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

しかし、 `prisoner-of-azkaban` （アズカバンの囚人）を実行したい場合は、`harry` （ハリー）のバージョン `1` をアンインストールし、`harry` （ハリー）のバージョン `3` をインストールし直す必要があります。（あるいは、単に`harry` （ハリー）のバージョン `3` をインストールすることで、自動的にバージョン `1` がアンインストールされます）

<div class="termy">

```console
$ pip install "harry==3"
```

```

하지만 이제 문제가 생깁니다. 로컬 가상 환경 대신에 전역 환경에 패키지를 설치하게 되면, 어떤 버전의 `harry`를 설치할지를 선택해야 하기 때문입니다.

예를 들어, `마법사의 돌(philosophers-stone)`을 실행하고 싶다면 먼저 `harry` `v1` 버전을 다음과 같이 설치 해야 합니다:

<div class="termy">

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

</div>

그러면 결국 전역 Python 환경에는 `harry` `v1`버전이 설치된 상태가 됩니다.
