アセットのエラー：プリコンパイル

Question

アセットパイプライン内のRails 3.2プロジェクトでAngularJS 1.5を使用しています。そうした資産をコンパイルすると、

rake assets:precompile

をコンパイルしようとしたとき、私は私は宝石の中に.BAKするアンギュラmaterial.layouts.ie_fixes.scssファイルの名前を変更した場合、それは動作します。このエラーが出るが、これではありません良い解決策。

このファイルをアセット内で除外する方法はありますか：プリコンパイル？

UPDATEここ

が角-material.layouts.ie_fixes.scssファイルから行があり、私は実際には25

23 @media screen\0 
24 and (max-width: 599px) { 
25  .flex-xs { 
26   -webkit-flex: 1 1 0%; 
27   -ms-flex: 1 1 0%; 
28   flex: 1 1 0%; 
29  } 
30 } 

を言うにもかかわらず、ライン23文句だと思います更新

私のapplication.scssファイルの上部です。

Answer 1

hereのように、これは角度のある材質の既知の問題です。

githubの問題で提案されている一つの可能​​な回避策は、その後、あなたのapplication.scssに

@import "angular_material_fixed"; 

を追加し、次のコードを含む/app/assets/stylesheets/_angular_material_fixed.scss.erbに新しいファイルを追加することです

<%= 
    # Workaround for this issue: https://github.com/angular/material/issues/6304 
    # TODO: remove this once angular-material 1.0.6 is released 
    original = File.read(File.expand_path('../../../../../vendor/assets/javascripts/bowe r_components/angular-material/angular-material.scss', __FILE__)) 
    original.gsub('screen\0', 'screen ') 
%> 

それはハックですが、それは
