我在尝试使用paramiko ssh到EC2中的实例时遇到以下错误。 pem文件未损坏。我确实直接从我的笔记本电脑上使用密钥SSH，没有任何问题。我也试过包含参数passphrase = None，但仍然有同样的错误。我对Python很陌生，之前我从未使用过paramiko，所以我不确定我还能做些什么来排除故障。有人可以提供任何建议吗？非常感谢您的帮助。
import boto3
import paramiko
cert = paramiko.RSAKey.from_private_key_file("C:\\data\\aws-key.pem")
c = paramiko.SSHClient()
c.set_missing_host_key_policy(paramiko.AutoAddPolicy())
print "connecting..."
c.connect( hostname = "10.28.73.174", username = "ec2-user", pkey = cert,)
print "connected!!!"
stdin, stdout, stderr = ssh.exec_command('ls')
print stdout.readlines()
c.close()
connecting...
