Angular 2 Material 主题参考 SCSS 中的颜色

Question

我用官方指南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。md-toolbar我可以设置 a或md-buttonwith的颜色$primary。但我无法访问组件 SCSS 中的颜色变量。

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

网络风暴中的错误：

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

构建失败后出现错误：“未定义的变量”

好吧，我必须以某种方式导入它。但我不明白怎么办。

我尝试过导入主题：

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

Webstorm中的错误已经消失，但是构建后出现了新的错误：

Module build failed:

有人知道如何解决这个问题吗？提前致谢！

您将需要使用mat-color($primary)中的函数@angular/material/core/theming/_theming.scss。它接收调色板并返回颜色。
