Ruby 1.9.3 on Ubuntu 11.10

As mentioned previously, getting the latest version of Ruby on Ubuntu 11.10 is super easy. I hit a snag when 1.9.3 came out, though

$ rvm install 1.9.3
Installing Ruby from source to: 
  /usr/share/ruby-rvm/rubies/ruby-1.9.3,
  this may take a while depending on your cpu(s)...

ruby-1.9.3 - #fetching 
ruby-1.9.3 - #downloading ruby-1.9.3-, this may take a while
  depending on your connection...

curl: (78) RETR response: 550
ERROR: The requested url does not exist:
  'ftp://ftp.ruby-lang.org/pub/ruby/1.9/ruby-1.9.3-.tar.bz2'
...

That tarball is actually supposed to have a p0 on it, but rvm doesn't seem to think so. So let's fetch it ourselves and put it where rvm will find it.

curl -o /usr/share/ruby-rvm/archives/ruby-1.9.3-.tar.bz2 \
  http://ftp.ruby-lang.org/pub/ruby/1.9/ruby-1.9.3-p0.tar.bz2

Now rvm will do the install for us

$ rvm install 1.9.3
Installing Ruby from source to:
  /usr/share/ruby-rvm/rubies/ruby-1.9.3,
  this may take a while depending on your cpu(s)...

ruby-1.9.3 - #fetching 
ruby-1.9.3 - #extracting ruby-1.9.3- to
  /usr/share/ruby-rvm/src/ruby-1.9.3
ruby-1.9.3 - #extracted to /usr/share/ruby-rvm/src/ruby-1.9.3
ruby-1.9.3 - #configuring 

That way we can still manage it with rvm

$ rvm use 1.9.3
Using /usr/share/ruby-rvm/gems/ruby-1.9.3
$ rvm list

rvm rubies

=> ruby-1.9.3 [ x86_64 ]
   ruby-1.9.2-p180 [ x86_64 ]

Note that ruby-1.9.3 is not called ruby-1.9.3-p0 as it probably should be. Ruby itself still has this information

$ ruby -v
ruby 1.9.3p0 (2011-10-30 revision 33570) [x86_64-linux]

but rvm has lost it. Maybe we were supposed to convince rvm to do the install with a -p0, rather than accommodating its need for a - with nothing after it?

Update: (16 Feb 2012) Ruby 1.9.3-p125 has been released. It seems to be packaged properly, so everyone should be able to just run

$ rvm install ruby-1.9.3-p125

and have the updated Ruby install in one go. And new folks should just get the new one without any of the problems described above.

Sure thing! Have fun with Ruby 1.9.3!

[SeverineDarlot]

Thank you, it was useful for me

it would worked better if you use sudo rvm install ruby-1.9.3-p125 on ubuntu 11.10 it would work than installing it manually.

Thanks for the post.
I installed ruby-1.9.3-p125.
"rvm use 1.9.3" not working for me.
I need to provide patch with version to switch
means "rvm use 1.9.3-p125" only working.
Why is it so?

[oylenshpeegul]

Huh. I don't know. I have to say "rvm use 1.9.3-p125" too, but I assumed that was because I had more than one (when I say "rvm use 1.9.3", I get 1.9.3-p0).

You rock, good work!

[InsideOutCloud]

Thanks, this worked perfectly!
