Install rails 3 beta4 with ruby 1.8.7 on ubuntu

21 July, 2010

Type ruby –version you should have that if you didn’t update ruby before :


jdasilva@jdasilva:~$ ruby --version
ruby 1.8.7 (2010-01-10 patchlevel 249) [i486-linux]

This version is not completely compatible with rails 3
(according to http://guides.rails.info/3_0_release_notes.html)

So first thing, we will install the ruby 1.8.7 enterprise edition that you can find here :
http://www.rubyenterpriseedition.com/download.html

Now if you should have this (you may have to open a new terminal):


jdasilva@jdasilva:~$ ruby --version
ruby 1.8.7 (2010-04-19 patchlevel 253) [i686-linux], MBARI 0x8770, Ruby Enterprise Edition 2010.02

Ruby is ready, let’s install rails 3 now


jdasilva@jdasilva:~$ sudo gem install rails --pre
[sudo] password for jdasilva:
