传单markercluster导轨不显示标记

Question

我没有得到我的标记集群的图形，只是一个数字。我怀疑css丢失了，但我不确定我做错了什么。我在控制台中没有错误，并且没有markercluster，所有事情都可以正常工作。

的Gemfile

source 'https://rubygems.org'

# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.2.5.1'
# Use postgresql as the database for Active Record
gem 'pg', '~> 0.15'
# Use SCSS for stylesheets
gem 'sass-rails', '~> 5.0'
# Use Uglifier as compressor for JavaScript assets
gem 'uglifier', '>= 1.3.0'
# Use CoffeeScript for .coffee assets and views
gem 'coffee-rails', '~> 4.1.0'
# See https://github.com/rails/execjs#readme for more supported runtimes

group :development, :test do

  gem 'byebug'
end

group :development do
  # Access an IRB console on exception pages or by using <%= console %> in views
  gem 'web-console', '~> 2.0'
end

# Windows does not include zoneinfo files, so bundle the tzinfo-data gem
gem 'tzinfo-data', platforms: [:mingw, :mswin, :x64_mingw, :jruby]

gem 'activerecord-postgis-adapter'
gem 'leaflet-rails'
gem 'leaflet-markercluster-rails'
gem 'gon'

的application.js

//= require jquery
//= require jquery_ujs
//= require turbolinks
//= require leaflet
//= require leaflet-google
//= require leaflet.markercluster
//= require_tree

application.css

 *= require leaflet
 *= require leaflet.markercluster
 *= require leaflet.markercluster.default
 *= require_tree .
 *= require_self

的CoffeeScript

$ ->
    map = L.map("mapid").setView([47.6345153, -122.3208297], 18)
    map.options.maxZoom = 22
    map.options.bounceAtZoomLimits = true
    googleLayer = new L.Google("ROADMAP")
    map.addLayer googleLayer
    markers = L.markerClusterGroup()

    for i in[0...10]
        markers.addLayer L.marker([47.6345 + (Math.random() / 2000), -122.3208 + (Math.random() / 2000)])
    markers.refreshClusters
    map.addLayer markers

任何帮助都会很棒。

事实证明，传单 - markercluster-rails正在使用来自传单 - 标记集群0.4的代码，而不是更新的当前0.7。据我所知，这是我整个问题的根源。 ：）
