I searched for a long time why my Bootstrap menu doesn't open.
I first linked JQuery to make it work, but nothing seems to change. I don't know if there is anything missing. My console shows no message that JQuery is missing.
This is my application.html.erb
<!DOCTYPE html>
<html>
<head>
<title>Peachux</title>
<meta name="viewport" content="width=device-width,initial-scale=1">
<%= csrf_meta_tags %>
<%= csp_meta_tag %>
<%= stylesheet_link_tag "application", "data-turbo-track": "reload" %>
<%= javascript_include_tag "application", "data-turbo-track": "reload", defer: true %>

</head>
<body>
<%= render "shared/navbar" %>
<%= render "shared/flashes" %>
<%= yield %>
<%= render "shared/footer" %>
</body>
</html>
And my application.scss
// 图形变量 @import "config/fonts"; @import "config/colors"; // 外部库 @import "bootstrap/scss/bootstrap"; @import "font-awesome"; // 你的CSS部分 @import "components/index"; @import "components/banner"; @import "components/button"; @import "components/work-card"; @import "components/work-header"; @import "components/profile"; @import "components/form"; @import "components/link"; @import "components/advantages-block"; @import "components/newsletter-block"; @import "components/testimonials"; @import "components/footer"; // 页面部分 @import "pages/home"; @import "pages/index"; @import "pages/works"; @import "pages/about";
thank you for your support!

You introduced Bootstrap JS twice and jQuery twice.
