Question

当我在Pycharm终端pip install psycopg2中运行时，它给我这个错误Command "python setup.py egg_info" failed with error code 1 in C:\Users\...，我尝试了很多在stackoverflow上发现的问题，但仍然无法正常工作。我的pip版本是19.0.3，而我的python版本是3.8

下面的日志中还显示Error: pg_config executable not found

当我尝试安装psycopg2时的完整日志

    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
    <http://initd.org/psycopg/docs/install.html>).

Command "python setup.py egg_info" failed with error code 1 in C:\Users\xxx\AppData\Local\Temp\pip-install-ws21otxr\psycopg2\

Answer 1

使用pip安装postgres客户端将尝试从源代码进行构建和安装，该错误消息中还列出了其他依赖项。

继续做 pip安装psycopg2-binary 然后您就走了

命令“ python setup.py egg_info”失败，错误代码为1？
