I am trying to install lorcon2 library on metasploit. I realized both by experience and from what I've read in the forums that lorcon2 library (used by metasploit in wireless attacks) has problems with installations that have multiple ruby versions.
I would like to know how to view all
installed versions of ruby in my box. I am using Linux (Kali).
I noticed that ruby comes preinstalled and after issuing:
ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-linux]
rvm is not installed by default so I did:
\curl -L https://get.rvm.io
| bash -s -- --autolibs=read-fail
but now after issuing:
# No rvm rubies installed yet. Try 'rvm help install'.
My ultimate goal is find all 1.8 versions of ruby and gems, purge them so I keep 1.9 version as the only one.
I am not familiar at all with the ruby language or the ruby terminology so I don't understand what the role of gems, or rvm is.
Thanks in advance.
