MacOS

1. Let’s check the version of the operating system.

Click the Apple menu and choose About this Mac.

Apple menu

2. In the window you will find the version of your operating system.

If your version number starts with 10.6, 10.7, 10.8, 10.9, 10.10, 10.11 10.12, 10.13, or 10.14 this guide is for you. If it’s something else, we can setup your machine at the event.

About this Mac dialog

3a. If your OS X version is 10.9 or higher:

We are installing homebrew and rbenv.

3a1. Install Command line tools on terminal:

xcode-select --install

3a2. Install Homebrew:

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

3a3. Install rbenv:

brew update
brew install rbenv
brew upgrade ruby-build
echo 'eval "$(rbenv init -)"' >> ~/.bash_profile
source ~/.bash_profile

3a4. Build Ruby with rbenv:

You can find the newest version of Ruby with the command “rbenv install -l”.

rbenv install 2.6.5

If you got "BUILD FAILED (OS X 10.14.6 using ruby-build 20191004)"

brew install openssl
RUBY_CONFIGURE_OPTS=--with-openssl-dir=/usr/local/Cellar/openssl/1.0.2t rbenv install 2.6.5

If you got “OpenSSL::SSL::SSLError: … : certificate verify failed” error, try it this way.

brew install curl-ca-bundle
cp /usr/local/opt/curl-ca-bundle/share/ca-bundle.crt `ruby -ropenssl -e 'puts OpenSSL::X509::DEFAULT_CERT_FILE'`

3a5. Set default Ruby:

rbenv global 2.6.5

3a6. Install rails:

gem install rails --no-document

3b. If your OS X version is 10.6, 10.7, or 10.8:

Download the RailsInstaller for your version of OS X:

Double click the downloaded file and it will unpack it into the current directory. Double click the the newly unpacked ‘RailsInstaller-1.0.4-osx-10.7.app’ or ‘RailsInstaller-1.0.4-osx-10.6.app’ and follow the instructions. It will open a README file with ‘Rails Installer OS X’ at the top. Please ignore the instructions in this file.

If the Rails version wasn’t the latest, you could update it using a following command on terminal.

gem update rails --no-document

4. Install a text editor to edit code files

For the workshop we recommend the text editor Atom.

If you are using Mac OS X 10.8 or older versions, you can use another editor Sublime Text 2.

5. Update your browser

Open whatsmybrowser.org and update your browser if you don’t have the latest version.

6. Check the environment

Check that everything is working by running the application generator command.

rails new testapp
cd testapp
rails server

Go to http://localhost:3000 in your browser, and you should see the ‘Yay! You’re on Rails!’ page.

Now you should have a working Ruby on Rails programming setup. Congrats!

Coach: We recommend to verify by using the scaffold command and inputting data with the generated page with coaches to ensure everything is working. Also: remove the test app testapp to make super sure no-one is working in the wrong folder, following the steps of the workshop.
