这个问题在这里已经有了答案:HowtosilenceEllipticCurvePublicNumbers.encode_pointCryptographyDeprecationWarningwhenusingParamikoinPython(2个答案)关闭3年前。在进行简单的SSH连接时，我不断收到以下弃用警告:2019-03-0402:21:14[transport]INFO:Connected(version2.0,clientOpenSSH_7.4)/usr/local/lib/python2.7/site-packages/paramiko/kex_ecdh_nist.py:3

事情进展顺利，直到我的一个项目开始在每个地方打印它，在每次执行的顶部，至少打印一次:local/lib/python2.7/site-packages/cryptography/hazmat/primitives/constant_time.py:26:CryptographyDeprecationWarning:SupportforyourPythonversionisdeprecated.Thenextversionofcryptographywillremovesupport.Pleaseupgradetoa2.7.xreleasethatsupportshmac.compare

pycharmanaconda环境升级python后就一直警告~/.local/lib/python3.10/site-packages/paramiko/transport.py:236:CryptographyDeprecationWarning:Blowfishhasbeendeprecated "class":algorithms.Blowfish,这在Paramiko2.11.0中已修复解决办法：您可以通过以下方式更新paramiko：pipinstall--upgradeparamiko.完美修复

原因:此时版本python3.6；Cryptography37.04 解决办法:降版本，降Cryptography至3.4.8，就可以正常运行；               或者升级python3.9，高版本的python可以兼容这些冲突先查看已经安装的Cryptography版本pipshow Cryptography卸载pipuninstall cryptography查看有哪些版本pipinstall cryptography== 安装较低版本pipinstall cryptography==3.4.8
