ReferenceError: Composer is not defined

出现此错误是因为你的代码中未定义 Composer。查看 tags-show 路由，你会发现 Composer 是在顶部定义的。

https://github.com/discourse/discourse/blob/master/app/assets/javascripts/discourse/routes/tags-show.js.es6#L2

不过，由于你是在主题脚本标签中操作，因此无法使用 import。你需要改用 require。

因此，如果你在代码顶部添加如下内容，问题应该就能解决：

const Composer = require("discourse/models/composer");

尽管如此，我强烈建议你花些时间阅读以下内容：

Split up theme Javascript into multiple files

Complex theme javascript can be split into multiple files, to keep things nicely organised. To use this functionality, simply add files to the /javascripts folder in your theme directory. These files can not be edited from the Discourse UI, so you must use the Theme CLI or source the theme from git. Javascript files are treated exactly the same as they are in core/plugins, so you should follow the same file/folder structure. Theme files are loaded after core/plugins, so if the filenames match,…

并尝试这种创建主题的新方法。这样能更轻松地参考核心代码中的示例。
