Ruby: cannot load such file -- iconv (LoadError)

I installed ruby and I have been trying to use it with metasploit, but everytime I launch msfconsole or msfcli
I get this error:

I think it's a problem regarding ruby rather than metasploit.
Maybe there is something wrong with the package (2.0.0_p0-1)

Re: Ruby: cannot load such file -- iconv (LoadError)

iconv has been deprecated for a while. It is replaced by (builtin) String#encode

* Downgrade to an older ruby; or
* Ask metasploit to fix their code.

Thanks. I downgraded to a previous version of ruby and now everything works fine.
