```mermaid

    end
    subgraph stone-project[philosophers-stone project]
        stone(philosophers-stone) -->|requires| harry-1
    end
```

그리고 다시 `마법사의 돌(philosophers-stone)`을 실행하려고 하면, **작동하지** 않을 수 있습니다. 왜냐하면 이 프로그램은 `harry` `v1`버전을 필요로 하기 때문입니다.

```mermaid
flowchart LR
    subgraph global[global env]
        harry-1[<strike>harry v1</strike>]
        style harry-1 fill:#ccc,stroke-dasharray: 5 5
        harry-3[harry v3]
    end
    subgraph stone-project[philosophers-stone project]
        stone(philosophers-stone) -.-x|⛔️| harry-1
    end

如果你想運行 `philosophers-stone`，你需要先安裝 `harry` 版本 `1`，例如：

<div class="termy">

```console
$ pip install "harry==1"
```

</div>

然後你會在全域 Python 環境中安裝 `harry` 版本 `1`。

```mermaid
flowchart LR
    subgraph global[全域環境]
        harry-1[harry v1]
    end
    subgraph stone-project[專案 philosophers-stone]
        stone(philosophers-stone) -->|需要| harry-1
    end
```

如果你想运行 `philosophers-stone`，你需要首先安装 `harry` 版本 `1`，例如：

<div class="termy">

```console
$ pip install "harry==1"
```

</div>

然后你将在全局 Python 环境中安装 `harry` 版本 `1`。

```mermaid
flowchart LR
    subgraph global[全局环境]
        harry-1[harry v1]
    end
    subgraph stone-project[工程 philosophers-stone]
        stone(philosophers-stone) -->|需要| harry-1
    end
```

   *     however, that passing an explicit {@code null} cause prevents anyone from calling {@link
   *     #initCause} later, so it is not quite equivalent to using a constructor that omits the

    end
```

Но если затем вы захотите запустить `prisoner-of-azkaban`, вам нужно будет удалить `harry` версии `1` и установить `harry` версии `3` (или просто установка версии `3` автоматически удалит версию `1`).
