Composer: Command Not Found

I am using CentOS and had same problem.

I changed /usr/local/bin/composer to /usr/bin/composer and it worked.

Run below command :

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

Verify Composer is installed or not

composer --version

This is for mac or ubuntu user, try this on terminal

curl -sS https://getcomposer.org/installer | sudo php -- --install-dir=/usr/local/bin --filename=composer
