Question

我已经在https://github.com/cucumber/cucumber-rails#installation

之后将cucumber-rails gem安装到新的Rails 4应用程序中

但是当我尝试运行它时会发生错误：

biske@biske:~/bla$ cucumber

这个错误抱怨来自features / support / env.rb文件的第7行，即：

require 'cucumber/rails'

这里有什么问题？

Answer 1

在将cucumber-rails版本升级到1.3.15之后，我遇到了这个问题。

首先重新生成黄瓜配置（特别是如果你最近更新了一些宝石）：

rails g cucumber:install

如果没有帮助尝试使用命令在捆绑器中运行黄瓜：

bundle exec cucumber

或更方便且技术上相同的命令（在我的情况下在rails 4.1.1上工作）：

rake cucumber

详细了解“bundle exec”命令前缀：Use bundle exec rake or just rake?

Answer 2

cd进入features文件夹，然后尝试运行cucumber your_feature_name.feature

Answer 3

在我的情况下，问题是我在功能/支持中使用的文件env.rb需要一个它不应该存在的文件，或者不存在的文件。

因此，请检查features / support / env.rb，尽可能多地编辑，看看是否有帮助。

黄瓜无法加载这样的文件 - rails（LoadError）
