я использую aws linux, который по умолчанию python равен 2.7. Я установил 3.7 и изменил псевдоним python = python3 сейчас, когда я python -V получаю: Python 3.7.6. я запускаю pip3, устанавливаю psycopg2
и получаю:
pip3 install psycopg2
Defaulting to user installation because normal site-packages is not writeable

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
<https://www.psycopg.org/docs/install.html>).

также установил клиент postgresql10, используя
sudo amazon-linux-extras install postgresql10
почему я все еще получаю сообщение об ошибке?
