Hi - I installed ruby for something... The instructions said to also do the comand:
gem install reel ERROR: Error installing reel: timers requires Ruby version >= 2.2.1. [root@devgeis ~]# ruby --version ruby 2.0.0p648 (2015-12-16) [x86_64-linux]
Not sure what to do. Wait for Centos 8? Thoughts? Thanks,
Jerry

Install CentOS SCLo RH repository: yum install centos-release-scl-rh
Install rh-ruby22-ruby rpm package: yum install rh-ruby22-ruby
currently 2.2.9, I think.
Thanks John for the info... I did that and now I'm missing a file. I tried to ask yum what package I need - but It did not know.

most typically .h files are included in a -dev package, but I dunno about this one. googling rh-ruby22, I find, oops, its EOL, and replaced with rh-ruby23
https://www.softwarecollections.org/en/scls/rhscl/rh-ruby23/
btw, with the SCL stuff, note the "scl enable rh-ruby23 bash" command, that spawns you a shell with that packages directories in the path... that might make this work. see that page for more details, including a gem run.
