如果你想運行 `philosophers-stone`，你需要先安裝 `harry` 版本 `1`，例如：

<div class="termy">

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

</div>

然後你會在全域 Python 環境中安裝 `harry` 版本 `1`。

```mermaid
flowchart LR
    subgraph global[全域環境]
        harry-1[harry v1]
    end
    subgraph stone-project[專案 philosophers-stone]
        stone(philosophers-stone) -->|需要| harry-1
    end
```

如果你想运行 `philosophers-stone`，你需要首先安装 `harry` 版本 `1`，例如：

<div class="termy">

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

</div>

然后你将在全局 Python 环境中安装 `harry` 版本 `1`。

```mermaid
flowchart LR
    subgraph global[全局环境]
        harry-1[harry v1]
    end
    subgraph stone-project[工程 philosophers-stone]
        stone(philosophers-stone) -->|需要| harry-1
    end
```
