【Laravel6】AWSのS3パッケージインストールの際，誤ったバージョンをダウンロードしてしまった。

前提・実現したいこと

題の通りなのですが，AWSのS3パッケージインストールの際に，誤ったバージョンをダウンロードしてしまいました。
バージョンを上げる方法がわからず悶えてしまっています。

発生している問題・エラーメッセージ

現在ダウンロードしているのがleague/flysystem-aws-s3-v2なのですが，Laravel6ではleague/flysystem-aws-s3-v3を使用するようで，この状態で進めていたところ

Class 'League\Flysystem\AwsS3v3\AwsS3Adapter' not found
```というエラーが発生してしまいます。

追加でダウンロードできるか試みたのですが
```ここに言語を入力
$ composer require league/flysystem-aws-s3-v3:^1.0
./composer.json has been updated
Running composer update league/flysystem-aws-s3-v3
Loading composer repositories with package information
Updating dependencies
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - league/flysystem-aws-s3-v3[dev-master, 1.0.26, ..., 1.0.29] require aws/aws-sdk-php ^3.20.0 -> found aws/aws-sdk-php[3.20.0, ..., 3.191.1] but the package is fixed to 2.8.31 (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command.
    - league/flysystem-aws-s3-v3 1.0.0 requires aws/aws-sdk-php 3.*@dev -> found aws/aws-sdk-php[dev-master, 3.0.0-beta.1, ..., 3.191.1] but the package is fixed to 2.8.31 (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command.
    - league/flysystem-aws-s3-v3[1.0.1, ..., 1.0.25] require aws/aws-sdk-php ^3.0.0 -> found aws/aws-sdk-php[dev-master, 3.0.0-beta.1, ..., 3.191.1] but the package is fixed to 2.8.31 (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command.
    - league/flysystem-aws-s3-v3 1.0.x-dev is an alias of league/flysystem-aws-s3-v3 dev-master and thus requires it to be installed too.
    - Root composer.json requires league/flysystem-aws-s3-v3 ^1.0 -> satisfiable by league/flysystem-aws-s3-v3[1.0.0, ..., 1.0.x-dev (alias of dev-master)].

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

Installation failed, reverting ./composer.json and ./composer.lock to their original content.

から

$ composer require --with-all-dependencies　aws/aws-sdk-php
```を行いましたが

  Problem 1
    - league/flysystem-aws-s3-v2 is locked to version 1.0.3 and an update of this package was not requested.
    - league/flysystem-aws-s3-v2 1.0.3 requires aws/aws-sdk-php ~2.7 -> found aws/aws-sdk-php[2.7.0, ..., 2.8.x-dev] but it conflicts with your root composer.json require (^3.191).
```とでました。要は私がv2をを使っているからでたエラーだと思います。
