Question

我的rails应用程序在我的本地Ubuntu计算机上正常运行，但当我将其推送到heroku并访问该网站时，该应用程序崩溃时出现以下错误。

我的app / stylesheets / calendar / jquery.weekcalendar.sass在开头有以下内容：

.wc-container
  font-size: 14px
  font-family: arial, helvetica

.wc-toolbar
  +linear-gradient(color-stops(#EFEFEF, #D5D5D5))
  border: 1px solid #DADADA
  padding: 1em
  font-size: 0.8em
  .wc-nav
    float: left
  .wc-display
    float: right
  button
    margin-top: 0
    margin-bottom: 0
  .wc-title
    text-align: center
    padding: 0
    margin: 0

第6行是“+线性渐变（颜色停止（#EFEFEF，＃D5D5D5））”。我的本地机器没有抱怨这条线，我想知道为什么heroku抱怨它。

Answer 1

由于线性渐变mixin在./vendor/bundle/ruby/1.8/gems/compass-0.10.6/frameworks/compass/stylesheets/compass/css3/_gradient.scss中定义，我不得不添加{{1 app / stylesheets / calendar / jquery.weekcalendar.sass

Heroku在.sass文件上崩溃应用程序
