Error: pg_config executable not found when install psycopg2 in CentOS 7.9

I am install psycopg2 in the CentOS 7.9 using this command:

pip3.9 install psycopg2

but shows error like this:

ERROR: Command errored out with exit status 1:

Please add the directory containing pg_config to the PATH
or specify the full executable path with the option:

    python setup.py build_ext --pg-config /path/to/pg_config build ...

or with the pg_config option in 'setup.cfg'.
----------------------------------------

I have already install postgresql13-devel using command dnf install postgresql13-devel -y and install successs. why still could not install the psycopg2?

2023 on Mac M1 when trying to setup a Postgres instance for my Django app. This is how I installed it.

python3 -m pip install psycopg2-binary

add the pg_config path to the system execute search path, for example, my PostgreSQL was installed in the path /opt/pg13, so export the path like this would fix this problem:

export PATH=/opt/pg13/bin:$PATH
