Upgrade Plone 3.3.6 to either Plone 4.3.7 or Plone 5 (Error: 'tuple' object has no attribute 'remove')
Upgrade Plone 3.3.6 to either Plone 4.3.7 or Plone 5 (Error: 'tuple' object has no attribute 'remove')
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，没有安装附加产品（vanilla Plone、vanilla template 等）确实安装了 CacheFu，但经过一些早期的安装明显的错误，我在升级之前将其删除。我只是将 var/filestorage（Data.fs 等）的内容从 v3 站点复制到 v4 站点，然后重新构建 运行。
在Plone 4.3.7中，运行设置UPGRADE选项时，看到很多成功activity，然后在最下面出现如下错误：
Upgrade aborted. Error:

如果我跳过 Plone 4.x 并直接跳到 Plone 5.0，我什至无法 运行 UPGRADE 功能，并且只会在控制台上得到以下错误跟踪：
