我試圖建立到sftp服務器的測試連接。 （如Python Pysftp Error所示）。我通過終端建立到服務器的第一個連接，從服務器獲得密鑰。這工作完美無瑕。但是，如果我運行python腳本：使用pysftp設置到服務器的測試連接
import pysftp
sftp = pysftp.Connection('test.rebex.net', username='demo', password='password')
data = s.listdir()
sftp.close()
for i in data:
print(i)
我收到以下錯誤信息：

我檢查了/etc/ld.so.conf.d/libc.conf文件有一個查看/ usr/local/lib的搜索路徑。在上述路徑中，我可以找到libssl.so.1.1文件。有沒有人有關於如何解釋錯誤信息的建議或知道我出錯的地方？非常感謝。
