我似乎遇到了问题。我需要在python中使用pip-install db_utils来安装db_util，但要做到这一点，我需要首先使用pip-innstall psycopg2(而不是二进制(。我犯了一些错误，我似乎无法消除。我使用mac并收到以下消息：
1.pip安装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 ...

If you prefer to avoid building psycopg2 from source, please install the PyPI
'psycopg2-binary' package instead.

感谢您抽出时间
对于我的情况，我遇到了类似的错误，在运行命令时必须遵循说明
brew link openssl
我希望这对有帮助
您可以安装它的二进制文件：
pip install psycopg2-binary
