# Getting up and running with Ruby on Rails

TODO: Polish and send to Cayla

## Let’s get introduced to the Terminal!

- Open Spotlight and type in `terminal`
- You should see the application come up — open it
- Tada! You’ve opened the app and can start running fancy computer commands now

## Learning basic terminal commands

- Create a new directory (aka: a folder) for us to put our Rails projects in. Type in `mkdir learning-rails` and hit Return (this will run the command).
	- `mkdir` means “create a new directory”
	- `learning-rails` is the name we want to give to the directory
	- This is the same as creating a new folder in Finder. (Note: You can actually open Finder and see the new folder you just created.)

## Bonus

- Press Cmd+Space to open spotlight quickly
- Not sure why we're getting permissions errors installing rails. Tried fixing with `sudo chown -R caylahanousek:staff ~/.rbenv && sudo chown -R caylahanousek:staff ~/.gem`

- Basic terminal (make a directory and cd into it)
- http://rubyonrails.org/download/
- Make sure xcode command line tools are installed
	- http://railsapps.github.io/xcode-command-line-tools.html
	- `xcode-select --install` worked on Cayla's computer
	- `xcode-select -p` to make sure it's installed
- Homebrew
	- http://brew.sh/
- rbenv
	- https://robots.thoughtbot.com/using-rbenv-to-manage-rubies-and-gems
- vim for text editing
	- update bash profile: `vim ~/.bash_profile`
	- Hit `i` and paste
	- Escape, `:wq`, enter (save and exit)
- Add this to your `.bash_profile`: `eval "$(rbenv init -)"`
	- This allows shims and autocompletions in rbenv
- Install latest stable version of Ruby
	- https://www.ruby-lang.org/en/downloads/
```
rbenv install 2.2.2
rbenv global 2.2.2
```
