我正在尝试创建Angular 2主题，我遵循网站上提到的教程。这是我的主题文件。
@import '~@angular/material/theming';
@include mat-core();
$primary: mat-palette($mat-deep-purple);
$accent: mat-palette($mat-amber, A200);
$theme: mat-light-theme($primary, $accent);
@include angular-material-theme($theme);
.m2app-dark {
$dark-primary: mat-palette($mat-blue, A800);
$dark-accent: mat-palette($mat-light-blue, A8008);
$dark-warn: mat-palette($mat-orange, A200);
$dark-theme: mat-dark-theme($dark-primary, $dark-accent, $dark-warn);
@include angular-material-theme($dark-theme);
}在构建的时候，我得到了如下的体验：
ERROR in ./node_modules/css-loader?{"sourceMap":false,"importLoaders":1}!./node_modules/postcss-loader?{"ident":"postcss"}!./node_modules/sass-loader/lib/loader.js?{"sourceMap":false,"precision":8,"includePaths":[]}!./src/app-theme.scss

您传递的第二个选项也应该是颜色代码。不同的颜色有不同的颜色代码，任何随机数都不起作用。完整列表可在此处找到- https://material.io/design/color/#tools-for-picking-colors
因此，在您的情况下，这两种方法都应该有效：
$dark-primary: mat-palette($mat-blue, A700);
$dark-primary: mat-palette($mat-blue, 800);因为这两种色调都是公认的色调

我想问题出在这条线上。
$primary: mat-palette($mat-deep-purple);将其替换为以下行：
$primary: mat-palette($mat-deep-purple,A100);页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
