未初始化的常数Cucumber :: Rails :: Database（NameError）cucumber + mongoid [英] uninitialized constant Cucumber::Rails::Database (NameError) cucumber + mongoid

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
