Create composer.lock as minimun required platform

[gmsantos]

Create composer.lock emulating minimum PHP version for Laravel 5.4 avoid errors like the reported here laravel/framework#20214 , keeps the lock file for faster installations and allow to relax dependencies constraint again.

@taylorotwell is this .sh still used to generate http://cabinet.laravel.com/ files? It's not used on NewCommand as far I know.

i don't think it's the solution, because it force users of php ~7.0 to do a composer update to have most recent packages. i think we need a php5.x-latest.zip and a php7.x-latest.zip

They will not get the latest only for packages that require php >= 7.0. All the other packages will came with the most recent version defined by the constraint.

Having a cabinet package by PHP version will require minor versions too (php7.1-latest.zip, php7.2-latest.zip), even patch because this requirement is in package domain. It's a nice solution but depends to update the package builder, modify the NewCommand and release a new tag for Laravel Installer.

With this approach we only have to include a new line on the .sh package builder. The drawback is to do a composer update on newer PHP versions (PHP 7.0+) vs breaking a supported version (PHP 5.6 with Laravel 5.4). At least all scenarios will have a up and running Laravel project.

I'm not sure this is needed anymore since we're requiring a more specific version of the inflector now?

yes it's actually fixed, but the problem remain, if another package drop the support of php5.6, it will happens again.

[themsaid]

@taylorotwell yes I believe this isn't needed anymore

[taylorotwell]

Added this to the laravel build server.

@taylorotwell @themsaid can laravel/framework#20227 be reverted?

Also if zipper.sh isn't used anymore I suggest to remove it from installer.
