Question

我有一个小的Rails 4.0.0 / Ruby 2.0.0-p247应用程序，我想写一些测试。我跑的时候

rake cucumber:all

我收到以下错误：

我运行捆绑安装，捆绑更新，宝石清理等无济于事。这个相同的Rails应用程序在另一台机器（Mac OS X 10.8.4）上运行良好，但我的（Mac OS X 10.8.2）不起作用。有什么想法吗？

Answer 1

我有完全相同的错误。原因在于：

https://github.com/intridea/multi_json/issues/131

由于他们有错误修复，所以您需要做的就是将multi_json更新为1.7.9

- 已编辑请不要更改Gemfile.lock，检查注释以获取详细信息

Answer 2

我认为问题的根源不是来自JSON :: Parser。 'ruby_noexec_wrapper'错误可能表明存在RVM问题。

尝试

which cucumber

它应该别名为bundled_cucumber

还尝试更新RVM

rvm get stable

和/或制作新的宝石

rvm gemset empty

黄瓜耙任务失败，归咎于JSON解析器
