[composer-php] Remove composer

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.

For the installation I used the command curl -s https://getcomposer.org/installer | php

I am working in linux

Uninstall composer

To remove just composer package itself from Ubuntu 16.04 (Xenial Xerus) execute on terminal:

sudo apt-get remove composer

Uninstall composer and it's dependent packages

To remove the composer package and any other dependant package which are no longer needed from Ubuntu Xenial.

sudo apt-get remove --auto-remove composer

Purging composer

If you also want to delete configuration and/or data files of composer from Ubuntu Xenial then this will work:

sudo apt-get purge composer

To delete configuration and/or data files of composer and it's dependencies from Ubuntu Xenial then execute:

sudo apt-get purge --auto-remove composer

https://www.howtoinstall.co/en/ubuntu/xenial/composer?action=remove

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.

Additional information about removing/uninstalling composer

Answers above did not help me, but what did help me is removing:

1. ~/.cache/composer
2. ~/.local/share/composer
3. ~/.config/composer

Hope this helps.

If you install the composer as global on Ubuntu, you just need to find the composer location.

Use command

type composer

or

where composer

For Mac users, use command:

which composer

and then just remove the folder using rm command.
