Googling for
rvm no such file to load zlib
finds links that will probably help.

I got the same problem, i think it’s something with rubygems that is
not compiled correctly but so far i can’t find the fix.

Just now i got soultion.

First remove ruby installed versions .

And try to run these commands :

sudo apt-get install build-essential bison openssl libreadline5
libreadline-dev curl git-core zlib1g zlib1g-dev libssl-dev vim
libsqlite3-0
libsqlite3-dev sqlite3 libreadline-dev libxml2-dev git-core subversion
autoconf

sudo bash -s stable < <(curl -s
https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer
)

rvm -v

rvm ls

gem update

Thanks,
Sai

Wow I never heard that errors before. i think the easy way to resolve
that
is remove your old gem, or check your rvm n ruby installed correctly or
not?
that’s was my last option when i found errors n cannot resolve it.
