Error while running features2cards

[RoRoche]

Here is my system requirements:

• macOS Sierra, Version 10.12.3
• ruby 2.4.0p0 (2016-12-24 revision 57164) [x86_64-darwin16]
• export PATH=/Users/Romain/.rbenv/versions/2.4.0/bin:$PATH

When running the following command features2cards sum.feature, I get the following stacktrace:

/Users/Romain/.rbenv/versions/2.4.0/lib/ruby/gems/2.4.0/gems/features2cards-0.4.0/lib/features2cards/platform.rb:8:in `<module:Features2Cards>': uninitialized constant Features2Cards::Config (NameError)
Did you mean?  RbConfig

How to get rid of this issue?

Exactly the same error, happening on Linux Mint 16, and Ruby 2.4.
