Download Composer Latest: v2.1.12

To quickly install Composer in the current directory, run the following script in your terminal. To automate the installation, use the guide on installing Composer programmatically.

php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
php -r "if (hash_file('sha384', 'composer-setup.php') === '906a84df04cea2aa72f40b5f787e49f22d4c2f19492ac310e8cba5b96ac8b64115ac402c8cd292b8a03482574915d1a8') { 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

Most likely, you want to put the composer.phar into a directory on your PATH, so you can simply call composer from any directory (Global install), using for example:

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

For details, see the instructions on how to install Composer globally.

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.

Notable Installer Options

--install-dir

You can install composer to a specific directory by using the --install-dir option and providing a target directory. Example:

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

--filename

You can specify the filename (default: composer.phar) using the --filename option. Example:

php composer-setup.php --filename=composer

--version

You can install composer to a specific release by using the --version option and providing a target release. Example:

php composer-setup.php --version=1.0.0-alpha8

--help

The installer provides more options for specific environments, use the --help option to see all of them.

Download channels

By default the installer and composer self-update will download the latest stable version only. You may select a different download channel though.
If you would like to help test pre-release versions you can use the --preview flag on either the installer or self-update.
For snapshot builds, which are done from the latest Composer commit, you can use the --snapshot flag.
To programmatically install specific major versions you can use the --1 or --2 flag. Example:

php composer-setup.php --preview
