django - 无法安装 psycopg2-binary

Question

我正在尝试在预装 Postgresql 12 的 Centos 7 上的 Django 项目的虚拟环境中安装 psycopg2-binary (pip3 install psycopg2-binary) 并出现众所周知的错误:

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.

我试图安装python3-devel postgresql-libs postgresql-server postgresql-devel postgresql-contrib，但仍然有这个错误。
pip3 install psycopg2, pip install psycopg2 - 同样的问题。
PS 问题已通过更新 pip (pip install --upgrade pip) 解决。
