Sau đó, vào một vài thời điểm sau, bạn tạo một dự án khác được gọi là `prisoner-of-azkaban`, và dự án này cũng phụ thuộc vào `harry`, nhưng dự án này cần **`harry` phiên bản `3`**.

```mermaid
flowchart LR

        byte[] buf = new byte[outlen];
        int carry = 0;
        for (int i = lcm - 1; i >= 0; i--) {
            carry = carry_add(data, buf, carry, i);
        }

        if (carry != 0) {
            for (int i = outlen - 1; i >= 0; i--) {
                carry += buf[i] & 0xff;
                buf[i] = (byte) (carry & 0xff);
                carry >>>= 8;
            }
        }
        return buf;

```mermaid

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

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`**.

```mermaid

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]
```

```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
    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

        harry-1[harry v1]
    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"
```
