application.scss

Question

我启动了一个新的Rails 3.2.5项目，资产管道不再起作用了。 CSS和Javascript文件不再编译。

这是尝试生成资产时日志的输出：

更新：

<!DOCTYPE html>
<html>
<head>
  <title>Shorai</title>
  <%= csrf_meta_tags %>
</head>
<body id=<%= params[:controller].sub('_controller', '') %>>

  <% if current_user %>
    <%= current_user.name %>
    <%= link_to "Log out", signout_path %>
  <% else %>
    <%= link_to "Sign in", "/auth/37signals" %>
  <% end %>

  <%= yield %>

  <%= stylesheet_link_tag    "application", :media => "all" %>
  <%= javascript_include_tag "application" %>
</body>
</html>

UPDATE2：

application.scss

 *
 * This is a manifest file that'll be compiled into application.css, which will include all the files
 * listed below.
 *
 * Any CSS and SCSS file within this directory, lib/assets/stylesheets, vendor/assets/stylesheets,
 * or vendor/assets/stylesheets of plugins, if any, can be referenced here using a relative path.
 *
 * You're free to add application-wide styles to this file and they'll appear at the top of the
 * compiled file, but it's generally better to create a new file per style scope.
 *
 *= require_self
 *= require_tree .

我不知道造成这种情况的原因是什么，有人有想法吗？格雷格

Answer 1

当我使用 memcached 存储启用缓存（在开发模式下）时出现此错误，但 memcached 进程未运行（Rails 3.2.8，Win7）

因此，解决方案是简单地启动 memcached 并重新启动Rails服务器。

Answer 2

将memcache激活为缓存存储（config.cache_store = :dalli_store）后，我遇到了类似的问题。我可以通过显式停用Rack :: Cache中间件（config.action_dispatch.rack_cache = nil）或设置

来解决这个问题

config.action_dispatch.rack_cache = {
  :metastore    => Dalli::Client.new,
  :entitystore  => 'file:tmp/cache/rack/body',
  :allow_reload => false
}

请参阅https://github.com/rails/rails/issues/8366。

Answer 3

我有类似的问题，我通过在开发环境中禁用缓存来解决它。我认为缓存不适用于资产即时编译

Answer 4

我遇到了与-v 3.2.5类似的问题。

经过几个小时的调试，我提出了一个解决方法。它不是很好，但它让我感动，直到我能解决它，或者其他人有更好的运气！

我很好奇这个解决方法是否适合你，Gregory ......

在config / application.rb中，我必须显式添加资产的加载路径......所以：

config.assets.paths << Rails.root.join("app", "assets", "stylesheets")
config.assets.paths << Rails.root.join("app", "assets", "javascripts")
config.assets.paths << Rails.root.join("vendor", "assets", "stylesheets")
config.assets.paths << Rails.root.join("vendor", "assets", "javascripts")
config.assets.paths << Rails.root.join("lib", "assets", "javascripts")

如果您在引擎中有资产，则还需要明确添加它们。它在-v 3.1.x中运行正常。这个变通方法解决这个问题的事实似乎指向一个错误（当然其他人会在现在找到它）或者3.2.5中的一些配置更改。

资产管道已损坏：未在css和js文件上进行编译
