黄瓜无法加载2.1 / gherkin_lexer_en

问题描述

每当我运行黄瓜功能，我得到以下错误。
然而，脚本工作正常，但此警告消息每次我执行功能文件时出现。这里有什么问题？

  C：\Automation\PickLists\Activities\2.RemoveActivity> cucumber 
警告：无法加载这样的文件 -  2.1 / gherkin_lexer_en

解决方案

捆绑安装后，删除gherkin gem：

  -force 
  

重新安装gem（可能需要一些时间）：

  gem install gherkin --platform ruby​​ -v 2.12.2 
  

转到ruby安装目录中的gem文件夹。像这样：

  {ruby_dir} \lib\ruby\gems\2.1.0\gems\ gherkin-2.12.2\lib\gherkin 
  

并替换 lib /gherkin/c_lexer.rb 第7行与：

  prefix =''

我必须在Windows操作系统上安装每个软件包后执行这些步骤。已使用Windows 7和Windows 10测试。
 
I am getting the following error whenever i run cucumber feature.
However, the script works fine but this warning message appears everytime i execute the feature file. What is wrong here?

 解决方案 
This workaround has worked for me. After bundle install, remove the gherkin gem:
gem uninstall gherkin --force
Reinstall the gem (it may take a while):
gem install gherkin --platform ruby -v 2.12.2
Go to the folder of the gem inside your ruby installation directory. Something like this:
{ruby_dir}\lib\ruby\gems\2.1.0\gems\gherkin-2.12.2\lib\gherkin
And replace the lib/gherkin/c_lexer.rb line 7 with:
prefix = ''
This workaround is specified in https://github.com/cucumber/gherkin/issues/273 with the comment by mscharley on Jan 18, 2014.
I have to follow these steps after every bundle install on Windows OS. Tested with Windows 7 and Windows 10.
