paramiko 'module' 没有属性 'new'

Question

我使用此代码 FTP 图像已经一年多了，没有任何改变，然后我在尝试 FTP 时突然出错。我试过重启/等。代码是（我已经用'...'替换了地址）：

with pysftp.Connection('...', username='...', password='...') as sftp:
    sftp.cd('...')
    sftp.put(figure1)

使用 paramiko v1.16 和 v2.1.2 时出现以下错误（尝试更新版本，但没有解决）：

    ERROR:paramiko.transport:Unknown exception: 'module' object has no attribute 'new'

    AttributeError: 'module' object has no attribute 'new' 

有谁知道如何解决这个问题？我已经确认我的 SFTP un/pw 是正确的，可以上网，等等。

需要加密更新；错误现在消失了，FTP 正常。
