'SSHClient' 对象在 ssh.connect() 上没有属性 'known_hosts'

Question

我正在尝试使用以下代码连接 ssh 服务器

ssh = paramiko.SSHClient()
ssh.load_system_host_keys()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.load_host_keys(os.path.expanduser(os.path.join("~", ".ssh", "known_hosts"))
ssh.connect("10.1.3.2", username = "root")

但我收到以下错误消息

Exception during testMethod !!
Traceback (most recent call last):
  File "/usr/local/lib/python2.7/dist-packages/Qb/QbUnittest/QbUnittest.py", line 624, in __call__

    if self.known_hosts is not None:
AttributeError: 'SSHClient' object has no attribute 'known_hosts'

有人可以帮助我了解问题所在吗？

Answer 1

这是一个 known bug，修复已发布到版本 1.12.1；你似乎在使用 1.12.0。尝试升级到最新版本：

pip install --upgrade paramiko

Answer 2

快速修复：

ssh = paramiko.SSHClient()
ssh.known_hosts = None
...
...

bug 已修复 here。
