Downloading and Installing Composer on Linux

Composer provides an installer written in PHP. We have to download it, make sure it isn't corrupted, and then use it to install Composer.

Make sure you are in your home directory and then download the installer with curl :

cd ~
curl -sS https://getcomposer.org/installer -o composer-setup.php

Next, make sure the installer hash matches the SHA-384 hash for the latest installer in Composer Public Keys / Signatures . Copy the hash from this page and save it as a command line variable:

HASH=544e09ee996cdf60ece3804abc52599c22b1f40f4323403c44d44fdfdd586475ca9813a858088ffbc1f233e9b180f061

Be sure to replace the last hash with the one highlighted in red.

Now run the following PHP script to make sure the install script is safe to run:

php -r "if (hash_file('SHA384', 'composer-setup.php') === '$HASH') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"

You should see the following output:

Installer verified

If you see Installer corrupt , you need to download the install script again and re-verify that you are using the correct hash. Run the command and check the installer again. Once the installer has successfully verified, you can proceed.

To install composer globally, use the following command, which will download and install composer as a system-wide composer command in the / usr / local / bin directory :

sudo php composer-setup.php --install-dir=/usr/local/bin --filename=composer

The output should look like this:

All settings correct for using Composer
Downloading...

Composer (version 1.6.5) successfully installed to: /usr/local/bin/composer
Use it: php /usr/local/bin/composer

To test the installation, run the command:

composer

You should get similar output with Composer version and arguments.

. . .

This means that the Composer dependency manager has been successfully installed and is available system-wide.

Note: if you prefer to have separate Composer executables for each project you host on this server, you can install locally for each project. NPM users should be familiar with this approach. This method is also useful when the system user does not have system-wide rights to install software.

To do this, use the php composer-setup.php command. This will generate a composer.phar file in the current directory, which can be executed using the ./composer.phar command.

Original:

Installing and Using Composer on Ubuntu 18.04

Installing composer using the Windows command line

Start the Windows console and use the cd command to navigate to the desired folder.

Execute the following commands one by one:

php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
php -r "if (hash_file('sha384', 'composer-setup.php') === '756890a4488ce9024fc62c56153228907f1545c228516cbf63f885e036d37e9a59d27d63f46af1d4d07ee0f76181c7d3') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
php composer-setup.php
php -r "unlink('composer-setup.php');"

If the installation was not performed, then the checksum has changed. Go to link and get new installation commands
