Stellen Sie sicher, dass Sie eine [virtuelle Umgebung](../virtual-environments.md){.internal-link target=_blank} erstellen, sie aktivieren und dann das Paket installieren, zum Beispiel:

```console
$ pip install python-multipart

## 不使用 Pydantic

До FastAPI 0.106.0 вызывать исключения после `yield` было невозможно: код после `yield` в зависимостях выполнялся уже после отправки ответа, поэтому [Обработчики исключений](../tutorial/handling-errors.md#install-custom-exception-handlers){.internal-link target=_blank} к тому моменту уже отработали.

이 명령어는 이후에 실행될 명령어에서 사용될 [환경 변수](environment-variables.md){.internal-link target=_blank} 몇 개를 생성하거나 수정합니다.

이 변수들 중 하나가 바로 `PATH` 변수입니다.
