Answer 1

Tested with Python 3:

sudo yum groupinstall "Development Tools"
sudo yum install python3-devel
sudo yum install postgresql-libs
sudo yum install postgresql-devel
[sudo] pip install psycopg2

Answer 2

你似乎缺少一个

sudo yum install postgresql-libs

Answer 3

http://mirror.centos.org/centos/7/os/x86_64/Packages/

Test this

yum install python-psycopg2

Answer 4

The installation of postgresql-libs does not help, it actually needs a valid postgresql client. Therefore installing the devel package for CentOS 7 solves it (if it's not an overkill for you).

yum install postgresql-devel

This started happening due to the fact that the pip package stopped shipping with postgresql client binaries, which makes sense since you might want to use a different version in certain scenarios.
