I am getting the following error when I try to install rails on lucid  
lynx :-

mark@mark-laptop:~/code/ruby$ sudo gem install rails  
ERROR: Error installing rails:  
i18n requires RubyGems version \>= 1.3.6

I have installed RubyGems1.9.1, but it seems that “gem” is still at  
version 1.3.5 :-

mark@mark-laptop:~/code/ruby$ /usr/bin/gem1.9.1 -v  
1.3.5

I have the following version of Ruby :-

mark@mark-laptop:~/code/ruby$ ruby -v  
ruby 1.8.7 (2010-01-10 patchlevel 249) [i486-linux]

Any idea what I am doing wrong?

Mark.

Hi Mark,

Apparently you can only update ruby gems from the repositories. What I  
have done was install it from source. Just grab the source and install  
it. It will overwrite the existing one.

I don’t know if anyone else has another solution, but that is the one I  
found.

Hope that helps.

Regards,

Fidel.

Additionally, Mark, don’t use ruby 1.9.1 with rails: it’s buggy.and it’s  
not  
recommended, as mentioned on RoR home page. Consider compiling ruby from  
source, either version 1.8.7 or 1.9.2. Follow the step by step  
instructions  
from Ruby official site if in doubt. Install RubyGems manually  
afterwards by  
running the install script form their official page:  
[http://rubygems.org/pages/download](http://rubygems.org/pages/download)  
[http://rubygems.org/pages/download](http://rubygems.org/pages/download)As a third step, just install rails  
as  
a gem. I’,m also using Ubuntu as a development environment and I  
recommend  
you to keep up-to-date on your tools by following this install path. The  
repositories are lagging behind.
