我无法在 Google 或 stackoverflow 上的其他任何地方找到这个确切的错误。
我正在运行 Rails 4.1.0 和 rspec-rails 3.0.0.beta2
尝试运行 $rspec 时，出现以下错误：

该错误是由 spec_helper.rb 中的“require 'rspec/rails'”生成的。
我不明白为什么会发生这种情况，因为我在 database.yml 中正确配置了我的测试数据库：
default: &default
host: localhost
adapter: postgresql
encoding: unicode
pool: 5
timeout: 5000
development:
<<: *default
database: innovacert_development
username: <%= ENV['DATABASE_USER'] %>
password: <%= ENV['DATABASE_PASS'] %>
# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
<<: *default
database: innovacert_test
username: sam
password:
从这一行：
/Users/sam/.rvm/gems/ruby-2.1.1/gems/activerecord-4.1.0/lib/active_record/connection_adapters/connection_specification.rb:257:in `resolve_symbol_connection': 'development' 数据库未配置。可用：["test"] (ActiveRecord::AdapterNotSpecified)
IT 似乎 rspec 正在尝试寻找一个名为 :development 的数据库。然而在 spec_helper.rb 我明确定义：
ENV["RAILS_ENV"] ||= "测试"
我用 pry 来查看这个变量，它肯定被分配为“测试”。
为什么 rspec 失败了？
