如何在 Mac 上安装 Composer？

Question

I'm trying to get the Laravel PHP framework installed and for that I need to install Composer. However I'm getting stuck there. I installed it before for Symfony but I couldn't get it to work so I think I deleted it.

When I open the terminal on Mac and enter one of the commands for installing composer like:

curl -sS https://getcomposer.org/installer | php

I get:

-bash: php: command not found
curl: (23) Failed writing body (0 != 1635)

Why is this?

Answer 1

You can install it via Brew.

First, install Brew ;

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Then you can use Brew to install Composer;

brew install composer

That's it, it's now installed. You can verify this by running composer --version

Answer 2

1. download file from https://getcomposer.org/installer

2. execute the file

sudo php installer

3. and move the file

mv composer.phar /usr/local/bin/composer

Answer 3

Here it is:

curl -s https://getcomposer.org/installer | php
sudo mv composer.phar /usr/local/bin/composer

Answer 4

First install brew if not installed in Mac:

$ ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Update brew and install php and composer.

$ brew update
$ brew install php
$ brew install composer

Verify by checking version:

 $ composer -V

I hope it helps.
