Ich habe lange gesucht, warum sich mein Bootstrap-Menü nicht öffnet.
Ich habe zuerst JQuery verlinkt, damit es funktioniert, aber es scheint sich nichts zu ändern. Ich weiß nicht, ob da etwas fehlt. Meine Konsole zeigt keine Meldung an, dass JQuery fehlt.
Das ist meine application.html.erb

Und meine Bewerbung.scss

您两次引入了Bootstrap JS和两次引入了jQuery。
请尝试以下代码：
