如何修复 Angular scss ModuleBuild 错误

Question

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

\n

ModuleBuildError: Module build failed (from ./node_modules/sass-loader/dist/cjs.js):\nSassError: Can't find stylesheet to import.\n  \xe2\x95\xb7\n5 \xe2\x94\x82 @forward '../cdk/a11y/index.import';\n  \xe2\x94\x82 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^\n  \xe2\x95\xb5\n  node_modules\\@angular\\material\\_theming.scss 5:1  @use\n  src\\theme.scss 2:1                                root stylesheet\n    \n

我调查了几个帖子，但无法解决我的问题。

\n

这是我的 src/theme.scss ：

\n

@use "~@angular/material/theming" as mat;\n\n\n@include mat-core();\n\n$app-primary: mat.define-palette(mat.$indigo-palette, 500);\n$app-accent: mat.define-palette(mat.$orange-platte, 600);\n\n

\n

这是/material/_theming.scss：

\n

// Forwards all public API mixins so they can be imported from a single entry point.\n// Note that we have to forward the `.import` files for backwards-compatibility with\n// projects that don't use Sass modules and include the `mat-`-prefixed mixins.\n\n@forward '../cdk/a11y/index.import';\n@forward '../cdk/overlay/index.import';\n@forward '../cdk/text-field/index.import';\n\n@forward './core/core-legacy-index';\n@forward './autocomplete/autocomplete-legacy-index';\n@forward './badge/badge-legacy-index';\n@forward './bottom-sheet/bottom-sheet-legacy-index';\n@forward './button-toggle/button-toggle-legacy-index';\n@forward './button/button-legacy-index';\n@forward './card/card-legacy-index';\n@forward './checkbox/checkbox-legacy-index';\n@forward './chips/chips-legacy-index';\n@forward './datepicker/datepicker-legacy-index';\n@forward './dialog/dialog-legacy-index';\n@forward './divider/divider-legacy-index';\n@forward './expansion/expansion-legacy-index';\n@forward './form-field/form-field-legacy-index';\n@forward './grid-list/grid-list-legacy-index';\n@forward './icon/icon-legacy-index';\n@forward './input/input-legacy-index';\n@forward './list/list-legacy-index';\n@forward './menu/menu-legacy-index';\n@forward './paginator/paginator-legacy-index';\n@forward './progress-bar/progress-bar-legacy-index';\n@forward './progress-spinner/progress-spinner-legacy-index';\n@forward './radio/radio-legacy-index';\n@forward './select/select-legacy-index';\n@forward './sidenav/sidenav-legacy-index';\n@forward './slide-toggle/slide-toggle-legacy-index';\n@forward './slider/slider-legacy-index';\n@forward './snack-bar/snack-bar-legacy-index';\n@forward './sort/sort-legacy-index';\n@forward './stepper/stepper-legacy-index';\n@forward './table/table-legacy-index';\n@forward './tabs/tabs-legacy-index';\n@forward './toolbar/toolbar-legacy-index';\n@forward './tooltip/tooltip-legacy-index';\n@forward './tree/tree-legacy-index';\n

和我的 angular.json：

\n

我使用的 Angular 版本是 12.1.2。有什么建议如何解决这个问题吗？

Answer 1

我刚刚遇到了同样的问题。这是我的 package.json 中的版本不匹配。

我运行了更新，所有 @Angular 包的版本均为“^12.1.4”，除了 @Angular/cdk 为“^11.xx”，更改它以"@angular/cdk": "^12.1.4"解决问题。
