The best way to install rails is to use rvm. See

Have you installed:
apt-get install zlib1g zlib1g-dev
Also - in general, it is not a good idea to install gems using sudo.

CavalryJim, what is the best way to install ?

https://rvm.beginrescueend.com/
E.g. for Ubuntu 11.10, I wrote a detailed log of doing it from scratch
(and there are many others if you Google):
Note that you will NOT need to do “sudo” with rvm, It is a local install
that you could alway wipe out and start over etc. if you are
experimenting …
(you could even make a separate “ror” user and do rvm there,
just to practice without risk.
Probably
$ sudo apt-get install zlib1g zlib1g-dev
will get you out of this one and then you will probably hit the next
error
…
(I recently installed on a different Ubuntu 11.10 without rvm, it was a
lot
harder and the write-up is here:
http://rails.vandenabeele.com/blog/2012/01/15/installing-ruby-rails-passenger-on-ubuntu-11-dot-10/
Not advised unless you are more experienced).
HTH,

As Colin stated, a best practice for installing ruby is rvm.
For installing rails, use ‘gem install rails’
For all other gems, add the gem to your projects gemfile and run
‘bundle install’.
Ok, but, when I try with ‘gem install rails’
[email protected]:~$ gem install rails
ERROR: Loading command: install (LoadError)
no such file to load – zlib
ERROR: While executing gem … (NameError)
uninitialized constant Gem::Commands::InstallCommand
[email protected]:~$
some lib are missing, but I put the command
sudo apt-get install zlib1g zlib1g-dev
and was all updated
I’m following the tutorial, but when I try put the commando ‘rvm install
1.8.7’ shows
[email protected]:~$ rvm install 1.8.7
bash: /usr/bin/rvm: File or folder not found
[email protected]:~$

From which source did you install your ruby and rubygems?
Where are they installed?
Could you run these commands and show the output please.
$ ruby -v
$ which ruby # if it is a symlink, follow it also
$ gem -v
$ which gem # if it is a symlink follow it also
$ echo $PATH
And again … even if you have started with manual install
of Ruby etc, you can still go to rvm (and inside rvm you
can use $ rvm system to go back to the system installed
ruby if you need to; I demonstrate that below).
As reference, on my system (rvm on Ubuntu 11.10):
[email protected]:~$ ruby -v
ruby 1.9.3p0 (2011-10-30 revision 33570) [i686-linux]
[email protected]:~$ which ruby
/home/peterv/.rvm/rubies/ruby-1.9.3-p0/bin/ruby
[email protected]:~$ gem -v
1.8.10
[email protected]:~$ which gem
/home/peterv/.rvm/rubies/ruby-1.9.3-p0/bin/gem
[email protected]:~$ echo $PATH

Falling back (what I normally never do anymore) to system ruby:
[email protected]:~$ rvm use system
Now using system ruby.
[email protected]:~$ ruby -v
ruby 1.8.7 (2010-01-10 patchlevel 249) [i486-linux]

I have used Rails Ready in the past, and it made the setup rather easy.

Ah, you actually do have rvm installed …
Did you already install some rubies ?
Anyway, this sequence should work then
