Question

当我尝试运行一些ruby单元测试时，我遇到了问题。

我在哈德森得到以下堆栈：

/home/cpcaserver5/.rvm/gems/ruby-1.9.2-p290/gems/rake-0.9.2.2/lib/rake/ext/module.rb:36:in `const_missing': uninitialized constant Time::DATE_FORMATS (NameError)

Rails支持多种日期格式，通常在initializers / time.rb中的初始化程序中声明 - 例如：

Date::DATE_FORMATS[:short_date] = "%b %d, %Y"
Date::DATE_FORMATS[:full_date] = "%A, %B %d, %Y"
Time::DATE_FORMATS[:short_slashed] = "%m/%d/%Y %I:%M %p"
Time::DATE_FORMATS[:short_date] = "%b %d, %Y"

这允许date.to_s（：short_date）格式化日期输出。但是，您的错误输出表明此文件尚未被读取，并且由于我没有看到任何指示堆栈跟踪中的rails的输出，我想知道是否已加载任何rails文件。

'const_missing'：未初始化的常量Time :: DATE_FORMATS（NameError）
