Question

我正在尝试将Plone 3.3.5安装迁移到4.0.7。

在迁移之前，决定删除Plone4Artists日历。

我们遵循此处提出的程序http://plone.org/documentation/kb/cleaning-p4a，将其应用于以下界面：

from p4a.calendar.interfaces import ICalendarEnhanced
from p4a.calendar.interfaces import IPossibleCalendar
from p4a.calendar.interfaces import ICalendarConfig
from p4a.calendar.interfaces import IEventProvider
from p4a.calendar.interfaces import IEvent
from p4a.calendar.interfaces import IBasicCalendarSupport
from p4a.calendar.interfaces import ICalendarSupport

显然，它有效（除了IPossibleCalendar接口，我得到了“只能删除直接提供的接口。”消息）。为了消除这种情况，我们卸载了产品（遵循here的好建议）

现在，在将Data.fs从3.3.5移动到4.0.7安装，并尝试在/ Plone / @@ plone-upgrade上激活迁移后，我得到以下回溯：

PicklingError: Can't pickle <class 'p4a.calendar.interfaces.ICalendarSupport'>: import of module p4a.calendar.interfaces failed

请注意，这是一个测试运行：它是一个虚假和干净的Data.fs，唯一涉及的产品是P4A.Calendar，它已安装（并在将Data.fs移动到4.0.7安装之前卸载）仅在3.3.5扩建时。

我还尝试遵循here的建议，而Plone对象的SiteManager没有任何带有“p4a”字符串的适配器或订阅者。全局SiteManager中的 dict 属性也不会报告任何“p4a”字符串的出现。

任何人都可以对此有所了解吗？我应该在哪里寻找Data.fs中的“p4a.calendar.interfaces.ICalendarSupport”？

从3.3.5迁移到4.0.7时由p4a.calendar.interfaces.ICalendarSupport引起的PicklingError
