我一直在尝试为我的 django 项目安装 psycopg2-binary，但到目前为止没有任何效果。它不断要求pg_config文件，据我所知，只有在构建 psycopg2 时才需要该文件。那么，这里发生了什么？
Collecting 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>).

当然，pip 是最新版本，我已经指定了pip install psycopg2-binary.
我的Mac的架构是arm64。
任何帮助，将不胜感激。谢谢
我在网上找到了这个，它对我有用：
❯ brew install postgresql
如果您打开一个新的终端选项卡，您将看到 pg_config 可用
❯ export CPPFLAGS="-I/opt/homebrew/opt/[email protected] /cdn-cgi/l/email-protection/include"
❯ export LDFLAGS="-L/opt/homebrew/opt/[email protected] /cdn-cgi/l/email-protection/lib -L${HOME}/.pyenv/versions/3.8.10/lib"
❯ python -V
Python 3.8.10
❯ pip install psycopg2-binary==2.8.6
