我在 Hudson CI 中有一个损坏的构建，我不确定如何修复。问题似乎很简单——加载了不正确的 gem 版本——但 Hudson 控制台输出似乎与错误消息相矛盾。

Hudson 的console构建输出：

[...hudson fetching code from SCM...]

因此，该bundle install命令显示launchy (2.1.0)正在使用，但错误表明launchy 0.3.7已激活。我不确定哪里有这种差异/冲突。

如您所见，我们正在使用bundle exec运行构建，因此应该应用捆绑包，所以我不确定这里发生了什么。

在 hudson 项目配置的“Build => Execute shell”部分，我有以下三行，这就是全部：

export RAILS_ENV="hudson"
bundle install
bundle exec rake hudson:all --trace

Gemfile拥有：

...
group :development, :cucumber, :test,:hudson do
  gem "populator",  ">= 0.2.5"
  gem "factory_girl",">= 1.2.1"
  gem "faker", ">= 0.3.1"
  gem "rspec", "1.3.2"
  gem "rspec-rails", "1.3.4"
  gem "webrat"  
  gem "capybara"
  gem 'launchy'
  gem "cucumber","1.1.8"
  gem "cucumber-rails","0.3.2"
  gem "database_cleaner"
  gem "ruby-debug"
end
...

Gemfile.lock有：

  specs:

    launchy (2.1.0)

显然答案在这个链接中。不知道我在谷歌搜索时是如何错过这个答案的：

基本上，为您的应用创建自定义 gemset + 按照文章中的说明进行操作。
