Download Composer Latest: v2.9.2
Windows Installer
The installer - which requires that you have PHP already installed - will download Composer for you and set up your PATH environment variable
so you can simply call composer from any directory.
Download and run Composer-Setup.exe - it will install the latest composer version whenever it is executed.
Command-line installation
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') === 'c8b085408188070d5f52bcfe4ecfbee5f727afa458b2573b8eaaf77b3419b0bf2768dc67c86944da1544f06fa544fd47') { echo 'Installer verified'.PHP_EOL; } else { echo 'Installer corrupt'.PHP_EOL; unlink('composer-setup.php'); exit(1); }"
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
--preview, --snapshot, --1 (EOL), --2, --2.2 (LTS)
Select a specific version channel instead of the default latest stable. See "Download channels" below for more details. Example:
php composer-setup.php --2.2
--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. To select the latest 2.2 LTS
you can use --2.2.
Maintenance policy
Bug fixes are only guaranteed to be provided for the latest feature release.
Critical bug and security fixes are also provided for active LTS releases (currently 2.2).
