How to Install Ruby on FreeBSD

Ruby Logo

The object-oriented programming language is available as a port on FreeBSD. Ruby combines syntax inspired by Perl with Smalltalk-like features and is influenced by Eiffel and Lisp as well. With Ruby you can make use of multiple programming paradigms, including functional, object oriented, imperative and reflective. The automatic memory management and a dynamic type system are one of the main key factors to use Ruby.

Root access is required to edit the following files and to execute commands. Log in as root (su) or simply prepend sudo to all commands that require root privileges.

Install Ruby 1.8

With the following commands you will install Ruby 1.8 from the ports directory:

cd /usr/ports/lang/ruby18/
make install clean; rehash

At this point Ruby 1.8 is installed. If you want to use a newer version, RVM can help you. This tutorial also explains how to install the RVM manager.

Install Curl

Install Curl for later use.

cd /usr/ports/ftp/curl
make install clean; rehash

Install Bash

Bash is needed to use Ruby properly.

cd /usr/ports/shells/bash
make install clean; rehash

Install Git

The following commands will install Git:

cd /usr/ports/devel/git
make install clean; rehash

Create a user

Add a new user for your Ruby environment.

adduser

Username: rvm
Full name: Ruby Version Manager
Uid (Leave empty for default): 
Login group [rvm]: 
Login group is rvm. Invite rvm into other groups? []: 
Login class [default]: 
Shell (sh csh tcsh bash rbash nologin) [sh]: bash
Home directory [/home/rvm]: 
Home directory permissions (Leave empty for default): 
Use password-based authentication? [yes]: no
Lock out the account after creation? [no]: no
Username   : rvm
Password   : 
Full Name  : Ruby Version Manager
Uid        : 1001
Class      : 
Groups     : rvm 
Home       : /home/rvm
Home Mode  : 
Shell      : /usr/local/bin/bash
Locked     : no
OK? (yes/no): yes
adduser: INFO: Successfully added (rvm) to the user database.

Log in as user

Log in with the newly created user (rvm) to install Ruby in this environment.

su rvm

Install RVM

The following command will install the RVM manager:

bash -s stable < <(curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer )

# HELP: http://webchat.freenode.net/?channels=rvm (#rvm on irc.freenode.net)
# Screencast: http://screencasts.org/episodes/how-to-use-rvm

# In case of any issues read output of 'rvm requirements' and/or 'rvm notes'

Installation of RVM in /home/rvm/.rvm/ is almost complete:

  * To start using RVM you need to run `source /home/rvm/.bashrc`
    in all your open shell windows, in rare cases you need to reopen all shell windows.

# rvm,
#
#   Thank you for using RVM!
#   I sincerely hope that RVM helps to make your life easier and more enjoyable!!!

Load RVM at login

Type these commands into the console to start RVM at login:

echo '[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" # Load RVM function' >> ~/.bash_profile
echo '[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" # Load RVM function' >> ~/.bashrc

Reload Bash profile

Reload your Bash profile so that the previous changes can take effect.

source ~/.bash_profile

Check that all is OK

Receiving an other response than rvm is a function means that RVM is not loaded.

type rvm | head -1

rvm is a function

List available Ruby versions

Now, you can list the available Ruby versions with the following command:

rvm list known

Install Ruby

Install your favorite Ruby version.

rvm install 1.9.3-head

Set the default Ruby version

Set the just installed Ruby version as default.

rvm use 1.9.3-head --default

Check your installed Ruby version

Check your Ruby version with this command:

ruby -v

    Hello,

    My installation failed while installing rvm requirements, have you any tips?

    $ type rvm | head -1
    rvm is a function

    $ rvm install 1.9.3-head
    Installing requirements for freebsd, might require sudo password.
    (do anything until I ctrl-c)

    $ rvm requirements –debug
    rvm_autolibs_flag=enable
    Installing requirements for freebsd, might require sudo password.
    requirements code for freebsd loaded
    (do anything until I ctrl-c)

    Thanks!
