Question

我试图使用自定义主题，但我一直收到错误：

{
  "status": 1,
  "file": "/home/adam/Projects/test-material/src/unicorn.scss",
  "line": 1,
  "column": 1,
  "message": "File to import not found or unreadable: ~@angular/material/theming.\nParent style sheet: /home/adam/Projects/test-material/src/unicorn.scss",
  "formatted": "Error: File to import not found or unreadable: ~@angular/material/theming.\n       Parent style sheet: /home/adam/Projects/test-material/src/unicorn.scss\n        on line 1 of src/unicorn.scss\n>> @import '~@angular/material/theming';\n   ^\n"
}

我已经安装了一个白兰地新的Angular来测试它，我一直得到同样的错误。我试过了：

$ ng new test-material
$ cd test-material/
$ npm install --save @angular/material

然后我创建了一个名为src/unicorn.scss的文件，并粘贴了https://material.angular.io/guide/theming中的示例自定义主题，并尝试使用以下方法编译它： $ node-sass src/unicorn.scss dist/unicorn.css 我得到了前面提到的错误。 unicorn.scss的内容是：

@import '~@angular/material/theming';
@include mat-core();
$candy-app-primary: mat-palette($mat-indigo);
$candy-app-accent:  mat-palette($mat-pink, A200, A100, A400);
$candy-app-warn:    mat-palette($mat-red);
$candy-app-theme: mat-light-theme($candy-app-primary, $candy-app-accent, $candy-app-warn);
@include angular-material-theme($candy-app-theme);

我使用的是Angular 4和Material 2.0.0-beta.3 这是我的package.json：

Answer 1

把它放在.angular-cli.json中：

"stylePreprocessorOptions": {
    "includePaths": [
        "../node_modules"
    ]
},

Answer 2

我解决了前面的问题如下。

第一步：
在customTheme.scss目录中创建src。

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

@include mat-core();

$candy-app-primary: mat-palette($mat-cyan);
$candy-app-accent:  mat-palette($mat-green, A200, A100, A400);
$candy-app-warn:    mat-palette($mat-red);
$candy-app-theme: mat-light-theme($candy-app-primary, $candy-app-accent, $candy-app-warn);
@include angular-material-theme($candy-app-theme);

重要提示：import语句取决于角度材料版本，导入语句位置也取决于您的customTheme.scss位置。

第二步：
将customTheme.scss添加到.angular-cli.json

中的样式数组中

styles": [
        "styles.css",
        "customTheme.scss"
      ],

Answer 3

在素材版本2.0.0-beta.3中，没有文件'~@angular/material/theming';

如果您查看node_modules/@angular/material目录，则会看到_theming.scss所以您需要这样做：

@import '~@angular/material/_theming';

重要：

sass-loader v6.0.4存在一个错误，您需要为导入.scss添加@import '~@angular/material/_theming.scss';扩展名，而下一个sass-loader v6.0.5即将到来.scss < / p>

Answer 4

替换 @import'〜@ angular / material / core / theming / all-theme'; 用 @import“ ~@angular/material/_theming.scss”;

另外，请使用垫芯代替md芯。

@include mat-core（）;

Angular 4 + Material 2 SASS编译错误＆＃34;要导入的文件未找到或不可读＆＃34;
