我使用 jenkins 的主/从来并行运行用 rspec 编写的测试用例。在每个slave中，我设置了8个executor，每个executor会同时运行这样的命令：gem install bundler & bundle install & rake rspec ...
执行“捆绑安装”时发生随机错误，所有错误都是关于“无法加载此类文件--- <%file_name%>”。这个随机错误频率非常低（大约 50 次 bundle install 发生一次），而错误中的 <%file_name%> 则完全不同：这次是“bundler/index”，而那个时间可以是另一个，例如“捆绑商/供应商”。
我不确定它是否是由并行运行“捆绑安装”引起的。有没有人遇到类似的问题？
这是我的环境：
每个slave的操作系统：CentOS release 6.3 (Final)
Ruby 版本：ruby 1.9.3p125（2012-02-16 修订版 34643）
捆绑器版本：1.3.5
Rspec 版本：2.12.2
RVM 版本：1.18.20（稳定）
宝石版本：1.8.25
以下是这些随机错误之一：
