我的代码:

#!/usr/bin/env python3

from paramiko.client import SSHClient, WarningPolicy

HOST_NAME = "********"
USER_NAME = "********"
PASSWD = "********"

def ssh_setup():
    client = SSHClient()
    client.load_system_host_keys()
    client.set_missing_host_key_policy(WarningPolicy)
    client.connect(HOST_NAME, 22, USER_NAME, PASSWD)
    return client

def main():
    client = ssh_setup()
    client.exec_command("DISPLAY=:0.0 notify-send \"Test\"")
    client.close()

if __name__ == "__main__":
    main()

运行时,我收到以下错误:

Traceback (most recent call last):

  File "./test", line 25, in main
    client = ssh_setup()

    client.connect(HOST_NAME, 22, USER_NAME, PASSWD)
