python - 无法在 Windows 上安装 psycopg2 2.8.6

问题描述

我无法在我的 Windows 上安装 psycopg2 2.8.6 或 psycopg2-binary。安装时出现以下错误。

PS C:\Users\UserName\Desktop\PythonUnitTestFW> pip install psycopg2-binary 收集 psycopg2-binary 使用缓存的 psycopg2-binary-2.8.6.tar.gz (384 kB) 错误：命令错误退出状态 1：命令： 'c:\python39\python.exe' -c '导入系统，setuptools，tokenize；sys.argv[0] = '"'"'C:\Users\UserName\AppData\Local\Temp\pip-install-e12d1gsx\psycopg2-binary\setup.py'"'"'; file ='"'"'C:\Users\UserName\AppData\Local\Temp\pip-install-e12d1gsx\psycopg2-binary\setup.py'"'"';f=getattr(tokenize, '"'"' open'"'"', open)( file );code=f.read().replace('"'"'\r\n'"'"', '"'"'\n'"'", '"'"'exec'"'"'))' egg_info --egg-base 'C:\Users\UserName\AppData\Local\Temp\pip-pip-egg-info-bs6x9b8l' cwd: C:\ Users\UserName\AppData\Local\Temp\pip-install-e12d1gsx\psycopg2-binary

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>).

----------------------------------------

错误：命令出错，退出状态为 1：python setup.py egg_info 检查日志以获取完整的命令输出。
