angular - 如何修复 Angular scss ModuleBuild 错误

问题描述

我正在尝试将主题应用于角度应用程序。我认为我创建的 src/theme.scss 文件本身可以正常工作；但是当我导入“~@angular/material/theming”时，出现了一个错误：

ModuleBuildError: Module build failed (from ./node_modules/sass-loader/dist/cjs.js):
SassError: Can't find stylesheet to import.
  ╷
5 │ @forward '../cdk/a11y/index.import';
  │ ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  ╵
  node_modules\@angular\material\_theming.scss 5:1  @use
  src\theme.scss 2:1                                root stylesheet

我调查了几个帖子，但我无法解决我的问题。

这是我的 src/theme.scss ：

@use "~@angular/material/theming" as mat;


@include mat-core();

$app-primary: mat.define-palette(mat.$indigo-palette, 500);
$app-accent: mat.define-palette(mat.$orange-platte, 600);

这是/material/_theming.scss：

// Forwards all public API mixins so they can be imported from a single entry point.
// Note that we have to forward the `.import` files for backwards-compatibility with
// projects that don't use Sass modules and include the `mat-`-prefixed mixins.

@forward '../cdk/a11y/index.import';
@forward '../cdk/overlay/index.import';
@forward '../cdk/text-field/index.import';

和我的 angular.json：

我使用的 Angular 版本是 12.1.2。任何建议如何解决这个问题？
