#WDI Seattle Install Fest
For the first portion of the class, we'll be working exclusively inside of the browser and Node. We'll be installing the following tools.
- Homebrew
- Git
- Node
- Oh my ZSH
- iTerm
- Postgres.app
- Ruby
- Rails
##Homebrew Homebrew is a package manager that we will use to install various command line tools in our class.
Open up terminal, and paste the following command to install Homebrew. You might be prompted to install XCode Command Line Tools during the install process.
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
You may be prompted to installed xcode command line tools. When prompted, click and install through that, and you're homebrew installation will continue.
After the installation process, run the command brew doctor. If any warnings or errors are displayed, we will need to resolve them before proceeding with the rest of the install fest.
##GIT Before we do this process, please make sure you have signed up for an account on Github. We will be installing a version of GIT from home brew and also configuring it.
To install GIT
brew install git
####Configuring GIT
Using your email credentials for GIT, run these commands with your user and email configured.
git config --global user.name "YOUR-USERNAME"
git config --global user.email YOUR-EMAIL-ADDRESS
git config --global push.default simple
git config --global credential.helper cache
####Setting up SSH Key You might find your self having to re-authenticate GIT every time you work on your command line. Setup SSH Keys to let Github remember your machine in the future.
##Node We'll be using the official Node installer provided from nodejs.org
Download and run the installer. The installation usually goes smoothly, and you can verify Node is working by restarting terminal, and typing
Verify the installation afterwards by running
node -v
npm -v
The above should display without any errors.
To finish up your installation, run this command to allow for global installations of npm tools.
sudo chown -R $USER /usr/local/lib
##Sublime 3 We'll be running Sublime 3, not Sublime 2 as our text editor of choice.
Download and install version 3 from http://www.sublimetext.com/3
It is a pretty typical installation for an app, but we need to add a shortcut so we can load sublime from the Terminal.
ln -s /Applications/Sublime\ Text.app/Contents/SharedSupport/bin/subl /usr/local/bin/subl
Restart terminal, and you should be able to open a folder to edit by typing subl .
##ZSH Oh my ZSH?!!! We will be tricking out commandline with another shell. A shell is an interface into our computer, and we will be using a lot to run commands.
We'll be using a shell and configuration package called Oh-My-Zsh
To install, we will run
curl -L http://install.ohmyz.sh | sh
Restart Terminal, and you should see a brand new and colorful command prompt.
##iTerm For those running, mac, download iterm2, a better featured terminal. iterm2
Drag and drop into your Applications folder.
##Postgres.app We will be using a relational database called Postgres for Node and Rails portion our class. Download
Download and install from http://postgresapp.com/
If you have successfully configured zsh and sublime, the following command should work.
subl ~/.zshrc
Your sublime editor will popup with configuration settings, at the bottom of the file append
export PATH=$PATH:/Applications/Postgres.app/Contents/Versions/9.4/bin
Save the file, close Sublime, and restart your terminal.
Type which psql at which point should display
/Applications/Postgres.app/Contents/Versions/9.4/bin/psql
