Pycharm安装psycopg2失败

Question

I'm trying to install psycopg2 to use a postgresql db in the backend of my django project, but every time I run the pip install psycopg2 command I get an error saying:

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'.

I have added the \bin\ folder containing the file to my path, I've ran the pip install psycopg2-binary command as well, and I've uninstalled and reinstalled posgresql on my computer, I've also ran the python setup.py build_ext command mentioned in the error message, and this error still pops up. I'm operating on a windows 10 os and using posgresql 13.1. Any suggestions?

EDIT: This is the error I'm getting in my terminal:

Error in PyCharm terminal

You've probably done this already, but the steps should be:

1. Install PostgreSQL.
2. Add the PostgreSQL bin/ folder to your path.
3. Restart your command line to make sure your path is set correctly.
4. Run pip install psycopg2

I have a clean install of Windows 10 over here and it seems to work for me. Running pip install psycopg2-binary should definitely work (even without PostgreSQL) because that doesn't compile anything, so I'm interested if you also have errors there.
