This is a header/linker mismatch between the custom OpenSSL you've installed and the one that comes with your CentOS. Linking against custom OpenSSL can be very challenging on linux and is outside the scope of support we can provide here. We do have some information to help, but it's still difficult to get right: https://cryptography.io/en/latest/installation/#using-your-own-openssl-on-linux

Hi, @pgbidkar . I got the same error, how did you fix it? : )

[pgbidkar]

Hi @lxw0109 You tried installing $sudo yum install gcc libffi-devel python-devel openssl-devel?

Thanks

[lxw0109]

@pgbidkar Thank you. In my situation, it's still not working after installing the above packages(My fault, this is because of my outdated software sources, please read on).
When I read this page, I think maybe I have installed some packages with outdated version. So I ran the following commands:

$ sudo apt-get update
$ sudo apt-get upgrade --fix-missing

It works.
I think if I installed the required version of packages you suggested at the beginning, it might be working. Thank you.
