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

```

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`**.

```mermaid

        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"
```

```

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`**.

    end

**FastAPI** provides several tools to help you deal with **Security** easily, rapidly, in a standard way, without having to study and learn all the security specifications.

But first, let's check some small concepts.

If you don't care about any of these terms and you just need to add security with authentication based on username and password *right now*, skip to the next chapters.
