Install Node.js binary distribution
How to install Node.js and npm on Mac OS with Homebrew. The easiest way to install node.js and npm is the Homebrew package manager, which means you must first install Homebrew on your Mac if you haven't already. It's always a good idea to upgrade Homebrew before installing the Homebrew package, so run the following command to do so. Note: Due to the use of nodejs instead of node name in some distros, yarn might complain about node not being installed. A workaround for this is to add an alias in your.bashrc file, like so: alias node=nodejs.This will point yarn to whatever version of node you decide to use. If Yarn is not found in your PATH, follow these steps to add it and allow it to be run from anywhere.
Node.js installation is a simple task. We just need the right steps. In this tutorial, we shall learn to setup environment for Node.js and the prerequisites to start developing Node.js applications.
Node Js Windows
JavaScript programming language is used for Node.js Application Development. The source files of Node.js applications have extension of '.js'. Any text editor is sufficient to write Node.js code and save it as .js file.
To interpret the instructions written in the source .js files, Node.js interpreter is required. The Node.js is available as a binary distribution.
Download Node.js
Download the latest binary distribution from [https://nodejs.org/download/release/latest/]. Based on the Operating System and Architecture, download a suitable package. The size would be less than 20MB.
Following are the latest packages available at the time of writing this tutorials (for x64).
For linux kernel based OS like Ubuntu/MacOS/SunOS
Once the download is complete, extract the package and include it in the system path variable.
Go to the downloaded folder, Open a Terminal from there and execute the following commands.
Unzip the compressed package
Make nodejs directory in /usr/local/. Replace the file name, if it is different from what you have downloaded.
Move the extracted nodejs package to /usr/local/nodejs/. Provide user password if asked.
Add the path /usr/local/nodejs/bin to PATH environment variable. Provide user password if asked.
Open .bashrc file and append the nodejs' path at the end. To edit .bashrc, open a terminal and run the following command :
Add the following line at the end of .bashrc file.
Once after adding the line, close the terminal and reopen again.
To verify if nodejs path has been added to PATH environment variable, run the following command :
For Windows OS, the value echoed back should have /usr/local/nodejs/bin.
For installing Node.js on Windows Operating System, double click on the .msi file and follow the prompt step by step. Finishing the prompt should install Node.js with PATH added to the environment variables.
Verify Node.js installation
Using a Text Editor, create a sample file with name verifyNode.js and copy paste the following content to that file.
verifyNode.js
And run the following command in Command prompt or Terminal from the directory of verifyNode.js script file.
Output
Node Js Install
