尝试将图像放入 app/assets/images 目录并重新启动服务器。

以下是添加苹果触摸图标的方法...

app/layouts/application.html.erb

<head>
  <%= favicon_link_tag "apple-touch-icon-100.png",
                         rel: "apple-touch-icon",
                         sizes: "100x100",
                         type: "image/png" %>
</head>

确保 apple-touch-icon-100.png 存在于 app/assets/images 目录中。

Rails 每次我发出请求时都会向我显示此消息，我尝试将 2 个 png 图像放在根目录中，但没有成功

Rails is showing me this message every time that I do a request, I tried putting 2 png images in the root directory but It didn't work
