Rake"已经初始化了恒定的WFKV_"警告

Question

试图运行rake cucumber:ok并收到此错误:

/Users/dev/.rbenv/versions/1.9.2-p290/lib/ruby/gems/1.9.1/gems/rack-1.3.4/lib/rack/backports/uri/common_192.rb:53: warning: already initialized constant WFKV_

然后:
Command failed with status (1): [/Users/dev/.rbenv/versions/1.9.2-p290/bin...]

我是Rails的新手,谷歌没有为此错误做任何改变.

编辑:我已经尝试添加bundle exec,这没有任何区别.

这是我得到的--trace:

Answer 1

我今晚开始遇到同样的问题.它似乎与Rack 1.3.4有关.我通过将其添加到我的Gemfile来修复它:

gem 'rack', '1.3.3'

然后运行:

bundle update rack

顺便说一句,我在此之前尝试过Bozhidar的建议,但无济于事.

Answer 2

Rack 1.3.5现已推出,已修复此警告.
