“eval”已弃用。请改用“评估”

Question

最近写黄瓜功能我收到警告

[DEPRECATION] "eval" is deprecated. Please use "evaluate" instead

一切正常，但这个警告让我感到不安。我正在使用 Rails 3.1.0 和 ruby​​ 1.9.3p392（2013-02-22修订版39386）[x86_64-linux] 。我的文件是：

item.feature：

Background: logged in as an admin
Given I am logged in as an administrator

user_steps.rb

 Given /^I am logged in as an administrator$/ do
 steps %Q{
   Given the following users exist:
    | email               | password         | role       |
    | admin@test.com      | admin_password   | admin      |
    | visitor@visitor.com | visitor_password | registered |
   And I am on the "home page"
   And I follow "Login"
   And I fill in "Email" with "admin@test.com"
   And I fill in "Password" with "admin_password"
   And I press "Sign in"
   Then I should see "admin"
}
end

因此我有：

 Background: logged in as an admin            # features/item.feature:6
[DEPRECATION] "eval" is deprecated. Please use "evaluate" instead
[DEPRECATION] "eval" is deprecated. Please use "evaluate" instead
[DEPRECATION] "eval" is deprecated. Please use "evaluate" instead
[DEPRECATION] "eval" is deprecated. Please use "evaluate" instead

进入完全相同的问题。它没有破坏任何东西，它只是丑陋。

似乎代码不匹配。 Gherkin已弃用eval而赞成evaluate，而Cucumber正在调用旧方法。已经准备好拉取请求并a closed issue for this on github

直到更新Cucumber之前最快最简单的解决方案是将此行添加到您的Gemfile中：

gem 'gherkin', '<= 2.11.6'

这将迫使小黄瓜回到eval被弃用之前的时间。

修改

黄瓜宝石似乎已经更新，不再产生弃用警告。
