Install Ruby on Rails on Windows & Linux

First we will start with installing Ruby on Rails on a windows system, we would be requiring couple of software that needs to be downloaded from the internet.

  1. Rails Installer ( download )
  2. Node Js ( download for 32 bit | 64 bit )
  3. Sublime text for code editor ( download for 32 bit | 64 bit )
  4. Sqlite3 DB Browser ( download for 32 bit | 64 bit )

Rails Installer consists of the following : ruby 2 , rails 4 , bundler , git , sqlite database & devkit.

Incase your computer has an admin user, then login as admin and install, else install the software as a regular user.  Restart the computer once all 3 software are installed.

After restart follow the following steps :

STEP 1 – Open command prompt and goto c:/Sites
STEP 2 – rails new my_ap

NOTE – While working with windows majority of people might get a SSL Error, you will need to follow the instructions mentioned below to have it fixed.

Solution for Windows SSL Error (FIXED)

SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed
In Windows Machine is
Actually the best way I found to solve this in windows for Ruby itself, not just one gem, is to do the following:

Steps:

    *   Download  http://curl.haxx.se/ca/cacert.pem  into
C:\railsinstaller\cacert.pem
    *   Make sure you save it as a .pem file, rather than a text file.
    *   Go to your Computer -> Advanced Settings -> Environment
Variables
    *   Create a new System Variable:
Variable: SSL_CERT_FILE
Value: C:\RailsInstaller\cacert.pem
    *   Close all your command prompts, including your Rails server
command prompt etc.
    *   Start a new ruby irb prompt, and try the following:
    *   $irb>require ‘open-uri’

After following these steps, it will take a few minutes for all the libraries to be downloaded and installed on your computer. These steps (1-5) needs to be followed every time you start a new project.

Installing Ruby on Rails on Ubuntu 16x

The first step is to install some dependencies for Ruby.

STEP 1 - sudo apt-get update

STEP 2 - sudo apt-get install git-core curl zlib1g-dev build-essential libssl-dev libreadline-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt1-dev libcurl4-openssl-dev python-software-properties libffi-dev

Installing with rbenv is a simple two step process. First you install rbenv, and then ruby-build:

cd
STEP 3 - git clone https://github.com/rbenv/rbenv.git ~/.rbenv
STEP 4 - echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc
STEP 5 - echo 'eval "$(rbenv init -)"' >> ~/.bashrc
STEP 6 - exec $SHELL
STEP 7 - git clone https://github.com/rbenv/ruby-build.git ~/.rbenv/plugins/ruby-build

STEP 8 - echo 'export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH"' >> ~/.bashrc

STEP 9 - exec $SHELL rbenv install 2.3.1 rbenv global 2.3.1 ruby -v

STEP 9 - gem install bundler (note - run rbenv rehash after installing bundler)

Configuring Git

STEP 1 - git config --global color.ui true

STEP 2 - git config --global user.name "YOUR NAME"

STEP 3 - git config --global user.email "YOUR@EMAIL.com"

STEP 4 - ssh-keygen -t rsa -b 4096 -C "YOUR@EMAIL.com"

Installing Rails

To install NodeJS, we’re going to add it using the official repository:

curl -sL https://deb.nodesource.com/setup_4.x | sudo -E bash -
sudo apt-get install -y nodejs

And now, without further adieu:

gem install rails -v 4.2.6

If you’re using rbenv, you’ll need to run the following command to make the rails executable available:

rbenv rehash

Now that you’ve installed Rails, you can run the rails -v command to make sure you have everything installed correctly:

rails -v
# Rails 4.2.6

If you get a different result for some reason, it means your environment may not be setup properly.

Linux installation steps have been taken from Go Rails Website, if you are using other versions of Linux, you will find more information in this link. Check it out 🙂

Install Sublime-Text-3 via package manager:

sudo add-apt-repository ppa:webupd8team/sublime-text-3
sudo apt-get update
sudo apt-get install sublime-text-installer

 

ERROR (FIXED) :

When you try to check the rails version in Command Prompt, you might get this following error ,

The system cannot find the path specified.

SOLUTION :

  1. Open the rails.bat file (By default in : C:\RailsInstaller\Ruby2.2.0\bin\rails.bat)
  2. Find the line of code showing a path like this, 
     @"C:\Users\emachnic\GitRepos\railsinstaller-windows\stage\Ruby2.2.0\bin\ruby.exe"
  3. Replace the line with 
     @"%~dp0ruby.exe"

    and save.

  4. After changing, your file will look like this, 
    @ECHO OFF
IF NOT "%~f0" == "~f0" GOTO :WinNT
@"%~dp0ruby.exe"
"C:/Users/emachnic/GitRepos/railsinstaller-windows/stage/Ruby2.2.0/bin/rails" %1 %2 %3 %4 %5 %6 %7 %8 %9
GOTO :EOF
:WinNT
@"%~dp0ruby.exe" "%~dpn0" %*
  5. Repeat Steps 2 to 4 for bundle.bat file in the same folder.
  6. Run rails -v to check the version of Rails installed.
  7. And, that’s it.. Happy coding!
