Odoo 14：销售点安装错误

Question

我使用默认设置在Docker中安装了running Odoo 14，没有任何其他自定义。在过去的几天里，我一直在尝试从Odoo内部安装销售点模块，但都没有成功——每次我都会遇到下面的错误。

有谁能帮我找出问题所在，让PoS机工作吗？

谢谢你！

    The above exception was the direct cause of the following exception:

如果你想提高成功的几率，不要尝试从其他版本或第三方加载任何模块，并尝试坚持基本功能，或尝试使用其他公司支持的旧版本或打包，例如https://github.com/Elico-Corp/odoo-docker或叉子，例如https://hub.docker.com/r/flectrahq/flectra/

看起来您使用的是销售点插件的不兼容版本。

你需要从Odoo高于平均水平的留档开始：https://www.odoo.com/documentation/14.0/

鉴于你正在处理一个模块，你需要投入一些时间https://www.odoo.com/documentation/14.0/howtos/backend.html

如果您想进一步了解Python，请给自己几个月的时间，从以下内容开始：https://www.udemy.com/course/the-complete-python-course/然后继续https://subscription.packtpub.com/search?query=working与奥多11

要移动数据库，只需转到数据库管理器：http://odoo:8069/web/database/manager#action=database_manager然后从那里导出数据库，然后通过新实例上的相同URL导入。

除了任何软件有时会带来突破性的变化，以及任何ERP的内部都需要高水平的技术专业知识之外，由于“突破性变化”在其激励使用托管服务的策略中发挥作用，特别是粗心的Odoo员工，Odoo CE似乎更为不利，这是他们的主要收入模式。（他们在非GPL许可证下重写模块的努力也证明了这一点。）

他们显然对推动开源的人性缺乏信心。让我们不断激励他们分享、帮助和开放。开源不仅仅是一种廉价的营销伎俩：开源的力量来自信任和无条件的给予，这推动了一个任何数量的公司都可以处理的更大的市场。
