您好，
首先，这是我发布到官方 algolia-discourse 论坛的帖子副本。根据 Discourse-Support 的指示，我现在可以将其发布在这里，因此这是一个复制的消息。
我想设置我们的 Discourse 与 Algolia 集成，但它没有按照 GitHub 上的描述工作。我使用的是最新版本：3.1.0.beta1。
为了进行首次初始化，我使用以下命令打开我的 discourse-docker：
./launcher enter app
之后，我尝试了不同的命令（bundle exec rails 或仅 rails，还有 rake），但所有结果都是：
root@rbx-communtity-service-app:/var/www/discourse# LOAD_PLUGINS=1 rails algolia:initialize
rails aborted!
Don’t know how to build task ‘algolia:initialize’ (See the list of available tasks withrails --tasks)
Did you mean? algolia:reindex
当我只运行 algolia:reindex 时，我得到以下结果：
root@rbx-communtity-service-app:/var/www/discourse# LOAD_PLUGINS=1 rake algolia:reindex

有什么想法可能是什么问题吗？
提前感谢！

This fix is already inside my discourse-version. Same issue as before.
显然，我们都遇到了一个问题，即至少有一个帖子是孤立的，缺少主题 ID，这导致 rake 任务出错。建议是找到并删除这些孤立帖子，然后 rake reindex 就可以顺利运行了。
我可以确认，删除
