Cucumber/JRuby-未初始化常量语法：：Ruby：：设置错误创建格式化程序：html（NameError）

我使用的是JRUBY/Cucumber/Watir框架，我有一个特定的features文件夹，每当我尝试使用内置HTML格式化程序时，它都会不断抛出此错误：

    uninitialized constant Syntax::Ruby::Set

使用

cucumber-1.3.14

和

jruby-1.7.10

，尽管错误发生在

jruby-1.7.4

中。支持目录中没有包含格式设置程序，也没有在

env.rb.

中的任何位置引用格式设置程序。这些格式设置程序不使用rake或运行单个功能的任何东西。奇怪的是，其他功能文件夹可以输出与失败文件夹具有相同命令参数的html报告。例如：

cucumber features/AddText.feature -f html -o report.html -f pretty 

或

任何见解都会有所帮助

更新：

---

出于某种原因，卸载“syntax”gem可以运行功能并生成html报告。我的印象是“syntax”是一个“cucumber”依赖项…

当cucumber中出现测试失败时，将向控制台写入以下行：

# gem install syntax to get syntax highlighting

不幸的是，这会导致人们安装syntax gem，这也是导致错误的原因

---

请执行“

gem uninstall syntax

”或“

sudo gem uninstall syntax

”以避免此错误。

运行“gem uninstall syntax”将正常运行

我知道这是一个有点旧的线程，但希望清除一些问题

黄瓜1.3.17和1.3.18取决于语法>=1.0.0

在目前的情况下，问题是syntax 1.2.0，而不是syntax的所有版本

所以我们应该做的是

卸载syntax 1.2.0并安装syntax 1.0.0

sudo gem install syntax -v 1.0.0

sudo gem install syntax -v 1.0.0
