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

Solution 1:

During the installation you got a message Composer successfully installed to: ... this indicates where Composer was installed. But you might also search for the file composer.phar on your system.

Then simply:

1. Delete the file composer.phar.
2. Delete the Cache Folder:
   • Linux: /home/<user>/.composer
   • Windows: C:\Users\<username>\AppData\Roaming\Composer

That's it.

Solution 2:

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
