在 Heroku 上，我收到一个at=error code=H10 desc="App crashed" method=GET path=/favicon.ico路由错误。

在本地，我收到了ActionController::RoutingError (No route matches [GET] "/favicon.ico"):路由错误。

我通过设置并运行config.serve_static_assets =来解决本地问题。TRUErake assets:precompile

我一直无法解决 Heroku 上的问题。我推送了更新版本并运行heroku run rake assets:precompile无济于事。

这让我发疯了......一个缩略图图标站在我和成功部署之间。任何建议将不胜感激！

更新上帝啊，这一切都是由于需要“摘要”的大写字母“D”......小写并且一切正常。那是我生命中的几个小时，我永远不会回来。

当你设置 -config.serve_static_assets = false并尝试做什么时会发生什么bundle exec rake assets:precompile RAILS_ENV=production？更进一步的是以下config.assets.compile设置true。

另一个注意事项我注意到你把你的放在favicon你的公共目录中。我可以通过在我的layouts/application.html.erb 

<!DOCTYPE html>
<html>
    <head>
        <title><%= home_title %></title>
        <%= stylesheet_link_tag "application" %>
        <%= javascript_include_tag "application" %>
        <%= csrf_meta_tag %>
        <link rel="icon" href="<%= image_path 'icon.ico' %>" type="image/ico" />
        <link rel="shortcut icon" href="<%= image_path 'icon.ico' %>" type="image/ico" />
    </head>

你会注意到我的icon.ico. 我icon.ico在我的 app/assets/images 目录中。
