    It's already installed with Laravel, but you're trying to install a newer version, as the error clearly states. `laravel/framework v7.28.4 requires league/flysystem ^1.0.34` – miken32 Jan 07 '21 at 20:47

You're using Laravel 7 (although the same is true for Laravel 8), if you take a look at the laravel/framework composer.json file, you will see that it is requiring version 1; "league/flysystem": "^1.1"

Per composer constraints, this will allow any version from 1.1 to less than 2 (>=1.1 <2).

Now it is technically possible to install 2 different versions of a package, but I'd highly advise against it as you have to monkey with the autoloader to change the namespace for one version of the package. This answer covers the details on how to do it if you absolutely must.

If you are using laravel/framework version >= 8. Try running this command in your console. It worked for me.

composer require league/flysystem-aws-s3-v3

    Code only answers are considered low quality. Without sufficient explaination, your answer is hard to understand. If the OP can't understand your answer, then he also won't be able to reproduce your possible solution. As such it would be worthless to him/her. Please add a sufficient explaination of your possible solution. – tacoshy May 21 '22 at 03:41
