我有一个破碎的构建哈德森CI，我不知道如何解决。问题看起来非常简单 - gem的不正确版本被加载 - 但Hudson控制台输出似乎与错误消息相矛盾。哈德森加载错误版本的宝石构建
哈德森的console输出编译：

因此，bundle install命令显示正在使用launchy (2.1.0)，但错误说launchy 0.3.7已被激活。我不确定哪里存在这种差异/冲突。你可以看到，我们使用bundle exec来运行构建，因此应该使用这个包，所以我不确定这里发生了什么。
在哈德森项目配置的 “构建=>执行壳” 部分，我已经下面三行，这是所有：
export RAILS_ENV="hudson"
bundle install
bundle exec rake hudson:all --trace
Gemfile具有：
...
