Angular 8 Installation (How to install Angular 8 or Angular 8 Environment setup) Before to setup environment for Angular development using the Angular CLI tool, you must have installed Node.js on your system and set a development environment and npm package manager. The Angular team had announced about Angular CLI tool that makes creating and scaffolding Angular 2 applications incredibly easy in the NG-Conference 2016.Angular CLI is a command line interface for you to work with Angular and also to automate your development workflow.

Angular CLI Options

We ran the command: ng new my-new-project which is the bare minimum requirements for using the CLI to start a new project.

Installation on UNIX/Linux/Mac OS X, and SunOS. Based on your OS architecture, download and extract the archive node-v6.3.1-osname.tar.gz into /tmp, and then, finally move extracted files into/usr/local/nodejs directory. This is probably very trivial, but I am hitting my head against the wall while I am trying to (unsuccessfully) install angular-cli. I am following the official angular-cli documentation here. Mkotsollariss-MacBook-Pro: mkotsollaris$ npm -v 5.6.0 mkotsollariss-MacBook-Pro: mkotsollaris$ node -v v8.9.4 Then I run npm install -g angular-cli. To install the Angular Command Line Interface, or CLI onto your development machine, first install both node and the Node Package Manager, or NPM. After the developer has installed both node and and the Node Package Manager, or NPM onto his or her development machine, the Angular CLI may then be installed globally using npm, as follows.

However, there are other flags you can pass to the ng new command. The official Angular CLI wiki page will show you all of the commands, and if you click on the ng new command, you will find that it supports the following flags:

The documentation allows you to click on each option above, providing you with the actual flag to use during installation, and the default value.

So, for instance, if you wanted to set up your new Angular 5 project to work with Sass styling, you would run the following command:

Another common flag I add to new projects that I know will require routing is:

Then, of course, if you wanted to combine the two above (a project with Sass support and routing), like we did with our initial project:

This will setup the basic scaffolding to handle an Angular 5 app with multiple routes (or put differently, multiple URL's).

I won't run through all of the other options, as you can use the documentation to see what they offer based on your needs.

Installing Angular 4 without the CLI

If you prefer to install Angular 4 without the command line tool, you can install it manually with the help of the Angular Quickstart.

Angular Cli Windows

At the time of writing this tutorial, there is not an Angular 4 Quickstart repository. The current quickstart is based on Angular 2. Still, you can use git to clone the quickstart and run through the upgrade process outlined above.

To use the Angular 2 Quickstart, you run:

Note: You will need the git command line tool to run the above command.

After it's installed:

If it's installing an Angular 2 project, this is the point where you need to upgrade it manually using npm:

To upgrade, paste (Mac only):

To upgrade, paste (PC only):

Then, we need to make sure we're using Typescript 2.1.6 or higher (you can skip this step if your CLI installs Angular 4 by default):

Angular Cli Command

And that's how you install (and upgrade, if need be) an Angular 4 project using the Angular CLI.

Note: If you use this method, you will not be able to utilize the various helpful commands provided by the Angular-CLI while developing your Angular 4 app.
