Exercise: Verify the Dependencies

Overview

Alright! We've installed Git, Node.js, and opened our Terminal. It's now the moment of truth: have we done it correctly?

Verify Git

We need to verify that Git is both installed and available in the Terminal:

1. Open your Terminal (Node.js for Command Prompt on Windows)
2. Type: git --version
3. Verify that you received a version back:

Verify Node.js

We need to verify that Node.js is both installed and available in the Terminal:

1. Open your Terminal (Node.js for Command Prompt on Windows)
2. Type: node --version
3. Verify that you received a version back.

• It should be 0.10.x or higher.

Verify npm

The Node Package Manager (npm) is bundled with the Node.js install. However, it's version independently and I want to ensure that you have an up-to-date version:

1. Open your Terminal (Node.js for Command Prompt on Windows)
2. Type: npm --version
3. Verify that you received a version back.

• It should be 2.0.0 or higher.

If it is too low, then you can upgrade it with:

npm update -g npm

Note: You may need to add sudo in front of the command.
