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

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

```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

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

```mermaid

    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`**.
