如何卸载此模块，因为此问题会导致admin/modules/卸载页面崩溃：

我忘了提到，管理/结构/论坛给了我以下内容：

Answer 1

只需重新创建论坛词汇表，然后您应该能够卸载模块。

Answer 2

下面对它进行了修正，我怀疑这是因为在生成论坛内容而没有论坛词汇表时，Devel模块(在我的例子中)中有一些bug：

1. 在/admin/structure/分类法/add创建了一个“论坛”词汇表
2. 返回到/admin/模块/卸载不再出现错误，但论坛复选框已被禁用，并有以下消息：

以下原因阻止了论坛的卸载:要卸载论坛，首先删除所有论坛内容

1. 在内容管理admin/content?title=&type=forum&status=All&langcode=All删除所有论坛类型的内容。(我是由开发模块生成的)。
2. 现在回到Modules >卸载论坛复选框是启用和可卸载。

Answer 3

试着先检查数据库：

select * from public.node__taxonomy_forums

select * from public.taxonomy_term_revision__forum_container;

我在taxonomy_term_revision__forum_container中找到了我不知道的三个术语。一旦这些被删除，我能够成功卸载论坛。
