Question

我第一次尝试创建自定义材质主题。在浏览互联网后，我还没弄清楚为什么我会收到这个错误 -

ERROR in ./node_modules/raw-loader!./node_modules/postcss-loader/lib??embedded!./node_modules/sass-loader/lib/loader.js??ref--8-3!./src/aviation.scss
Module build failed: 
@import '../node_modules/@angular/material/theming';
^
      An @import loop has been found:
    stdin imports /Users/jbyron/Desktop/gdpr/node_modules/@angular/material/_theming.scss
    /Users/jbyron/Desktop/gdpr/node_modules/@angular/material/_theming.scss imports src/aviation.scss
    src/aviation.scss imports /Users/jbyron/Desktop/gdpr/node_modules/@angular/material/_theming.scss
      in /Users/jbyron/Desktop/gdpr/src/aviation.scss (line 1, column 1)

webpack: Failed to compile.

从我能理解的这个错误来看，它是某种无限循环，但我不知道它在哪里循环。在我的自定义主题中，我有以下内容 -

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

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

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

我已经在_themeing.scss

中添加了自定义主题的路径

@import "./src/aviation.scss";

有没有人理解@import循环问题？

Answer 1

看起来你的进口太多了。你真正需要的唯一导入就是这个：

@import '../../node_modules/@angular/material/_theming.scss';

我也不确定数组，如果第一步不能解决问题，请尝试使用类似

的内容

contrast: (
  50: $black-87-opacity,
  100: $black-87-opacity,
  ...
)

而不是

'contrastDarkColors': [
  '50',
  '100',
  ...
]

以下是我的应用程序中的一个真实示例（我将其放入代码段中，不要向该空间发送垃圾邮件）：

@import '../../node_modules/@angular/material/_theming.scss';

$custom-light-blue: (
  50: #e1f5fe,
  100: #b3e5fc,

  400: #29b6f6,
  500: #3c3fcb,
  600: #039be5,
  700: #0288d1,
  800: #0277bd,
  900: #01579b,
  A100: #80d8ff,
  A200: #40c4ff,
  A400: #00b0ff,
  A700: #0091ea,
  contrast: (
    50: $black-87-opacity,
    100: $black-87-opacity,
    200: $black-87-opacity,
    300: $black-87-opacity,
    400: $black-87-opacity,
    500: white,
    600: white,
    700: white,
    800: white,
    900: $white-87-opacity,
    A100: $black-87-opacity,
    A200: $black-87-opacity,
    A400: $black-87-opacity,
    A700: white,
  )
);

$custom-white: (
  50: white,
  100: white,
  200: white,
  300: white,
  400: white,
  500: white,
  600: white,
  700: white,
  800: white,
  900: white,
  A100: white,
  A200: white,
  A400: white,
  A700: white,
  contrast: (
    50: white,

    900: white,
    A100: white,
    A200: white,
    A400: white,
    A700: white,
  )
);

// Plus imports for other components in your app.

// Include the base styles for Angular Material core. We include this here so that you only
// have to load a single css file for Angular Material in your app.
@include mat-core();

// Define the palettes for your theme using the Material Design palettes available in palette.scss
// (imported above). For each palette, you can optionally specify a default, lighter, and darker
// hue.
$candy-app-primary: mat-palette($custom-light-blue);
$candy-app-accent:  mat-palette($custom-white);
$accent:  mat-palette($custom-white);

// The warn palette is optional (defaults to red).
$candy-app-warn:    mat-palette($mat-red);

// Create the theme object (a Sass map containing all of the palettes).
$candy-app-theme: mat-light-theme($candy-app-primary, $accent, $candy-app-warn);

// Include theme styles for core and each component used in your app.
// Alternatively, you can import and @include the theme mixins for each component
// that you are using.
@include angular-material-theme($candy-app-theme);
