我在我的Rails 5.1的項目USNG Bootstrap4，我設置了引導與引導導航欄顯示爲移動，而不是桌面
gem 'bootstrap', '~> 4.0.0.beta2.1'
我遵守所有的指示和導航欄添加的，但它看起來像移動版本，但我的桌面大小是1600px +寬。
什麼問題？ 這裏的佈局和導航欄
<!DOCTYPE html>
<html lang="en">
<head>
<title>CSGO</title>
<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
<%= csrf_meta_tags %>
<%= stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track': 'reload' %>
<%= javascript_include_tag 'application', 'data-turbolinks-track': 'reload' %>
</head>
<body>
<div class="container-fluid">
<%= render partial: "shared/flash" %>
<%= render 'shared/nav' %>
<%= yield %>
</div>
</body>
</html>
而且導航欄部分
<div class="row">
<div class="col-12">
<nav class="navbar navbar-toggleable-md navbar-light bg-faded">
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarTogglerDemo01" aria-controls="navbarTogglerDemo01" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarTogglerDemo01">
<a class="navbar-brand" href="#">Hidden brand</a>
<ul class="navbar-nav mr-auto mt-2 mt-lg-0">
<li class="nav-item active">
<a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Link</a>
</li>
<li class="nav-item">
<a class="nav-link disabled" href="#">Disabled</a>
</li>
</ul>
<form class="form-inline my-2 my-lg-0">
<input class="form-control mr-sm-2" type="text" placeholder="Search">
<button class="btn btn-outline-success my-2 my-sm-0" type="submit">Search</button>
</form>
</div>
</nav>
</div>
</div>
