This is a super basic Magento/Composer question — how are users (i.e. me) supposed to make a Magento system aware of packages installed via composer/firegento?

That is — most of the tutorials I've found cover setting up a composer.json file, and I've managed the without a problem. I can install packages into vendor to my heart's content.

They'll also mention adding the following to your composer.json so "[something]" knows where to install the modules


However, what I haven't been able to figure out with the existing documentation is what command do I need to run in order to copy or symlink the files in ./vendor into my Magento root?

The tutorials I've found say use the magento-hackathon/magento-composer-installer project on GitHub — but this project's README seems more focused on creating your own packages than on basic usage.

  • I'm assuming you've tried running "composer install"? That should be all that is needed. Apr 21, 2014 at 2:13
  • @JoeConstant Yes I have — it (looks like?) the single package I installed didn't have the correct requires to make it work. Working on an answer right now. Apr 21, 2014 at 6:35

The short version: If everything's configured correctly, you don't need to do anything. The way packages.firegento.com works is by taking advantage of a Composer custom installer plugin. This custom installer plugin handles symlinking or copying the files (depending on the value of magento-deploystrategy in the extra configuration section)

However, somewhere in your composer require configuration, you need to include the magento-hackathon/magento-composer-installer package.

"require": {
    "magento-hackathon/magento-composer-installer": "*"

This package installs the composer plugin, which in turn enables the custom installation functionality. This is why every composer plugin should have this package in its require list.

  • the last part is wrong, a magento module should not require the installer. I added an explanation for this to the Readme: github.com/magento-hackathon/magento-composer-installer/…

  • @Flyingmana I can understand why you'd say that, and it's a laudable goal, but the connect20/* packages in the FireGento repository all had this library auto-added, which means culturally speaking, the project wants its developers to add this packages as a require. It also makes sense from a usability standpoint, as expecting newbie users to completely grok the composer model seems like a mistake. Apr 27, 2014 at 23:39
  • no, simply no!!
