Odoo 数据库导出错误

Question

我在 Windows 10 中使用 Odoo 11，这使其不稳定，所以我决定从 linux 启动它。

问题是当我尝试从数据库管理器中导出数据库时，它给了我500 Internal Server Error。知道出了什么问题吗？

这是日志：

2018-07-15 07:54:29,292 6920 错误 odoo2 odoo.addons.web.controllers.main: Database.backup 回溯（最近一次通话最后）： 文件“C:\Program Files\Odoo 11.0\server\odoo\tools\misc.py”，第 94 行，在 find_pg_tool 返回哪个（名称，路径=路径） 文件“C:\Program Files\Odoo 11.0\server\odoo\tools\which.py​​”，第 144 行，其中 raise IOError(ENOENT, '%s not found' % (mode & X_OK and 'command' or 'file'), file) FileNotFoundError: [Errno 2] 命令未找到: 'pg_dump'

在处理上述异常的过程中，又发生了一个异常：

Answer 1

您的错误消息中有趣的部分是：

command not found: 'pg_dump'

这表示您需要将PostgreSQL的bin目录（默认：C:\Program Files\PostgreSQL\9.4\bin）添加到您的PATH中。 作为参考，请参阅源安装/准备部分中的“在 Windows 上”段落：https://www.odoo.com/documentation/11.0/setup/install.html#id3 请注意，如果您将 Odoo 作为 Windows 服务运行，则需要重新启动 Windows，以便进程在系统环境中获取此更改变量。

截断的另一条日志包含另外两条错误消息。 第一条消息是

psycopg2.InterfaceError: connection already closed

这可能是由于转储/导出失败后的下一条语句造成的。或者，这可能是您所指的“不稳定”的另一个症状。通常，这种错误只会在长时间运行的事务从数据库端被终止（例如超时）然后仍然从客户端使用时发生。

要进一步检查这一点，请发布另一个问题，其中包含更多详细信息，例如：观察到的错误消息、postgres 配置和 Odoo 配置文件。

第二条消息是

poplib.error_proto: b'-ERR [AUTH] Authentication failed.'

来自odoo\addons\fetchmail\models\fetchmail.py。这表明您的 Odoo 服务器的电子邮件设置中的用户名/密码设置存在问题。这与稳定性或导出数据库的能力无关。
