Setup Ruby with Ubuntu

setup Ruby on Ubuntu 12.04 LTS with rbenv - I installed Ubuntu to my old laptop (Windows 7) with - wubi. And I did

open terminal = ctrl + alt + T

(and then connect to Wi-Fi )

install git

$ sudo apt-get update
$ sudo apt-get install git

https://github.com/sstephenson/rbenv#installation

https://github.com/sstephenson/ruby-build#readme

follow direction and install rbenv + ruby-build

$ git clone https://github.com/sstephenson/rbenv.git ~/.rbenv
$ echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc
$ echo 'eval "$(rbenv init -)"' >> ~/.bashrc
$ exec $SHELL 
$ type rbenv
"rbenv is a function"
$ git clone https://github.com/sstephenson/ruby-build.git ~/.rbenv/plugins/ruby-build

install ruby - stable versions

$ rbenv install 1.9.3-p545
$ rbenv install 2.0.0-p451
$ rbenv install 2.1.1
$ rbenv versions
$ rbenv global 2.0.0-p451
$ rbenv version
$ ruby -v
$ rbenv rehash

However it said “The Ruby openssl extension was not compiled. Missing the OpenSSL lib?” So I did

( found it by search ) this first and install Ruby.

$ sudo apt-get -y install build-essential zlib1g-dev libreadline-dev libssl-dev libcurl4-openssl-dev libsqlite3-dev 

$ rbenv install 2.0.0-p451

And then…

Rails install was successful to me on 2.0.0.

install sqlite3

$ gem install sqlite3

bundler

$ gem install bundler

http://rubyonrails.org/download/

rails

$ gem install rails --no-ri --no-rdoc

( forget --no-ri --no-rdoc part, and wait extra long time )

$ rails new testapp
$ cd testapp
$ rails server

http://localhost:3000/

Tried to open on localhost. This time it said “Could not find a JavaScript runtime” So I did

https://github.com/joyent/node/wiki/Installing-Node.js-via-package-manager#ubuntu-mint-elementary-os

install node.js

$ sudo apt-get install nodejs
$ node -v
v0.10.26

$ exec $SHELL
$ rails -v
