问题描述

我正在尝试pip install psycopg2==2.7.*在我的 PyCharm 终端上运行该程序包，以便我可以部署我的站点，但我收到了下面显示的消息

    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>).

解决方案

如果你在 Linux 上，你需要安装 PostgreSQL 来运行你的数据库，然后将客户端连接到你的 PostgreSQL 数据库，你需要其他包，比如libpq-dev，libpq5。

您可以使用以下命令安装上述软件包。

sudo apt-get install postgresql
sudo apt-get install libpq5
sudo apt-get install libpq-dev
