RSpec 找不到 Cucumber gem

Question

运行 rspec 时出现以下错误：

no such file to load -- cucumber-rails

Missing these required gems:
  cucumber-rails  

You're running:
  ruby 1.8.7.174 at /usr/bin/ruby1.8
  rubygems 1.3.5 at /home/amurmann/.gem/ruby/1.8, /usr/lib/ruby/gems/1.8

Run `rake gems:install` to install the missing gems.

我将测试环境设置为需要 rspec、rspec-rails 以及 cucumber。这些都已安装：

 - [F] has_many_polymorphs 
    - [R] activerecord 
 - [I] rspec >= 1.2.0
 - [I] rspec-rails >= 1.2.0
    - [I] rspec >= 1.3.0
    - [R] rack >= 1.0.0
 - [I] factory_girl 
 - [I] webrat >= 0.4.3
    - [I] nokogiri >= 1.2.0
    - [R] rack >= 1.0
    - [I] rack-test >= 0.5.3
       - [R] rack >= 1.0
 - [I] cucumber-rails 
    - [I] cucumber >= 0.6.2
       - [I] term-ansicolor >= 1.0.4
       - [I] treetop >= 1.4.2
          - [I] polyglot >= 0.2.5
       - [I] polyglot >= 0.2.9
       - [R] builder >= 2.1.2
       - [I] diff-lcs >= 1.1.2
       - [I] json_pure >= 1.2.0
 - [I] database_cleaner >= 0.4.3

I = Installed
F = Frozen
R = Framework (loaded before rails starts)

我已经重新安装了 cucumber 和 rspec，但错误仍然存​​在。

非常感谢您的帮助！

Answer 1

好吧，我自己弄清楚了：

我正在运行的规范文件有一个“require 'cucumber_rails'”。我不知道我是否以及为什么把它放在那里，或者它是否是由某个脚本放在那里的。我删除了这个，现在一切正常。

我不确定为什么这会导致问题，但现在它可以工作了。如果有人知道为什么这会引起麻烦，我会很高兴得到解释。

Answer 2

嗯，你确实使用了 sudo gem install cucumber-rails 来安装 gem，对吗？有时这会导致“东西”丢失。

Answer 3

我在运行稍新的 gems 的 Windows XP 上遇到了同样的问题，但大多数环境与原始帖子相同。

这就是我所做的：

1. 尝试取消注释 config.gem cucumber
2. 如果您有 config.gem cucumber，请使用 :lib =>错误的

Answer 4

伙计们，只需遵循 Wiki 说明即可。
