Angular 2 Material主题是指SCSS中的颜色

Question

我用官方 guide 创建了一个自定义主题.

@import '../node_modules/@angular/material/core/theming/_all-theme';
@include mat-core();

$primary: mat-palette($mat-teal);
$accent: mat-palette($mat-deep-orange);
$warn: mat-palette($mat-amber);

$theme: mat-light-theme($primary, $accent, $warn);

@include angular-material-theme($theme);

它确实有效。我可以使用 $primary 设置 md-toolbar 或 md-button 的颜色。但是我无法在组件的 SCSS 中访问颜色变量。

:host {
  .mat-grid-tile-header {
    background-color: $primary;
  }
}

Webstorm 中的错误:

"Element 'primary' is resolved only by name without using of explicit imports"

构建失败后报错:“ undefined variable ”

好吧，我必须以某种方式导入它。但我不知道怎么做。

我试过导入主题:

@import "../../../theme.scss";
    :host {
      .mat-grid-tile-header {
        background-color: $primary;
      }
    }

Webstorm中的错误消失了，但是构建后出现了新的错误:

Module build failed: 
undefined

有人知道如何解决这个问题吗？提前致谢!

您需要使用 @angular/material/core/theming/_theming.scss 中的 mat-color($primary) 函数。它接受调色板并返回颜色。
