以运行rails db test，它打开了数据库控制台，显示我的架构，以便测试数据库和开发数据库，​​在那里，似乎工作 - 但Postgres的似乎仍然没有找到当我由于某种原因运行rake spec时。

退房Postgres on Rails FATAL: database does not exist

尝试rake db:create:all然后rake db:migrate
