Question

使用Plone 4.2.5的网站升级为Plone 4.3.4。

执行签出对象时，会显示以下错误：

PicklingError: Can't pickle <class 'plone.app.kss.interfaces.IPortalObject'>: import of module plone.app.kss.interfaces failed

目录中没有对象提供plone.app.kss.interfaces.IPortalObject。

有什么想法吗？

在迁移之前，您应该始终阅读Plone升级指南：

https://plone.org/documentation/manual/upgrade-guide/version/upgrading-plone-4.2-to-4.3/referencemanual-all-pages

Plone.app.kss不再随Plone 4.3.x一起提供。您必须将它重新添加到buildout.cfg：

eggs =
    ...
    plone.app.kss

虽然，我建议您在升级后清理ZODB。否则你会遇到问题，因为plone.app.kss没有维护。

升级到Plone 4.3后的PicklingError
