vendorファイルの一部に不具合があり、パッチを当てることにしました。  
しかし、実行してみるとエラーが発生してしまい、パッチを当てることができません。  
`Could not apply patch! Skipping. The error was: Cannot apply patch`

次のような手順で行いました。

  1. composer-patchesをインストール  
`composer require cweagans/composer-patches`

  2. パッチファイルの保存先フォルダ `patches_composer` を作成

  3. 編集対象ファイル(Response.php)を .orig としてコピー  
`cp vendor/inertiajs/inertia-laravel/src/Response.php
vendor/inertiajs/inertia-laravel/src/Response.php.orig`

  4. 編集対象ファイル(Response.php)を編集（修正）

  5. 差分ファイルの作成  
`diff -u vendor/inertiajs/inertia-laravel/src/Response.php.orig
vendor/inertiajs/inertia-laravel/src/Response.php > patches_composer/inertia-
laravel-response.patch`  
編集対象ファイル(Response.php) とオリジナル(Response.php.orig)を比較して、  
差分ファイル(patches_composer/inertia-laravel-response.patch)を出力

  6. composer.json ファイルにパッチの情報を追加

```

        "extra": {
            "patches": {
                "inertiajs/inertia-laravel": {
                    "twice url": "patches_composer/inertia-laravel-response.patch"
                }
            }
        },
    
```

ちなみに差分ファイルの中身は次のようになっています  
※先頭行の Response.php.orig を Response.php に変更

```

### エラー

しかしながら、composer install, composer update を実行すると次のようなエラーが発生します。

```

      - Applying patches for inertiajs/inertia-laravel
        patches_composer/inertia-laravel-response.patch (twice url)
       Could not apply patch! Skipping. The error was: Cannot apply patch patches_composer/inertia-laravel-response.patch
    
```

エラーの詳細がわからないため、どのように対応すればよいのかがわかりません。  
上記の手順の中で、誤った部分があるでしょうか？

よろしくお願いします。

【追記】  
パッチファイルの先頭が「更新されるファイル」のようなので下記のように変更しました。  
`--- vendor/inertiajs/inertia-laravel/src/Rsponse.php`

`composer install -vvv` で処理の詳細を出力。

上記の動作を見ると、`inertiajs/inertia-laravel/` がアップデートされて、その後にパッチを当てているように見えます。

`can't find file to patch at input line 3`
については[無視しても良い](https://maxcluster.de/en/knowledge-

question
php composer
phpのパッチ処理 cweagans/composer-patches で エラー スキップしてしまう
解決しました。  
対象ファイルの部分を `composer.json` の指定された `inertiajs/inertia-laravel`
からの相対位置にすると上手くいきました

```
