Can't install on ruby 2.2.3

Hi, here's the message error I get after gem install :

Building native extensions.  This could take a while...
ERROR:  Error installing rubydeps:

Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers.  Check the mkmf.log file for more details.  You may
need configuration options.

Provided configuration options:

Same problem with 2.3. :cry:

[anicholson]

Me too 😿

Same

Same w/2.1.9. Any takers? It's getting close to a year now. Perhaps another gem is in order?

ruby 2.3.1p112 running on Mint. Same problem. Not happy at all.

Error is:

Looks like conftest relies on MRI header files that don't exist anymore in 2.2+.
