我在DigitalOcean上运行Ubuntu 18.04 Droplet，需要设置它们之间的文件传输。
Pysftp / Paramiko库非常适合这项工作，但是在建立连接时遇到了麻烦。从桌面使用相同的代码连接效果很好。
cnopts = pysftp.CnOpts()
cnopts.hostkeys = None
with pysftp.Connection(host='ip adress', username='username',
password='pass', cnopts=cnopts) as sftp:
初始化连接时的错误消息是：

key = ec.EllipticCurvePublicKey.from_encoded_point(
AttributeError: type object 'EllipticCurvePublicKey' has no attribute 'from_encoded_point'
最佳答案
截至目前，升级到Paramiko的最新版本– 2.6。
这很可能是与以下问题相同的问题：

强制性警告：请勿设置cnopts.hostkeys = None，除非您不关心安全性。有关正确的解决方案，请参见Verify host key with pysftp。
