Question

此问题出现在paramiko v2（2.4.2）中，而不是出现在paramiko v1（1.18.5）中。

密钥存储在known_hosts文件中。

我正在使用以下代码

import paramiko

ssh_client = paramiko.SSHClient()
ssh_client.load_system_host_keys()
ssh_client.connect(hostname='hostname', username='user', password='pass')

load_system_host_keys（）失败，并且我得到此回溯：

Answer 1

解决方案是enum模块的问题。加密使用enum34。我有自己的实现要在与我的代码相同的程序包中的“ enum.py”文件中进行枚举。密码学尝试使用此模块代替enum34。将我的“ enum.py”文件扩孔到其他东西就解决了。

在这里阅读： python's cryptography throwing AttributeError: 'int' object has no attribute 'value'

python的paramiko load_system_host_keys（）引发AttributeError：“ int”对象没有属性“ value”（加密）
