我不熟悉Ruby，但无论如何我都试图安装和测试iQvoc（https://github.com/innoq/iqvoc）。 在一些初始问题之后，我设法用heroku安装它。 我现在正在尝试导出一个小的测试词库但我在Ruby上遇到了一些问题。 我用这个命令：
rake --trace iqvoc:export TYPE=ttl NAMESPACE='http://namespace.example.fr/'
我得到了结果：
rake aborted!

我正在使用ubuntu 14.0.6和ruby 2.4
有什么想法吗？
答案 0 :(得分：4)
我使用jazz_hands在Rails 3项目中遇到了类似的错误。这只是在黑暗中拍摄，但试试这个：
bundle update pry-rails pry-remote pry-byebug
然后查看错误是否已修复。
