Also, because Debian version is (of course) outdated and besides that i ran into a lot of problems while i was trying to install it using the packages... Yeah, gotta love Debian <stable>. Errors like:
- File not found: lib.
- Execjs: Could not find a JavaScript runtime
- And so on...
First some packages that you probably already have if you are a developer:
apt-get install curl git-core
Now because RVM downloads and compiles a LOT of the stuff we are installing you'll need:
apt-get install build-essential openssl libreadline6 libreadline6-dev zlib1g zlib1g-dev libssl-dev libyaml-dev libsqlite3-0 libsqlite3-dev sqlite3 libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev automake libtool bison
(Again, if you are a developer you might already have some of em installed)
And this one if you plan to use Mysql on your project:
apt-get install libmysqlclient-dev
Here, make sure you don't have any Ruby packages installed and begin installing RVM (and from now on don't run anything as root):
bash < <(curl -sk https://rvm.beginrescueend.com/install/rvm)
echo '[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" # Load RVM function' >> ~/.bash_profile
Now if you are a Gnome user make sure to check this option on your Terminal profile perferences (don't ask me why, just do it™ ):
To continue restart your Terminal, then:
// Checks if rvm is installed correctly (it MUST return 'rvm is a function')At this point if everything went OK you are good to go, still I recommend ya to run a simple app to make sure:
$> type rvm | head -1
// Install Ruby and make sure it works
$> rvm install 1.9.2
$> rvm use 1.9.2
$> ruby -v
// Create a new gemset and install Rails
$> rvm gemset create rails305
$> gem install rails -v 3.0.5
// SQlite database extension
$> gem install sqlite3
// MySQl database extension
$> gem install mysql2
