我搜索了很长时间为什么我的Bootstrap菜单不打开。
我首先链接了JQuery使其工作，但似乎没有任何变化。我不知道是否有遗漏的地方。我的控制台没有显示缺少JQuery的信息。
这是我的application.html.erb
<!DOCTYPE html>

</head>
<body>
<%= render "shared/navbar" %>
<%= render "shared/flashes" %>
<%= yield %>
<%= render "shared/footer" %>
</body>
</html>
还有我的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";
感谢您的支持！

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