Install Angular 2 (v11)

Here you will learn how to install the latest version of Angular 2.

Before installing Angular, you need to install some prerequisites. Angular uses NPM (Node Package Manager) to install libraries, packages and also to execute scripts. So, you need to install NPM before installing Angular.

Angular requires a current, active LTS or maintenance LTS version of Node.js and NPM.

Open terminal/command window and type node -v command to check whether the Node.js is installed on your local machine or not. If it is already installed, then it will display the version number, as shown below.

C:\Users\xyz> node -v v14.18.0

If the above command does not display the version number then it means Node.js is not installed. To install the latest version of Node.js, go to https://nodejs.org and download the installer for your platform and install it. This will install Node.js and NPM (Node Package Manager) on your local machine.

Update NPM

Angular requires NPM v6.11 or later. Check the NPM version on your local machine by opening a terminal/command window and type the following command:

>npm -v 6.14.4

This will display the version number of NPM installed on your local machine. If you don't have the latest version of NPM, then update it using the following command on Windows.

npm install -g npm

If you are on MAC, use sudo npm install -g npm command.

After installing Node.js and NPM, install the Angular CLI.

Install Angular CLI

Angular provides many libraries and packages for application development. You can install libraries required for your application using Angular CLI (Command Line Interface). Angular CLI is also used to generate, build, run, and deploy Angular application.

To install the Angular CLI globally using NPM, open a terminal/command window, and enter the following command:

npm install -g @angular/cli@latest

In the above command -g indicates global, so that you can use angular CLI anywhere on your local machine. @latest is specifies to install the latest verion of angular CLI.

After the installation, check the Angular version using the ng --version command in the terminal/command window, as shown below.

Use ng help command to see all the CLI commands, as shown below.

Note:

Angular CLI use Package.json in your application to install all the necessary libraries and packages for your application, including the required Angular framework libraries.

Visual Studio Code

Most Angular developers prefer to use Visual Studio Code for Angular application development. It's free and open-source.

To install VS Code, go to https://code.visualstudio.com , download, and install it.

Now, you are ready to develop Angular applications. Learn how to generate an initial angular application using Angular CLI next.
