我正在尝试运行轨道（4.1.2） 安慰
rails c RAILS_ENV=test
我得到这个：
> config.eager_load is set to nil. Please update your
> config/environments/*.rb files accordingly:
>
> * development - set it to false * test - set it to false (unless
> you use a tool that preloads your test environment) * production -

> /Users/xxxxxx/.rvm/gems/ruby-2.2.2/gems/activerecord-4.1.12/lib/active_record/connection_adapters/connection_specification.rb:257:in
> `resolve_symbol_connection': 'RAILS_ENV=test' database is not
> configured. Available: ["development", "test", "production"]
> (ActiveRecord::AdapterNotSpecified)
然而在我的test.rb I have config.eager_load = false and my database.yml没问题（我跑了rake db:schema:load RAILS_ENV=test没有问题。
我该如何解决这个问题？
您需要在运行命令之前声明环境：
RAILS_ENV=test bundle exec rails c
我在我的计算机上得到相同的输出：
> bundle exec rails c RAILS_ENV=test ian@Ians-MacBook-Pro
config.eager_load is set to nil. Please update your config/environments/*.rb files accordingly:
* development - set it to false
* test - set it to false (unless you use a tool that preloads your test environment)
* production - set it to true
但是当我按照建议运行时：
> RAILS_ENV=test bundle exec rails c ian@Ians-MacBook-Pro
