問題摘要
我有一個新的 rails 7 應用程式，它使用importmap-railsgem 來管理 javascript 前端庫。
我正在嘗試使用 Semantic-UI 庫，但是 Semantic-UI javascript 無法識別 jQuery 的依賴關系。
我無法通過 importmap 固定 Semantic-UI 庫，所以我importmap.rb手動添加了這個庫。這是我正在使用的語意.min.js 的 CDN 鏈接。
以下錯誤訊息出現在 Chrome Web 工具的控制臺中，并且我在頁面上驗證 javascript 的可折疊手風琴不起作用。
Uncaught ReferenceError: jQuery is not defined
at semantic.min.js:11:6043
(anonymous) @ semantic.min.js:11
中參考的行semantic.min.js如下所示
(jQuery,window,document)
嘗試修復
我認為 Semantic-UI 和 jQuery 匯入發生的順序可能是問題（根據許多其他Stack Overflow 問題和Github 問題）。
但是，我在 Semantic-UI 匯入之前進行了 jQuery 匯入。
如果我注釋掉 Semantic-UI 匯入，我可以毫無問題地使用 jQuery。
我已經切換了檔案preload上的變數，importmap.rb 以查看 Semantic-UI 是否也被加載得太快。
我嘗試將 jQuery 匯入重命名為$and jQuery，但最終都沒有被識別。
我的直覺說 Semantic-UI 在 jQuery 設定為全域變數之前加載，但我不確定它如何與新的 importmap 功能和資產管道一起作業。

uj5u.com熱心網友回復：
我通過手動更新importmap.rb從原始bin/importmap pin jquery指向的源中固定的 jquery 源解決了這個問題：
https://ga.jspm.io/npm:[email protected]/dist/jquery.js
現在成為
https://code.jquery.com/jquery-3.6.0.min.js
此外，我添加了一些 jquery 代碼以application.js在加載檔案時運行（根據Semantic-UI 網站上的檔案
$(document).ready(function(){
$('.ui.accordion').accordion()});
