Confused by Node.js installation to use Angular.js

Question

I'm going through the tutorial provided by Angular( https://docs.angularjs.org/tutorial ) but I'm confused by the Node.js installation. I already have node installed globally on my mac. In the tutorial it states:

The tutorial instructions, from now on, assume you are running all commands from within the angular-phonecat directory.

Is the tutorial assuming that I do not have Node.js installed on my local machine? Or are these instructions for installing Node.js into my project folder? https://docs.angularjs.org/tutorial#install-node-js

When I run the command:

node --version

I get the result:

v7.4.0

And I get that result running the command in a new terminal as well.

Answer 1

The tutorial assumes that node is installed but you are running any commands from inside the angular-phonecat directory.

ie in a terminal you should cd to the angular-phonecat directory and run whatever commands are instructed.

cd /path/to/angular-phonecat
node start

It sounds like your set up is fine but you should verify you are running a compatible version of NodeJS.

Answer 2

You have node installed correctly already.

The bit about being in the angular-phonecat directly is just making sure you are in the directory where the package.json file is. When you run say npm install it will look in your current directory for a package.json file. So the demo just wants to make sure when they tell you to run commands that you are in the right directory.
