Например, вы можете создать проект `philosophers-stone`, который зависит от пакета **`harry` версии `1`**. Значит, нужно установить `harry`.

```mermaid
flowchart LR
    stone(philosophers-stone) -->|requires| harry-1[harry v1]
```

Затем вы создаёте другой проект `prisoner-of-azkaban`, который тоже зависит от `harry`, но ему нужен **`harry` версии `3`**.

```mermaid
flowchart LR

```mermaid
flowchart LR
    stone(philosophers-stone) -->|requires| harry-1[harry v1]
```

Então, em algum momento depois, você cria outro projeto chamado `prisoner-of-azkaban`, e esse projeto também depende de `harry`, mas esse projeto precisa do **`harry` versão `3`**.

```mermaid
flowchart LR

```mermaid
flowchart LR
    stone(philosophers-stone) -->|requires| harry-1[harry v1]
```

Luego, en algún momento después, creas otro proyecto llamado `prisoner-of-azkaban`, y este proyecto también depende de `harry`, pero este proyecto necesita **`harry` versión `3`**.

```mermaid
flowchart LR

```mermaid
flowchart LR
    subgraph global[globale Umgebung]
        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-Projekt]
        stone(philosophers-stone) -.-x|⛔️| harry-1
    end
    subgraph azkaban-project[prisoner-of-azkaban-Projekt]

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.
