从源安装Odoo：错误：找不到pg_config可执行文件

Question

我正在使用源代码https://github.com/odoo/odoo/tree/aa0554d224337e1d966479a351a3ed059d297765

在Windows 10（Python版）上

Python 3.8.0 (tags/v3.8.0:fa919fd, Oct 14 2019, 19:21:23) [MSC v.1916 32 bit (Intel)] on win32

我发现错误

    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.

    For further information please check the 'doc/src/install.rst' file (also at
    <http://initd.org/psycopg/docs/install.html>).

如何解决？

Answer 1

• 来自Windows Source Install

    

  警告   

  某些依赖项无法通过pip安装，需要手动安装。   特别是：

  • psycopg必须与   this installer。
  • wkhtmltopdf必须安装在0.12.5版中   它支持页眉和页脚。看我们的   Wiki上的更多详细信息    各种版本。

• 错误消息提示您：

    

  如果您不想避免从源代码构建psycopg2，请安装PyPI       而是使用“ psycopg2-binary”软件包。

• 已发布Python 3.8的psycopg2软件包，您可以 用pip安装它：

  pip install psycopg2  
  

• 如果要从源代码安装psycopg2，请参阅official docs。
