我正在嘗試在 Windows 中安裝 psycopg2 並出現錯誤

Question

我正在執行以下命令，它對 psycopg2-binary 顯示相同

(demo) C:\Users\Lenovo\Desktop\Django>pip install psycopg2
Collecting psycopg2

    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>).

也許這會有所幫助（pip install psycopg2）。 據我了解，有一種答案（ 找不到 pg_config 可執行文件）。也許我錯了（99% 的保證，我錯了，只是因為我是編程新手）。
