Question

I’ve installed Ruby (1.8.7 via apt-get) and I installed Rails (2.3.2 via rubygems) but when I type ‘rails newapp’, I get this error:

The program 'rails' is currently not installed. You can install it by typing: sudo apt-get install rails
rails: command not found

When I run ‘gem list’ it shows rails and all of it’s dependencies. Any idea what might have gone wrong?

How did you install rubygems? I’ve found problems when using it through the ubuntu repositories in the past. Usually I remove that package and compile and install

sudo apt-get remove rubygems
wget http://rubyforge.org/frs/download.php/70696/rubygems-1.3.7.tgz
tar xzvf rubygems-1.3.7.tgz
cd rubygems-1.3.7/
sudo ruby setup.rb
sudo ln -s /usr/bin/gem1.8 /usr/bin/gem

or you may just have to symbolic link it:

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