composer is ignoring installer-paths configuration

cakephp, composer-php, php

Solution

From the documentation.

You cannot use this to change the path of any package. This is only applicable to packages that require composer/installers and use a custom type that it handles.

From one of the packages you're installing:

{
    "name": "smottt/wideimage",
    "description": "An open-source PHP library for image manipulation. (With namespaces, PHP 5.3+)",
    "homepage": "http://wideimage.sourceforge.net",
    "type": "library",
    "license": ["GPL-2.0","LGPL-2.1"],
    "version": "11.02.19",
    "autoload": {
        "psr-0" : {
          "WideImage" : "lib/"
        }
    }
}

So basically the package you're trying to install doesn't support custom install paths.

Problem

I'm try using CakePHP for the first time with composer, but I have some problems. I have this `composer.json`: ``` { "name": "example.com.br", "repositories": [ { "type": "pear", "url": "http://pear.cakephp.org" } ], "config": { "vendor-dir": "Vendor/" }, "require": { "php": ">=5.4", "pear-cakephp/cakephp": ">=2.4.3", "cakephp/debug_kit": "2.2.*", "smottt/wideimage": "dev-master" }, "extra": { "installer-paths": { "app/Plugin/DebugKit": ["cakephp/debug_kit"], "app/Vendor/Wideimage": ["smottt/wideimage"] } } } ``` When I run `composer install (or update) --prefer-dist`, everything works except `smottt/wideimage`. This package is being installed in the `/Vendor` folder instead `/app/Vendor`, so, installer-paths was ignored.
