Answer 1

Pycharm has/had an issue with installing psycopg2

Try deleting that temporary directory first

Then try installing it using pip

pip install psycopg2==2.4.5

Answer 2

The other solutions did not work for me. When I tried to install psycopg2 using commands it gave a lot of errors.
I successfully installed it by:
File -> Settings -> Project Interpreter -> Clicked + -> Search , then added the psycopg2 package there.
