Then, at some point later, you create another project called `prisoner-of-azkaban`, and this project also depends on `harry`, but this project needs **`harry` version `3`**.

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`**.

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`**.

例如，你可能會建立一個名為 `philosophers-stone` 的專案，這個程式依賴於另一個名為 **`harry` 的套件，並使用版本 `1`**。因此，你需要安裝 `harry`。

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

然而，在此之後，你又建立了另一個名為 `prisoner-of-azkaban` 的專案，而這個專案也依賴於 `harry`，但需要的是 **`harry` 版本 `3`**。

```mermaid
flowchart LR
    azkaban(prisoner-of-azkaban) --> |需要| harry-3[harry v3]
```

例如，你可能会创建一个名为 `philosophers-stone` 的工程，这个程序依赖于另一个名为 **`harry` 的软件包，使用版本 `1`**。因此，你需要安装 `harry`。

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

然而在此之后，你又创建了另一个名为 `prisoner-of-azkaban` 的工程，这个工程也依赖于 `harry`，但是这个工程需要 **`harry` 版本 `3`**。

```mermaid

    azkaban(prisoner-of-azkaban) --> |需要| harry-3[harry v3]
```

```

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.

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

```mermaid
flowchart LR
    subgraph global[globale Umgebung]

        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]
