guzzle dependency conflict for Laravel

[cooperRjp]

Trying to add to a new Laravel project i get the following:

Problem 1
- Root composer.json requires saintsystems/odata-client ^0.2.6 -> satisfiable by saintsystems/odata-client[0.2.6].
- saintsystems/odata-client 0.2.6 requires guzzlehttp/guzzle ^6.2 -> found guzzlehttp/guzzle[6.2.0, ..., 6.5.x-dev] but it conflicts with your root composer.json require (^7.3).

Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.

You can change guzzlehttp/guzzle ^6.2 to *, then you can install the package.
