在生產模式下運行時，圖像未顯示在yeoman應用程序中

Question

我是yeoman application的新手。

我使用angular generator創建了一個應用程序。之後，我添加了一些圖像，樣式和JavaScript。並運行應用程序使用grunt serve

應用程序在http://localhost:9000/#/開始，它運行良好。

之後，我嘗試使用grunt server:dist以生產模式運行它。應用程序在同一端口http://localhost:9000/#/上啓動。

但這次它不顯示圖像和背景。

這是我的grunt文件。

}; 

經過一些觀察，我發現圖像被縮小，圖像的名稱被改變。

我想用縮小的js運行我的應用程序。

任何人都有想法如何解決這個問題？

Answer 1

最後我得到了解決方案。

從filerev任務中刪除以下行後，我能夠看到我的應用程序中的圖像。

'<%= yeoman.dist %>/images/{,*/}*.{png,jpg,jpeg,gif,webp,svg}', 

現在我的filerev塊是這樣的。

filerev: { 
    dist: { 
    src: [ 
     '<%= yeoman.dist %>/scripts/{,*/}*.js', 
     '<%= yeoman.dist %>/styles/{,*/}*.css', 
     '<%= yeoman.dist %>/styles/fonts/*' 
    ] 
    } 
}, 

不知道這個解決方案是正確的，但現在我可以看到圖像和背景。糾正我，如果我做錯了。
