Unable to install with composer on Lumen 5.5

[retnek]

When I call composer require websight/l5-google-cloud-storage I got the following output:

Your requirements could not be resolved to an installable set of packages.
Problem 1
- Installation request for websight/l5-google-cloud-storage ^1.1 -> satisfiable by websight/l5-google-cloud-storage[v1.1.0].
- Conclusion: remove illuminate/contracts v5.5.28
- Conclusion: don't install illuminate/contracts v5.5.28

It is not compatible with Lumen 5.5.2?

Master is compatible. Yet this package switched to another flysystem driver and the implementation was not completed yet.

This very much means: Yes it's compatible, but may need some work and your constraint should be dev-master instead of ^1.1.

If you feel you want to use a stable version, I'd also happily review your pull requests :)

Yes, You're right! If You use Lumen You need more complex tasks to work with this package, such as define filesystem singleton and Storage class alias in bootstrap/app.php. I'm trying to put it together.

[cedricziel]

This package is very simple - if you want to, you can also initialize the flysystem adapter manually

[retnek]

Lumen does not include the filesystem (among other typical Laravel services) out of the box. So it must be initialize manually before use this package (as described here). But now it seems to work fine with the dev-master.
