我的 Rails 3 应用程序中的 Metric-fu 无法运行

Question

通过将其放入我的 Gemfile 中，在 Rails 3 应用程序中安装了 metric-fu。但是当我运行 rake 任务时它失败了。以下错误，有人知道如何解决这个问题吗？

Answer 1

该行在最新版本的 metric_fu 中已更改，因此我建议升级到最新的宝石： http://rubygems.org/gems/metric_fu/versions/2.1.1< /a>

通过这一更改，您至少不会收到与 chr 未定义相关的致命错误。

Answer 2

问题是 Ruby 1.9，我报告了一个问题，并且几乎立即得到回复，说问题不是 metric_fu 而是一些不理解 1.9 语法的指标

https://github.com/jscruggs/metric_fu/issues/72

Answer 3

我安装了 metrical 作为 metric_fu 的包装器，并且正在运行 Rails 3.1rc4 和 Ruby 1.9.2，

我遇到了一堆错误，这些错误阻止了任何事情的发生，在谷歌搜索后发现其他人说他们通过删除 rcov、reek、flog 得到了结果和 flay 所以我做了同样的事情，但实际上我发现通过一次添加一个，实际上只有鞭打才导致这个错误是致命的。因此，我建议将 .metrics 文件添加到 Rails 应用程序的根目录中 - 这是我的：

MetricFu::Configuration.run do |config|  
#   config.metrics -= [:rcov]  
#   config.metrics -= [:reek]  
#   config.metrics -= [:flay]  
  config.metrics -= [:flog]
end  

现在工作正常，我几乎完全覆盖了 metric_fu。

Answer 4

我认为这是一个 rcov 问题。 Ryan 在 Railscast 中提到了这一点

# Gemfile
gem "simplecov", :require => false, :group => :test

# .metrics
MetricFu::Configuration.run do |config|
  config.metrics -= [:rcov]
end

http://railscasts.com/episodes/252-metrics -metrics-指标

Answer 5

我是 metric_fu 的新维护者，它现在应该可以正常工作了。请参阅配置说明 https://github.com/metricfu/metric_fu

另外，它可以通过命令运行 -现在就行。现在需要捆绑它或运行 rake 或 metrical
