气流泊坞窗操作员内部服务器错误“ b'安装被拒绝：EOF'”MacOS

如何解决气流泊坞窗操作员内部服务器错误“ b'安装被拒绝：EOF'”MacOS

我正在尝试在气流管道上使用docker运算符。这是我正在使用的代码：

from airflow import DAG
from airflow.operators.bash_operator import BashOperator
from datetime import datetime,timedelta
from airflow.operators.docker_operator import DockerOperator

default_args = {
        'owner'                 : 'airflow','description'           : 'Use of the DockerOperator','depend_on_past'        : False,'start_date'            : datetime(2018,1,3),'email_on_failure'      : False,'email_on_retry'        : False,'retries'               : 1,'retry_delay'           : timedelta(minutes=5)
}

with DAG('docker_dag',default_args=default_args,schedule_interval="5 * * * *",catchup=False) as dag:
        t1 = BashOperator(
                task_id='print_current_date',bash_command='date'
        )

        t2 = DockerOperator(
                task_id='docker_command',image='alpine:3.7',api_version='auto',auto_remove=True,command="/bin/sleep 30",docker_url="unix://var/run/docker.sock",network_mode="bridge"
        )

        t3 = BashOperator(
                task_id='print_hello',bash_command='echo "hello world"'
        )

        t1 >> t2 >> t3

我使用气流UI运行DAG，但是在docker_command任务中出现此错误：

更新：本练习是在Mac上完成的，但是我尝试在Linux OS（Ubuntu 18.04发行版）上执行相同的操作，并且一切正常。因此，恐怕这与我在macOS上的配置或计算机上的权限有关。

在Mac上，我拥有Catalina版本10.15.5。

您知道为什么我会收到该错误吗？
