Al finalzar la instalación un mensaje nos advierte:
* To switch between available Ruby profiles, execute as root:
*
eselect ruby set ruby(18|19|...)
Procedemos:
# eselect ruby list
Available Ruby profiles:
[1] ruby18 (with Rubygems) *
# eselect ruby set ruby18
Successfully switched to profile:
ruby18
Averiguar versión instalada:
# gem -v
1.3.7
Instalar rails a través de Rubygem:
# gem18 install rails --include-dependencies
INFO: `gem install -y` is now default and will be removed
INFO: use --ignore-dependencies to install only the gems you list
Building native extensions. This could take a while...
Depending on your version of ruby, you may need to install ruby rdoc/ri data:
<= 1.8.6 : unsupported
= 1.8.7 : gem install rdoc-data; rdoc-data --install
= 1.9.1 : gem install rdoc-data; rdoc-data --install
>= 1.9.2 : nothing to do! Yay!
...
En un futuro para actualizar Rails solo tendremos que teclear:
# gem update rails --include-dependencies
# emerge -av sqlite3-ruby
