Hi, I am having a problem trying to install the lumen installer on my El Capitan computer. This is the command line I launch:
composer global require "laravel/lumen-installer"
I also tried it as sudo but it gives me the following error:
Your requirements could not be resolved to an installable set of packages.
Here is the complete output of the command:
Changed current directory to /Users/mmarteau/.composer
Using version ^1.0 for laravel/lumen-installer
./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

Installation failed, reverting ./composer.json to its original content.
I Googled it a little and self updated composer but nothing changes, if someone can help, it would be super :)
Have a good night everyone
The problem occured because you've already install package symfony/process ~3.* globally, and lumen installers require symfony/process ~2.3 so composer cannot install both. You can resolve this by install lumen installers dev-master branch by simply running:
composer global require "laravel/lumen-installer=dev-master"
until there is an official release.
