1. Open Terminal and paste these code and run
php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
php -r "if (hash_file('sha384', 'composer-setup.php') === '8a6138e2a05a8c28539c9f0fb361159823655d7ad2deecb371b04a83966c61223adc522b0189079e3e9e277cd72b8897') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
php composer-setup.php
php -r "unlink('composer-setup.php');"
2. It will install composer locally. Now we need to move it globally
sudo mv composer.phar /usr/local/bin/composer
3. If you facing the following problem
mv: rename composer.phar to /usr/local/bin/composer: No such file or directory
Then run these command to create the expected directory.
Step 1: cd ~ Step 2: sudo mkdir -p /usr/local/bin Step 3: curl -sS https://getcomposer.org/installer | sudo php -- --install-dir=/usr/local/bin --filename=composer
And run these command again.
sudo mv composer.phar /usr/local/bin/composer
Now it should work. Done 🙂
