/* Import your custom input theme file so you can call the custom-input-theme function */ 
@import './components/header/header-links/app-header-links-component-theme.scss'; 

// Be sure that you only ever include this mixin once! 
@include mat-core(); 

@include _mat-tabs-background(#ff0000);

以下是錯誤消息的自定義主題...

你不應該使用私有主題化從源代碼。相反，使用這樣的：

styles.scss（或任何你的文件名是）：

@include mat-tabs-theme($theme); // The theme

然後，您可以使用md-tab的backgroundColor輸入（僅當您安裝2.0.0-beta.10及以上）：

<md-tab-group> 
    <md-tab label="One" backgroundColor="primary"> <!-- Can be accent/ warn --> 
     Content here 
    </md-tab> 
    <md-tab label="Two" backgroundColor="accent"> <!-- Can be accent/ warn --> 
     Content here 
    </md-tab> 
</md-tab-group>
