收到错误-AttributeError：运行subprocess.run（[[ls“，” -l“]）时'module'对象没有属性'run'

该

subprocess.run()

但是，向后移植很容易：

def run(*popenargs, **kwargs):    input = kwargs.pop("input", None)    check = kwargs.pop("handle", False)    if input is not None:        if 'stdin' in kwargs: raise ValueError('stdin and input arguments may not both be used.')        kwargs['stdin'] = subprocess.PIPE    process = subprocess.Popen(*popenargs, **kwargs)    try:        stdout, stderr = process.communicate(input)    except:        process.kill()        process.wait()        raise    retpre = process.poll()    if check and retpre:        raise subprocess.CalledProcessError( retpre, process.args, output=stdout, stderr=stderr)    return retpre, stdout, stderr

没有为超时的支持，并为完成过程信息没有自定义类，所以我只能返回

retpre

stdout

stderr
