환경을 활성화한 뒤, 그 안에 패키지를 설치할 수 있습니다.

/// tip

프로젝트에 필요한 패키지를 설치하거나 업그레이드할 때는 **한 번**만 하면 됩니다.

버전을 업그레이드하거나 새 패키지를 추가해야 한다면 **다시 이 작업을** 하게 됩니다.

///

### 패키지 직접 설치 { #install-packages-directly }

급하게 작업 중이고 프로젝트의 패키지 요구사항을 선언하는 파일을 사용하고 싶지 않다면, 패키지를 직접 설치할 수 있습니다.

/// tip

프로그램에 필요한 패키지와 버전을 파일(예: `requirements.txt` 또는 `pyproject.toml`)에 적어두는 것은 (매우) 좋은 생각입니다.

///

//// tab | `pip`

        final Object value = initParamMap.get(AUTHENTICATIONS_PROPERTY);
        if (value == null) {
            return new Hc4Authentication[0];
        }

        // If already HC4 Hc4Authentication[], return directly
        if (value instanceof Hc4Authentication[]) {
            return (Hc4Authentication[]) value;
        }

        // If common POJO config, convert to HC4

#### 디렉터리 구조 { #directory-structure }

이제 다음과 같은 디렉터리 구조가 되어야 합니다:

```
.
├── app
│   ├── __init__.py
│   └── main.py
├── Dockerfile
└── requirements.txt
```
