ОШИБКА: не удалось построить колесо для psycopg2. ⇐ Python

It appears you are missing some prerequisite to build the package from source.

You may install a binary package by installing 'psycopg2-binary' from PyPI.
If you want to install psycopg2 from source, please install the packages
required for the build and try again.

For further information please check the 'doc/src/install.rst' file (also at
).

Я пробовал выполнить pip install psycopg2-binary, но он у меня уже установлен. Я также пробовал задавать уже заданные вопросы, но ничего не помогло. Заранее спасибо
