本文介绍了未初始化的常数Cucumber :: Rails :: Database（NameError）cucumber + mongoid的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我在 Gemfile
中有database_cleaner gemdatabase_cleaner，> = 0.7.2，：group => ：test
在我的 app / features / support / env.rb file我有：
require'cucumber / rails'
Capybara.default_selector =：css
ActionController :: Base.allow_rescue = false
begin
DatabaseCleaner.orm ='mongoid'
DatabaseCleaner.strategy =：truncation
rescue NameError
raiseYou需要添加database_cleaner到您的Gemfile（在：测试组）如果你想使用它。
end
Cucumber :: Rails :: Database.javascript_strategy =：truncation
当我运行 rake cucumber
我得到下一个错误：

解决方案
我有一个类似的问题，我相信它的RVM是导致问题。
基本上，Ruby编译的依赖关系;使用rvm注释
sudo apt-get install build-essential bison openssl libreadline6 libreadline6-dev curl git-core zlib1g zlib1g-dev libssl -dev libyaml-dev libsqlite3-0 libsqlite3-dev sqlite3 libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev
Hi guys I am newbie with cucumber and I have a app with mongoid.
I have database_cleaner in my Gemfile
gem "database_cleaner", ">= 0.7.2", :group => :test
In my app/features/support/env.rb file I have:
require 'cucumber/rails'
Capybara.default_selector = :css
ActionController::Base.allow_rescue = false
begin
DatabaseCleaner.orm = 'mongoid'
DatabaseCleaner.strategy = :truncation
rescue NameError
raise "You need to add database_cleaner to your Gemfile (in the :test group) if you wish to use it."
end
Cucumber::Rails::Database.javascript_strategy = :truncation
When I run rake cucumber
I get the next error:
uninitialized constant Cucumber::Rails::Database (NameError)

解决方案
I had a similar issue to this and I believe its RVM that is causing the problem.
Basically its the dependencies Ruby is compiled against; using rvm notes
sudo apt-get install build-essential bison openssl libreadline6 libreadline6-dev curl git-core zlib1g zlib1g-dev libssl-dev libyaml-dev libsqlite3-0 libsqlite3-dev sqlite3 libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev
