linux - Error in ruby: cannot load such file -- zlib -

when seek install rails in ubuntu 12.10 error:

$ gem install rails error: loading command: install (loaderror) cannot load such file -- zlib error: while executing gem ... (nameerror) uninitialized constant gem::commands::installcommand

so removed rvm:

rvm implode sudo rm -rf ~/.rvm

removed script calls in .bashrc , .bash_profile

and checked if they're removed:

env | grep rvm #no output, rvm removed ruby -v #the programme 'ruby' can found in next packages: blabla

i have these via sudo apt-get install:

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

then proceed install scratch

curl -l https://get.rvm.io | bash -s stable --ruby --auto-dotfiles

then run line , restarted terminal regard message:

* start using rvm need run `source /home/adige/.rvm/scripts/rvm` in open shell windows, in rare cases need reopen shell windows.

then rvm pkg install readline completed error:

... error running 'autoreconf -is --force', please read /home/adige/.rvm/log/readline/autoreconf.log ... please note it's required reinstall rubies: rvm reinstall --force

i think it's installed anyway, right? before reinstall rubies, installed zlib of course:

# w/out verify, gives checksum error rvm pkg install zlib --verify-downloads 1

then run rvm reinstall --force , completed error again:

... install of ruby-1.9.3-p374 - #complete making gemset ruby-1.9.3-p374 pristine. error running '' under , please read /home/adige/.rvm/log/ruby-1.9.3-p374/gemset.pristine.log making gemset ruby-1.9.3-p374@global pristine.

gemset.pristine.log

then reinstall ruby zlib support:

rvm reinstall 1.9.3-p374 --with-zlib-dir=$rvm_path/usr

which returned same error , same log completed anyway.

finally tried install rails gem 1 time again cannot load such file -- zlib !

here rvm info

what doing wrong?

you should not install readline / zlib on ubuntu, follow steps:

rvm head rvm pkg remove rvm requirements run forcefulness rvm reinstall 1.9.3-p374

make sure include output of installation process if fails, include mentioned log files
