I installed composer while trying to install cakePhp, but the installation was not successful and I want to uninstall composer. I am not finding any way to do this.
curl -sS https://getcomposer.org/installer | sudo php
sudo mv composer.phar /usr/local/bin/composer
export PATH="$HOME/.composer/vendor/bin:$PATH"
If you have installed by this way simply
Delete composer.phar from where you've putted it.
In this case path will be /usr/local/bin/composer
Note: There is no need to delete the exported path.
