View Full Version : [SOLVED] Ruby on Rails - strange bug?

June 11th, 2010, 02:47 PM
I want to progress as web developer and want learn Ruby on Rails. But got a strange bug after I've installed this enviroment.

First I've installed 'ruby' with a little help from terminal:

sudo apt-get install ruby

This package also installed 'libruby1.8' and 'ruby1.8'. Afterwards I installed 'irb' and 'rdoc'. Everything went fine.

Then I went to http://rubyforge.org (http://rubyforge.org/frs/?group_id=126) to download the lastest rubygems. The last version available is '1.3.7' which is newer than 'rubygems' package in the repos.
I've unpacked the .tgz and installed with:

sudo ruby setup.rb
Terminal said it was installed without a problem.
But when I want to check the 'rubygems' version with:

gem -v
The terminal says:

"Gem" could be found in the following packages:
* rubygems1.8
* rubygems1.9.1
Try sudo apt-get install <choosen_package>

But I've installed it, yes? Should I install 'rails' with what I've got? Or maybe add the packages from repos and install it then. Will it collide with 'gems' that I installed from source?
I want to make my root filesystem clean as possible.

Thanks in advance.

PS. I'm using Ubuntu 10.04 Lucid Lynx 64bit.

i tried to compile gems from source, it somehow gets confused.

apt-get [install rubygems

i suggest checkin this out:

Solved, thanks for the tip. But I didn't have to install ruby gems from repos, only to make link. After installing it from downloaded sources I typed in terminal:

sudo ln -s /usr/bin/gem1.8 /usr/bin/gem

And it worked.
