Tested on Yosemite. Should work on El Cap. Message me if it doesn't.
- You are tired of using vagrant
- You want to run guard
- You want use Sublime plugins (like RSpec or Guard plugins)
- You want your code to run faster in development
Brew aka Homebrew is a package management system for Mac OSX. You can think of it as a command line version of the App Store.
Open up the Mac Terminal and run this command to install brew on your mac:
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
After brew is done installing run
brew update
GNU File, Shell, and Text utilities needed to compile gems.
brew install coreutils
Open a terminal window. Run this command to download an install rvm and the latest version of ruby.
\curl -sSL https://get.rvm.io | bash -s stable --ruby
In the latest version of ruby you might see this error: "Empty path passed to certificates update, functions stack". There is a bug in rvm. Run rvm reinstall 2.5.0 --disable-binary.
Close the current terminal window and open a new one.
rvm list # shows you all the versions of ruby installed on your computer
rvm -h # shows you the help menu with all the commands you can run
# Install ruby version 2.5.0
rvm install 2.5.0
# this will take a while... rvm is downloading and installing ruby
# Tell rvm to use 2.5.0 as the default version of ruby
rvm --default use 2.5.0
# Check that you are using the latest version of ruby
ruby -v
# Should show ruby 2.5.0
Install rails on your system so you can create new rails projects.
gem install rails
And now we can verify Rails is installed:
rails -v
# Rails 4.1.1
Install the server
brew install postgresql
Initialize the database
initdb /usr/local/var/postgres -E utf8
Get postgres to start automatically when your computer starts.
First, figure out which version of postgres was installed by brew.
cd /usr/local/Cellar/postgresql/
ls
# There should be a folder in here with the version number
Then, run the code below, replacing 9.2.1 with your version of postgresql.
mkdir -p ~/Library/LaunchAgents
cp /usr/local/Cellar/postgresql/9.2.1/homebrew.mxcl.postgresql.plist ~/Library/LaunchAgents/
launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist

gem install pg
Note: This might fail. If it does, ask a TA or add a comment to this gist.
The nokogiri gem needs these. See here for details: http://jasdeep.ca/2013/10/installing-nokogiri-fails-os-x-mavericks/
xcode-select --install
Follow these instructions: http://stackoverflow.com/questions/23260748/manual-install-of-xcode-command-line-tools-not-working
- Open XCode
- Click on Xcode > Open Developer Tools > More Developers Tools This will take you to the Downloads for Apple Developers web site. Use your AppStore Id to login.
- Download Command Line Tools for your Mac OS X version. (Probably Mavericks April / March 2014).
Update Mar 2018: If the above instructions fail follow the instructions here, which should be up to date: https://stackoverflow.com/questions/9329243/xcode-install-command-line-tools
Run the terminal command below. It should successfully install the nokogiri gem (an DOM parsing library).
gem install nokogiri
cd /Users/monica/lighthouse/laser_shark
bundle install
Follow the other setup instructions for that rails app. For laser_shark, you will have to edit your /etc/hosts, for example.
You will need to update the database connection settings for all your Rails applications. In config/database.yml, make sure you have the following settings for the development and test environments. Of course, replace rotten_mangoes with the name of your rails app.
development:
adapter: postgresql
database: rotten_mangoes_development
host: localhost
encoding: unicode
test:
adapter: postgresql
database: rotten_mangoes_test
host: localhost
encoding: unicode
To check if the database connection settings work, see if you can create the database.
bin/rake db:create
If you see this error, make sure Postgres database is started.
SYS:laser_shark SYS$ bin/rake db:create

You probably have XCode 5.1.1 or higher and tried to install the command line tools via command line. See Install the command line developer tools section above.
I wrote this down from memory. If any of the steps here don't work, please fork this gist, fix the issue and share with the class.
This helped me to resolve following issue:
