Javascript d3.未使用express定义比例

我正在尝试使用node.js和express在我的web应用程序中绑定c3图表。但是c3.js文件给出了以下错误消息：

TypeError: d3.scale is undefined

下面是我的layout.yade文件：

doctype html
html
  head
    title= title
    link(rel='stylesheet', href='http://cdn.leafletjs.com/leaflet/v0.7.7/leaflet.css')
    link(rel='stylesheet', href='/stylesheets/c3.css')
    link(rel='stylesheet', href='/stylesheets/style.css')
    script(src='http://cdn.leafletjs.com/leaflet/v0.7.7/leaflet.js')
    script(src='/javascripts/leaflet.ajax.js')  
    script(src='http://d3js.org/d3.v3.min.js')
    script(src='/javascripts/c3.min.js')
    script(src='/javascripts/jquery.js')

  body
    block content

我解决了这个问题，对于那些在下面有同样问题的人，你可以找到正确的顺序和正确版本的图书馆：

doctype html
html
head
    title= title
    link(rel='stylesheet', href='http://cdn.leafletjs.com/leaflet-0.7.3/leaflet.css')
    link(rel='stylesheet', href='/stylesheet/c3.css')
    link(rel='stylesheet', href='/stylesheets/style.css')
    script(src='http://cdn.leafletjs.com/leaflet-0.7.3/leaflet.js')
    script(src='/javascripts/c3.min.js')
    script(src='/javascripts/leaflet.ajax.js')
    script(src='http://d3js.org/d3.v3.min.js' charset='utf-8')
    script(src='/javascripts/jquery.js')
body
    block content
