centos8 64位的系统，域名解析也是好的，请问这是真么问题呀？

[hijk]

pip依赖，或者服务器环境问题
请这样操作：pip3 uninstall cryptography; cd /usr/lib64/python3.6/dist-packages; rm -r cryptoggraphy cryptography-2.1.4.egg-info; pip3 install cryptography
然后再试试

[hikuly]

好的，我正在重装服务器系统，用centos7试试看看

[hijk]

嗯，按理说centos没有这个问题，ubuntu才可能有

[hikuly]

嗯，重装系统后搞定了，谢谢！
