plone - 将 Plone 3.3.6 升级到 Plone 4.3.7 或 Plone 5(错误 : 'tuple' object has no attribute 'remove' )

Question

我正在尝试将现有站点从 Plone 3.3.6 升级到 Plone 4.3.7，然后升级到 Plone 5.0。

现有站点非常小，并且没有安装任何附加产品(vanilla Plone、vanilla 模板等)它确实安装了 CacheFu，但是在经历了一些早期明显的错误之后，我在升级之前删除了它。我只是将 var/filestorage(Data.fs 等)的内容从 v3 站点复制到 v4 站点并重新运行构建。

在 Plone 4.3.7 中，当运行 UPGRADE 选项时，我看到很多成功的事件，然后在底部出现以下错误:

    Upgrade aborted. Error:
Traceback (most recent call last):
  File "/usr/local/Plone4_migration/buildout-cache/eggs/Products.CMFPlone-4.3.7-py2.7.egg/Products/CMFPlone/MigrationTool.py", line 259, in upgrade
    step['step'].doStep(setup)
  File "/usr/local/Plone4_migration/buildout-cache/eggs/Products.GenericSetup-1.7.7-py2.7.egg/Products/GenericSetup/upgrade.py", line 160, in doStep

    value.remove('Large Plone Folder')
AttributeError: 'tuple' object has no attribute 'remove'

如果我跳过 Plone 4.x 并直接跳到 Plone 5.0，我什至无法运行升级功能，只能在控制台上得到以下错误跟踪:
