Question

- 手上的问题 -

我在FreeNAS 9.10.2服务器上的BSD监狱中运行Odoo 10.0。尝试安装POS应用程序时，我收到带有以下回溯报告的Odoo服务器错误：

- 我的评估 -

然而，引起我注意的是接近尾迹的结尾;一个ParseError。在ParseError的细节中，它正在解析的元素在它正在解析的文件中有一个额外的属性。也就是说，它正在解析<xpath expr="...'categ_id']">'，但正在解析的文件包含<xpath expr="...'categ_id']" position="after">？

- 采取措施 -

我在尝试再次安装POS应用之前，通过从position="after"表达式中删除xpath属性来编辑有问题的xml文件。不幸的是，结果是一样的。

- 下一步 -

我可以采取哪些其他措施来解决这种情况？

- 编辑＃1 - 采取进一步措施 - 我尝试在同一个Odoo服务器上托管的另一个数据库上安装该应用程序，并且安装时该数据库没有任何问题。尝试在我尝试的第一个数据库上安装POS应用程序时，我仍遇到服务器错误。

- 编辑＃2 - 成功！ - 我采取的步骤通过评论者的有用提示解决了这个问题。

包含使用Odoo数据库管理的资产的备份数据库
在单独的本地计算机上安装postgreSQL和Odoo Server
将备份还原到本地Odoo安装（无论出于何种原因，“联系人”视图都会产生错误，但我忽略了它并继续运行）
已成功安装POS模块
使用Odoo数据库管理备份本地数据库，包括资产
将备份恢复到服务器Odoo安装
选中的联系人视图。没有错误。安装和卸载模块功能已恢复。

成功！

我仍然不确定是什么原因引起了这个问题。即使恢复旧备份也不允许我安装POS模块或任何模块。然而，现在;我可以。

安装POS插件时出现Odoo 10服务器错误
