每天结束时，我都会在 RoR 环境中运行 metric_fu 来衡量代码质量。直到今天一切正常...

当我尝试运行 metric_fu 时，这是我从今天开始的结果。

$ bundle exec metric_fu -r

我在这里发现了一个类似的问题：https ://github.com/jscruggs/metric_fu/issues/61 。由于 GitHub 上的问题，我在项目的根目录中创建了一个名为“.metrics”的文件，内容如下：

MetricFu::Configuration.run do |config|   
  config.syntax_highlighting = false
end

不幸的是，这没有用。

最近几天除了代码没有更新，这就是为什么突然出现这个错误很奇怪。

这是我的 Ruby 版本：

$ ruby -v
ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-darwin11.4.0]

提前致谢！

可以通过禁用流失来绕过该问题。您可以通过添加来禁用流失--no-churn，如下所示：

$ metric_fu -r --no-churn

由于我添加了--no-churn一次，Metric_fu 再次完全可操作。即使在下一个报告中激活了流失，同时分析了相同的代码。

请在 metric_fu 问题页面上输入一个问题 （那里有旧仓库的链接）。根据堆栈跟踪，这实际上可能是 Churn 中的一个问题（metric_fu 没有处理）。另请查看我的如何编写错误报告页面 ，我将与您一起解决那里的错误。

有趣的是，我还没有遇到它崩溃的项目或文件的任何其他细节？我可以尝试在流失中调试它，但没有太多事情要做。您可以直接提交 metric_fu 问题或 churn 问题。我关注这两个项目，所以我会尝试在任何一种情况下跟进。
