【问题描述】：

我在暂停后继续测试我的 rails 应用程序。现在在我的 rails 应用程序上运行测试会返回 SystemStackError。即使是像

这样的简单测试

def test_per_page

assert_instance_of Fixnum, Activity.per_page

结束

给我

C:/Ruby/lib/ruby/gems/1.8/gems/activesupport-2.3.2/lib/active_support/core_ext/m odule/introspection.rb:74:in `local_constants': 堆栈级别太深（SystemStac 错误）

我发现我们已经安装并删除了 test-unit gem。即使在那之后，同样的问题不断出现。我在使用 rcov 的同时也安装了 rcov 和同样的东西..

以前有没有人遇到过这样的事情..我知道 gem require 被一遍又一遍地调用..有没有办法解决这个问题？

【问题讨论】：

我尝试创建一个新项目并在同一系统上编写一个简单的单元测试，它就像一个魅力......所以我猜问题出在我安装的一个插件上。 .而且每次我开始运行测试时，这个警告首先出现.. C:/Ruby/lib/ruby/gems/1.8/gems/rails-2.3.2/lib/rails/gem_dependency.rb:99:Warning: Gem:: Dependency#version_requirements 已弃用，并将在 2010 年 8 月或之后删除。使用 #requirement 我使用 gem update --system 更新了 gem，但仍然给我同样的错误。提前感谢所有帮助...

【参考方案1】：

哎呀！当环境启动时，我有两个为 rcov 运行的初始化程序。一个在 environment.rb 文件中，另一个在 config 文件夹的 env 子文件夹中的单独的 test.rb 文件中。所以它一直在不断地循环下去。无论如何问题都解决了，地球还在旋转。

谢谢
