When i try to install rails in Ubuntu 12.10 i get this 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 i completely removed rvm:
rvm implode
sudo rm -rf ~/.rvm
removed the script calls in my .bashrc and
.bash_profile
and checked if they’re really removed:
env | grep rvm #no output, so rvm is removed
ruby -v #The program 'ruby' can be found in the following packages:
blabla
I already 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 to install from scratch
curl -L https://get.rvm.io | bash -s stable --ruby
--auto-dotfiles
then run that line and restarted terminal regard to this message:
* To start using RVM you need to run `source
/home/adige/.rvm/scripts/rvm`
in all your open shell windows, in rare cases you need to reopen
all shell windows.
Then
rvm pkg install readline
but completed with error:
[CODE]…
Error running ‘autoreconf -is --force’, please read
/home/adige/.rvm/log/readline/autoreconf.log
…
Please note that it’s required to reinstall all rubies:
rvm reinstall all --force[/CODE]
I think it’s installed anyway, right? Before reinstall all rubies, i
installed zlib of course:
# w/out verify, it gives checksum error
rvm pkg install zlib --verify-downloads 1
Then run
rvm reinstall all --force
and completed with error again:
...

Error running '' under ,
please read /home/adige/.rvm/log/ruby-1.9.3-p374/gemset.pristine.log

gemset.pristine.log: [2013-02-06 14:19:04] rvm gemset pristine # under ruby-1.9.3-p374Restoring gem - Pastebin.com
Then reinstall ruby with zlib support:
rvm reinstall 1.9.3-p374 --with-zlib-dir=$rvm_path/usr
which returned same error and same log([2013-02-06 14:19:04] rvm gemset pristine # under ruby-1.9.3-p374Restoring gem - Pastebin.com) but
completed anyway.
Finally i tried to install rails gem again but
cannot load such file -- zlib !
Here is the rvm info: ruby-1.9.3-p374: system: uname: "Linux adige-LG 3.5.0-23-generic - Pastebin.com
What am i doing wrong?
