The experience while I installed Laravel:

1. Usual terminal commands:

   Here is a list of common commands:

   ls

   list files and directories

   cd

   change directory

   mkdir

   create a new directory

   cp

   copy files or directories

   mv

   move (rename) files or directories

   rm

   remove files or directories

   See the Terminal Commands category for a list of useful Terminal programs.

2. The process:

   mkdir laravel in MAMP folder —>

1)install composer firstly:

Run this in your terminal to get the latest Composer version:

php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
php -r "if (hash_file('SHA384', 'composer-setup.php') === '669656bab3166a7aff8a7506b8cb2d1c292f042046c5a994c43155c0be6190fa0355160742ab2e1c88d40d5be660b410') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
php composer-setup.php
php -r "unlink('composer-setup.php');"

This installer script will simply check some php.ini settings, warn you if they are set incorrectly, and then download the latest composer.phar in the current directory. The 4 lines above will, in order:

• Download the installer to the current directory
• Verify the installer SHA-384 which you can also cross-check here
• Run the installer
• Remove the installer

WARNING: Please do not redistribute the install code. It will change with every version of the installer. Instead, please link to this page or check how to install Composer programmatically.

locally run composer

Installing Composer locally is a matter of just running the installer in your project directory. See the Download page for instructions.

The installer will just check a few PHP settings and then download composer.phar to your working directory. This file is the Composer binary. It is a PHAR (PHP archive), which is an archive format for PHP which can be run on the command line, amongst other things.

Now just run php composer.phar in order to run Composer.

You can install Composer to a specific directory by using the --install-dir option and additionally (re)name it as well using the --filename option. When running the installer when following the Download page instructions add the following parameters:

php composer-setup.php --install-dir=bin --filename=composer

Now just run php bin/composer in order to run Composer.

Basic usage of composer

For our basic usage introduction, we will be installing monolog/monolog, a logging library. If you have not yet installed Composer, refer to the Intro chapter.

Note: for the sake of simplicity, this introduction will assume you have performed a local install of Composer.

composer.json: Project Setup

To start using Composer in your project, all you need is a composer.json file. This file describes the dependencies of your project and may contain other metadata as well.

4. The command to install laravel using composer

Via Composer Create-Project

Alternatively, you may also install Laravel by issuing the Composer create-project command in your terminal:

composer create-project --prefer-dist laravel/laravel blog

In my case :  I need to use
php composer.phar create-project --prefer-dist laravel/laravel blog
