[英]How to install psycopg2 on Python 3.9 on Windows?
我一直在尝试安装 psycopg2 ( pip install psycopg2
),但我不断收到此错误。
我也尝试过: pip install psycopg2-binary
但我遇到了同样的错误。
这是错误消息:
ERROR: Command errored out with exit status 1:

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>).

如何解决?
下面将为 Windows 安装预构建的二进制文件。 它在 3.9 上对我有用。 您可以在安装 psycopg2 后卸载 pipwin。
pip install pipwin
pipwin install psycopg2
安装 psycopg2 后可选:
pip uninstall pipwin
如果你使用 linux
您需要确保安装轮模型并尝试使用sudo ./venv/bin/python -m pip install wheel
之后安装 psycopg2 和 psycopg2-binary
sudo ./venv/bin/python -m pip install psycopg2
sudo ./venv/bin/python -m pip install psycopg-binary
