歧义选项：运行Selenium，ruby脚本时收到--o（OptionParser :: AmbiguousOption）错误

Question

我正在尝试运行使用Watir，Ruby和Cucumber构建的项目，该项目以前正在处理不同版本的软件/系统详细信息。

当前系统面临的问题详细信息：

Windows 8
Cucumber version : 2.0.0
gem version : 2.4.6
Ruby version: ruby 2.2.1p85 (2015-02-26 revision 49769) [x64-mingw32]

该包正在以下配置上工作：

Windows XP/7
Cucumber 1.3.17
Gem : 2.0.14
Ruby: 2.0.0p481

当我使用rake命令运行脚本时，出现以下错误：

我试图寻找一些答案，但是看起来以前没有人遇到过。 所以，请您帮我找出问题所在
