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`).

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

```mermaid
flowchart LR
    subgraph global[globale Umgebung]
        harry-1[harry v1]
    end
    subgraph stone-project[philosophers-stone-Projekt]
        stone(philosophers-stone) -->|benötigt| harry-1
    end
```

  }

  public void testIsEqualTo_apply() {
    Predicate<@Nullable Integer> isOne = Predicates.equalTo(1);

    assertTrue(isOne.apply(1));
    assertFalse(isOne.apply(2));
    assertFalse(isOne.apply(null));
  }

  public void testIsEqualTo_equality() {
    new EqualsTester()
        .addEqualityGroup(Predicates.equalTo(1), Predicates.equalTo(1))

```mermaid

        harry-1[harry v1]

    subgraph stone-project[philosophers-stone project]

```

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
```
