発生している問題・エラーメッセージ

https://readouble.com/laravel/5.5/ja/passport.html
にあるようにcomposer require laravel/passportでパッケージをインストールしようとするとこのようなエラーが出ます

Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Installation request for laravel/passport ^5.0 -> satisfiable by laravel/passport[v5.0.0].
    - Conclusion: remove laravel/framework v5.5.35
    - Conclusion: don't install laravel/framework v5.5.35

該当のソースコード

composer.json

    "require": {
        "php": ">=7.0.0",
        "asvae/laravel-api-tester": "^2.0",
        "doctrine/dbal": "^2.6",
        "fideloper/proxy": "~3.3",
        "laravel/framework": "5.5.*",
        "laravel/tinker": "~1.0"
    },

試したこと

don't install laravel/framework v5.5.35と合ったので "laravel/framework": "5.5.*",を削除してコンポーサーをアップデート下後再度パッケージのインストールを試しましたが結果同じエラーが出ました

こちらで質問されていることが似ている現象かと思い
https://github.com/dingo/api/issues/1076
"laravel/framework": "5.5.*",は削除せずに"phpdocumentor/reflection": "3.x@dev"を追記し下記のコマンドを実行しました
$ composer update
$ composer require dingo/api:1.0.x@dev

結果

Your requirements could not be resolved to an installable set of packages.

Installation failed, reverting ./composer.json to its original content.

これらのエラーはそれぞれのパッケージが合わずに出ているものなのでしょうか？
こういう風に変更すれば解決するのでは、と何か思い当たる節がある方いらっしゃいましたらご教授いただけませんでしょうか

または公式のクライアント認証実装方法以外で実装する方法などありますでしょうか？
