从源安装Odoo：错误：找不到pg\u config可执行文件

Question

我使用的是源代码https://github.com/odoo/odoo/tree/aa0554d224337e1d966479a351a3ed059d297765

在Windows 10上，Python版本

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

我发现了错误

    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>).

如何修复？你知道吗

Answer 1

• 从Windows Source Install

  Warning

  Some dependencies cannot be installed through pip and require to be installed manually. In particular:

  • psycopg must be installed with this installer.
  • wkhtmltopdf must be installed in version 0.12.5 for it to support headers and footers. See our wiki for more details on the various versions.

• 如错误消息所示：

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

• python3.8的psycopg2包已经发布，您可以 用pip安装：

  pip install psycopg2  
  

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