최신 버전의 Python을 사용하기 위해`venv '로 Python 가상 환경을 업데이트하려면 어떻게해야합니까?

나는 당신이 찾고있는 것이 --upgrade매개 변수 라고 생각합니다 .

python -m venv --help
usage: venv [-h] [--system-site-packages] [--symlinks | --copies] [--clear]
            [--upgrade] [--without-pip] [--prompt PROMPT]
            ENV_DIR [ENV_DIR ...]

Creates virtual Python environments in one or more target directories.

positional arguments:
  ENV_DIR               A directory to create the environment in.

optional arguments:
  -h, --help            show this help message and exit
  --system-site-packages
                        Give the virtual environment access to the system
                        site-packages dir.
  --symlinks            Try to use symlinks rather than copies, when symlinks
                        are not the default for the platform.
  --copies              Try to use copies rather than symlinks, even when
                        symlinks are the default for the platform.
  --clear               Delete the contents of the environment directory if it
                        already exists, before environment creation.
  --upgrade             Upgrade the environment directory to use this version
                        of Python, assuming Python has been upgraded in-place.
  --without-pip         Skips installing or upgrading pip in the virtual
                        environment (pip is bootstrapped by default)
  --prompt PROMPT       Provides an alternative prompt prefix for this
                        environment.

대상 Python 버전으로 실행해야합니다. 예를 들면 다음과 같습니다.

python3.8 -m venv --upgrade <path_to_dir>

python3.8이 python 3.8.0 실행 파일의 이름이라고 가정합니다.
