Hello, I'm trying to install the rails on ubuntu 11.10, but when I put the command
felipe@Felipe:~/Downloads/rubygems-1.8.15$ sudo gem install rails --no-r1 --no-rdoc ERROR: Loading command: install (LoadError) no such file to load -- zlib ERROR: While executing gem ... (NameError) uninitialized constant Gem::Commands::InstallCommand felipe@Felipe:~/Downloads/rubygems-1.8.15$

Thanks
Hello, I'm trying to install the rails on ubuntu 11.10, but when I put the command
felipe@Felipe:~/Downloads/rubygems-1.8.15$ sudo gem install rails
The best way to install rails is to use rvm. See http://beginrescueend.com/

Have you installed: apt-get install zlib1g zlib1g-dev
Also - in general, it is not a good idea to install gems using sudo.
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.
you face is probably that you miss a number -dev libraries.
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).

CavalryJim, what is the best way to install ?
I'm following the tutorial, but when I try put the commando 'rvm install 1.8.7' shows
felipe@Felipe:~$ rvm install 1.8.7 bash: /usr/bin/rvm: File or folder not found felipe@Felipe:~$
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'
felipe@Felipe:~$ gem install rails ERROR: Loading command: install (LoadError) no such file to load -- zlib ERROR: While executing gem ... (NameError) uninitialized constant Gem::Commands::InstallCommand felipe@Felipe:~$
some lib are missing, but I put the command
sudo apt-get install zlib1g zlib1g-dev
and was all updated
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):
peterv@ASUS:~$ ruby -v
ruby 1.9.3p0 (2011-10-30 revision 33570) [i686-linux]
peterv@ASUS:~$ which ruby
/home/peterv/.rvm/rubies/ruby-1.9.3-p0/bin/ruby
peterv@ASUS:~$ gem -v
1.8.10
peterv@ASUS:~$ which gem
/home/peterv/.rvm/rubies/ruby-1.9.3-p0/bin/gem
peterv@ASUS:~$ echo $PATH
/home/peterv/.rvm/gems/ruby-1.9.3-p0/bin:/home/peterv/.rvm/gems/ruby-1.9.3-p0@global/bin:/home/peterv/.rvm/rubies/ruby-1.9.3-p0/bin:/home/peterv/.rvm/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games
Falling back (what I normally never do anymore) to system ruby:
peterv@ASUS:~$ rvm use system
Now using system ruby.
peterv@ASUS:~$ ruby -v
ruby 1.8.7 (2010-01-10 patchlevel 249) [i486-linux]
peterv@ASUS:~$ which ruby
/usr/bin/ruby
peterv@ASUS:~$ gem -v
1.3.7
peterv@ASUS:~$ which gem
/usr/bin/gem
peterv@ASUS:~$ echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/home/peterv/.rvm/bin
HTH,

Ok, but, when I try with ‘gem install rails’
felipe@Felipe:~$ gem install rails ERROR: Loading command: install (LoadError)
no such file to load -- zlibERROR: While executing gem … (NameError)
uninitialized constant Gem::Commands::InstallCommand
felipe@Felipe:~$
some lib are missing, but I put the command
sudo apt-get install zlib1g zlib1g-dev
and was all updated
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
peterv@ASUS:~$ rvm get stable

Ok, I try, but, look what happen when I put rvm get stable
felipe@Felipe:~$ rvm get stable felipe@Felipe:~$
nothing...
I'm brazilian, so, the language is portuguese, but I guess is easy to know the error messages.

I'm using Ubuntu 11.10, I was following, before your steps, this tutorial: http://blog.sudobits.com/2011/10/27/how-to-install-ruby-on-rails-in-ubuntu-11-10/
Thank for all the people that help me, I see another tutorial, and I was having a huge mistake, I wasn't restart the terminal, that was the problem...
Thank's again...
