How to install psycopg2, fro linux, Fedora - postgresql

Question

There are errors when I try to install psycopg2
pip install psycopg2
I don't know whether I have pg_config or not. I tried these to find out where is pg_config, psql. but I don't understand how pg_config is not in the system when I have installed PostgreSQL(11.4). And if it is there in the system how to set the PATH so that psycopg2 installation is possible.
(myvenv) [jpsofficedev#localhost djangogirls]$ postgres --version
postgres (PostgreSQL) 11.4
(myvenv) [jpsofficedev#localhost djangogirls]$ echo $PATH
/home/jpsofficedev/Documents/coding_for_girls/djangogirls/myvenv/bin:/home/jpsofficedev/.local/bin:/home/jpsofficedev/bin:/usr/share/Modules/bin:/usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin:/var/lib/snapd/snap/bin:/Library/PostgreSQL/11.4/bin
(myvenv) [jpsofficedev#localhost djangogirls]$ which psql
/usr/bin/psql
(myvenv) [jpsofficedev#localhost djangogirls]$ which pg_config
/usr/bin/which: no pg_config in (/home/jpsofficedev/Documents/coding_for_girls/djangogirls/myvenv/bin:/home/jpsofficedev/.local/bin:/home/jpsofficedev/bin:/usr/share/Modules/bin:/usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin:/var/lib/snapd/snap/bin:/Library/PostgreSQL/11.4/bin)

Error: pg_config executable not found.
pg_config is required to build psycopg2 from source. 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'.
If you prefer to avoid building psycopg2 from source, please install the PyPI
'psycopg2-binary' package instead.
For further information please check the 'doc/src/install.rst' file (also at
<http://initd.org/psycopg/docs/install.html>).
