RubyonRails 3 Essential Training

Source code

http://www.lynda.com/Ruby-on-Rails-3-tutorials/essential-training/55960-2.html

While I am following this awesome tutorial, I am typing this code out.

I think the instructor is using a different verion of rails from the one I am using.

So I list my development environment here.

My OS:

Mac OS X 10.8.3 (primary)

Windows 8 (when my mac is not around)

My ruby (on mac):

ruby --version

ruby 1.8.7 (2012-02-08 patchlevel 358) [universal-darwin12.0]

My gem (on mac):

gem --version

2.0.3

My rails (on mac):

rails --version

Rails 3.2.13

Install Rails on Mac with brew

sudo brew install libyaml brew search ruby sudo brew tap homebrew/versions sudo brew install homebrew/versions/ruby193

Install Rails on Linux (CentOS), possible compatibility issues

sudo yum install -y ruby sudo yum install -y ruby-devel ruby-docs ruby-ri ruby-rdoc sudo yum install -y rubygems sudo gem update -v sudo gem install rails -V

Setup centos

yum grouplist | grep Devel Additional Development Desktop Platform Development Development tools Server Platform Development rpm -q centos-release centos-release-6-2.el6.centos.7.x86_64 cat /etc/redhat-release CentOS release 6.2 (Final)

sudo yum groupinstall -y "Additional Development" "Desktop Platform Development" "Development tools" "Server Platform Development"

yum list installed | grep "gcc-c++" yum list installed | grep "zlib" yum list installed | grep "openssl"

Install Ruby from source code

cd /usr/local/src sudo wget http://pyyaml.org/download/libyaml/yaml-0.1.4.tar.gz sudo tar xzvf yaml-0.1.4.tar.gz cd yaml-0.1.4 su ./configure --prefix=/usr/local make make install

sudo wget ftp://ftp.ruby-lang.org/pub/ruby/1.9/ruby-1.9.3-p327.tar.gz sudo tar xzvf ruby-1.9.3-p327.tar.gz cd ruby-1.9.3-p327 su ./configure --prefix=/usr/local --enable-shared --with-opt-dir=/usr/local/lib #make -k > build.log 2>&1 make make install exit

sudo gem update --system -V sudo gem update -V sudo gem install rails -V

for js runtime

sudo gem install therubyracer

if gem cannot install sqlite

sudo yum install sqlite sqlite-devel
