我刚用rvm为rails开发设置了一个 Linux Mint盒子.我继续生成了一个Rails 5应用程序,设置了mysql连接,添加了 cucumber-rails gem,然后尝试运行：

rake cucumber

出于某种原因,我遇到了：

/usr/bin/ruby2.3 -S bundle exec cucumber --profile default

据我所知,这是一个相当简单的香草装置,所以我无法理解我为获得这些警告所做的工作.我在某种程度上有相互矛盾的宝石吗？如果是这样,我该如何解决？

解决方法

我设法通过以下方式摆脱JSON警告：

bundle clean --force
bundle
