windwos raise OSError: [Errno 9] Bad file descriptor

the file ./utils/socket.py line 31 hava code os.read(socket.fileno(), n) but windows not support

my call container.exec_run("xxx", socket=False) raise:

I met same error, is there a workaround ?

rewrite read function in utils\socket.py

def read(socket, n=4096):
    """
    Reads at most n bytes from socket
    """

    recoverable_errors = (errno.EINTR, errno.EDEADLK, errno.EWOULDBLOCK)

    if six.PY3 and not isinstance(socket, NpipeSocket):
        select.select([socket], [], [])

    try:
        if hasattr(socket, 'recv'):
            return socket.recv(n)
        # fix OSError
        try:
            return os.read(socket.fileno(), n)
        except OSError:
