I'm trying to install ruby on rails from scratch on Ubuntu 12.10. Getting help from this post:
echo "[[ -s '${HOME}/.rvm/scripts/rvm' ]] && source '${HOME}/.rvm/scripts/rvm'" >> ~/.bashrc
echo "[[ -s '${HOME}/.rvm/scripts/rvm' ]] && source '${HOME}/.rvm/scripts/rvm'" >> ~/.zshrc
curl -L https://get.rvm.io | bash -s stable
# Then run this in order to make rvm work:
source /home/adige/.rvm/scripts/rvm
# And installed zlib, before ruby:
rvm pkg install zlib
# Last step, installed ruby:
rvm install 1.9.3 --with-zlib-dir=/home/adige/.rvm/usr
But the problem is when i try to install gems i get this error:
adige@adige-LG:~$ gem install rails
ERROR: Loading command: install (LoadError)
cannot load such file -- zlib
ERROR: While executing gem ... (NameError)
uninitialized constant Gem::Commands::InstallCommand
I already have these:
curl zlib1g-dev zlib1g libssl-dev build-essential openssl libreadline6 libreadline6-dev curl git-core libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev automake libtool bison subversion pkg-config
So what may be the problem?

In case of anyone's interested, i removed
RVM
and compiledRuby
from source code, as the official page recommends, then installed rails gem by:Using sudo is essential.
