Ruby 耙；已初始化常数WFKV“；警告

尝试运行

rake cumber:ok

时，我收到以下错误：

/Users/dev/.rbenv/versions/1.9.2-p290/lib/ruby/gems/1.9.1/gems/rack-1.3.4/lib/rack/backports/uri/common192.rb:53:警告：已初始化常量WFKV齌

然后：

命令失败，状态为（1）：[/Users/dev/.rbenv/versions/1.9.2-p290/bin…]

我是Rails的新手，谷歌并没有发现这个错误

编辑：我已经尝试添加了

bundle exec

，但没有任何区别

以下是我通过

--trace

任务：TOP=>cumber:ok

我今天晚上开始有同样的问题。它似乎与机架1.3.4有关。我通过将以下内容添加到我的文件中来修复它：

gem 'rack', '1.3.3'

然后运行：

bundle update rack

顺便说一句，在此之前我试过博日达的建议，但没有效果。

因此，我包括：

需要“uri/common”；：：URI.send:remove_const，：WFKV_

---

然而，“它将在Gemfile中工作”的注释实际上应该是“必须在Gemfile中工作。”

Rack 1.3.5现已发布，它修复了此警告。

您应该卸载rake-0.9.2 并安装机架1.6.13

gem uninstall rake
gem install  rack 1.6.13

---

从common_192.rb中的评论（“从ruby core的uri/common.rb@32618ba中窃取，以修复1.9.2中的DoS问题”和“一旦ruby 1.9.2修补程序级别包含此修复程序，可能应将其删除”）来看，这似乎是为了防止拒绝服务攻击而添加到机架中的。它故意在Ruby中修补漏洞，但monkeypatch会导致“已初始化常量”警告。因此，看起来我们要么按照Daniel的建议恢复到1.3.3，要么得到修复并忍受警告一段时间。在我的例子中，警告是防止资产管道预编译，所以恢复到1.3.3是唯一的选择。对此已经添加了一个修复-因此应该在rack的下一个版本中。如果出于某种原因您确实需要rack 1.3.4，您可以执行类似于

require'uri/common'；：：URI.send:remove_const，：WFKV

在需要机架之前。它甚至可以在您的GEM文件中工作。只是一个小提示：我不会进行捆绑包更新，而是

捆绑包更新机架

<代码>捆绑更新将要更新所有gem。
