使用子过程处理Pyenv命令

Question

IM正在使用逻辑来自动使用SubProcess创建Pyenv Virtualenv的过程。 不幸的是，试图一次运行多个pyenv shell命令

def subprocess_cmd(command):
    
    process = subprocess.Popen(command,stdout=subprocess.PIPE, shell=True)
    proc_stdout = process.communicate()[0].strip()
    process.poll()
    print (proc_stdout)

def run_cmd():
    
    python_version = "3.9.6"
    dirName = "D:/python_venv" + '/' + str(python_version)
    os.makedirs(dirName, exist_ok=True)

    try:
       subprocess_cmd('pyenv install -l,pyenv install 3.9.0,pyenv local 3.9.6,python -m venv .venv')   
    except subprocess.CalledProcessError as exception:
        return None

run_cmd()

，它没有成功。投掷以下错误

:: [Info] ::  Mirror: https://www.python.org/ftp/python
pyenv-install: definition not found: -l;

See all available versions with `pyenv install --list'.
