ruby-on-rails - spring rspec连接不上数据库

Question

我有一个新的 Rails 5 应用程序。我按照说明安装了 spring 和 spring-commands-rspec gem。我可以自己运行 rspec 并且测试运行良好。但是，如果我运行 Spring binstub bin/rspec 我会得到这个:

Running via Spring preloader in process 227
/usr/local/bundle/gems/activerecord-5.0.0.1/lib/active_record/connection_adapters/postgresql_adapter.rb:671:in `initialize': could not connect to server: No such file or directory (PG::ConnectionBad)
    Is the server running locally and accepting
    connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?
    from /usr/local/bundle/gems/activerecord-5.0.0.1/lib/active_record/connection_adapters/postgresql_adapter.rb:671:in `new'
    from /usr/local/bundle/gems/activerecord-5.0.0.1/lib/active_record/connection_adapters/postgresql_adapter.rb:671:in `connect'
    from /usr/local/bundle/gems/activerecord-5.0.0.1/lib/active_record/connection_adapters/postgresql_adapter.rb:217:in `initialize'
    from /usr/local/bundle/gems/activerecord-5.0.0.1/lib/active_record/connection_adapters/postgresql_adapter.rb:37:in `new'
    from /usr/local/bundle/gems/activerecord-5.0.0.1/lib/active_record/connection_adapters/postgresql_adapter.rb:37:in `postgresql_connection'
    etc...

我有一个使用 binstubs 和 bin/rspec 的 Rails 4 应用程序，效果很好。给了什么？

顺便说一句，rake spec 以同样的方式失败，出现数据库连接错误。

Answer 1

尴尬。我没有正确设置我的 database.yml 以从 *default 继承设置，所以上面的消息字面意思是告诉我没有数据库在运行。修复后，binstub 再次工作。
