composer require error

[dharmikvyas]

Hello, I want to add CRM to my existing school management software. I am getting following error.

Problem 1
    - Root composer.json requires banckle/crm-laravel dev-master -> satisfiable by banckle/crm-laravel[dev-master].
    - banckle/crm-laravel dev-master requires illuminate/support 4.1.* -> found illuminate/support[v4.1.0, ..., 4.1.x-dev] but these were not loaded, likely because it conflicts with another require.
  Problem 2
    - Root composer.json requires venturedrake/laravel-crm ^0.10.1 -> satisfiable by venturedrake/laravel-crm[0.10.1].
    - venturedrake/laravel-crm 0.10.1 requires guzzlehttp/guzzle ^7.3 -> found guzzlehttp/guzzle[dev-master, 7.3.0, ..., 7.5.x-dev (alias of dev-master)] but it conflicts with your root composer.json require (^6.3).

Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.
You can also try re-running composer require with an explicit version constraint, e.g. "composer require venturedrake/laravel-crm:*" to figure out if any version is installable, or "composer require venturedrake/laravel-crm:^2.1" if you know which you need.

This is a standalone app, not something you can really require for another application.
