应该已经修复了。我将这一行替换为\n\njs\nconst topicController = getOwner(this).lookup(\"controller:topic\");\n\n用这个\n\njs\nconst container = Discourse.__container__;\nconst topicController = container.lookup('controller:topic');\n\n\n遵循这里的示例代码 https://meta.discourse.org/t/get-category-name-using-js/177110/2\n\n很高兴您觉得它有用！
