Question

我正在执行以下命令，并且对于psycopg2-binary显示相同的命令

(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>).

也许这会有所帮助（pip install psycopg2）。据我了解，有一个答案（pg_config executable not found）。也许我错了（99％的保证，我错了，只是因为我是编程新手）。

我正在尝试在Windows中安装psycopg2并出现错误
