當我試圖把我的應用程序來的Heroku，它失敗，出現此錯誤：

該應用程序將加載，但沒有我資產被加載。我application.css

/*

* 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.

*

*= require_tree .

.table td.center, .table th.center { 
    text-align: center; 
} 

我也不太清楚是怎麼回事或如何解決此問題。任何幫助，將不勝感激。

Answer 1

的錯誤是在這裏：

Sass::SyntaxError: Invalid CSS after "...AwesomeEotPath:": expected pseudoclass or pseudoelement, was " 'fontawesome-..."

你的問題是你想載入的SASS預處理不理解的方法。它看起來像問題的方法是AwesomeEotPath，但我不能確定沒有看到有問題的代碼。

當您預編譯的資產，它基本上（在你的文件的頂部require部分）採取一切都在你的asset manifest，並編譯成application.css（或任何你的文件被稱爲）

你提到你文件的結構像這樣：

/* 
*= require_self 
*= require_tree . 
*/ 

我建議你的錯誤，將被require_tree .原因之一引起包括你已經在你的文件了。你應該發佈任何其他CSS文件&你的應用程序中的CSS依賴關係。舉例來說，如果你叫font-awesome-rails gem，你可能有如果您發佈其他CSS & Gemfile中，我們將在一個更好的位置，以幫助您
