But I get the error where net-ssh needs Ruby version >= 2.2.6
gem install oxidized
Fetching: asetus-0.3.0.gem (100%)
Successfully installed asetus-0.3.0
Fetching: net-ssh-5.2.0.gem (100%)
ERROR: Error installing oxidized:
net-ssh requires Ruby version >= 2.2.6.
Can someone explain how how I check the version installed and how I upgrade it?
