This was the first in a series of posts leading up toNode.js Knockout on how to use node.js.

I have been given permission to repost the articles from the contest here (in wheat format) for general consumption. Expect more to come.

In this post we detail how to install node on Mac, Ubuntu, and Windows.

Mac

You can check it worked with a simple Hello, World! example.

Debian (Ubuntu/ Mint)

With Aptitude package manager one can install the package nodeJS then edit there bash to redirect the command node to nodejs.

sudo apt-get update
sudo apt-get install nodejs
sudo apt-get install npm

nano (edit / vim) the file ~/.bashrc and add the line: Allias node="nodejs"

Redhat (Fedora / CentOs)

Simply install from official repos:

sudo yum install nodejs npm

If that fails, enable EPEL repo:

curl --silent --location https://rpm.nodesource.com/setup | bash -

Then simply install from repo:

yum -y install nodejs

Gentoo

In portage tree:

emerge nodejs

Archlinux

In official repo use pacman package manager:

pacman -S nodejs npm

Linux from source

Thanks to code-diesel for the Ubuntu dependencies.

Windows

Currently, you must use cygwin to install node. To do so, follow these steps:

1. Install cygwin.

2. Use setup.exe in the cygwin folder to install the following packages:

   • devel → openssl
   • devel → g++-gcc
   • devel → make
   • python → python
   • devel → git

3. Open the cygwin command line withStart > Cygwin > Cygwin Bash Shell.

4. Run the below commands to download and build node.

Hello Node.js!

Here's a quick program to make sure everything is up and running correctly:

Run the code with the node command line utility:

> node hello_node.js
Server running at http://127.0.0.1:8124/

Now, if you navigate to http://127.0.0.1:8124/ in your browser, you should see a nice message.

Congrats!

You've installed node.js.
