Angular 2 Material 自定义主题 [英] Angular 2 Material Custom Themes

问题描述

我将 Angular 2 与 Angular Material 一起使用，我需要创建一个自定义主题，以便为组件使用自定义颜色.我遵循了 angular docs，但我无法让它运行.

I am using Angular 2 with Angular Material and I need to create a custom theme, in order to use custom colors for components. I followed the angular docs, but I can´t get it running.

到目前为止我做了什么:

What I did so far:

1.我创建了一个文件 my-theme.scss:

1.I created a file my-theme.scss:

@import "../node_module/@angular/material/_theming";

@include mat-core();

$my-theme-primary: mat-palette($mat-amber);
$my-theme-accent: mat-palette($mat-orange, A200, A100, A400);
$my-theme-warn: mat-palette($mat-red);

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

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

2.我将创建的SASS文件导入styles.css

2.I imported the created SASS file into styles.css

@import "my-theme.scss"

3.我在样式部分的 .angular-cli.json 文件中引用了它:

3.I referenced it in the .angular-cli.json file in the styles section:

"styles": [
   "styles.css",
   "my-theme.scss"
]

我在 localhost 下的网站告诉我找不到编译失败"模块:'../node_modules/@angular/material/_theming'.

My website under localhost tells me "compilation failed" module not found: '../node_modules/@angular/material/_theming'.

我尝试了几种导入路径的变体(~@angular/material/_theming"、../node_modules/@angular/material/_theming"、~@angular/material/theming"、../node_modules/@angular/material/theming"...) 在 my-theme.scss 文件中.在 Angular Docs 中，他们使用主题化"作为位置，但我在某处读到，Angular Material 将文件转移到_theming"，我也在我的文件夹结构中找到了它.

I tried several variations of the import path ("~@angular/material/_theming", "../node_modules/@angular/material/_theming", "~@angular/material/theming", "../node_modules/@angular/material/theming"...) in my-theme.scss file. In the Angular Docs they use "theming" as location, but I read somewhere, that Angular Material shiftet the file to "_theming", which I also found in my foulder structure.

当我使用路径../node_modules/@angular/material/_theming.scss"时，编译器找到了该文件，但由于另一个错误导致编译失败:

When I use the path "../node_modules/@angular/material/_theming.scss" the compiler finds the file, but the compilation failes due to another error:

    Module build failed: Missed semicolon (30:1)  
  28 | // Media queries  
  29 | // TODO: Find a way to respect media query ranges. 
> 30 | // TODO: For example the xs-breakpoint should not interfere with the sm-breakpoint.     
     | ^  
  31 | $mat-xsmall: 'max-width: 600px';  
  32 | $mat-small: 'max-width: 960px';

这对我来说似乎很奇怪，因为 _theming.scss 文件是一个 Angular Material 文件，错误的位置是一个注释.此外，我在网络上的其他工作实现中也没有看到任何以 .scss 结尾的导入语句.

This seems weird to me, because the _theming.scss file is an Angular Material file and the position of the error is a comment. Also I didn´t see any import statement ending with .scss in other working implementations on the web.

我花了几个小时搜索如何将自定义主题添加到我的网站...我错过了什么吗?我是 Angular 2 和 SASS 的新手.

I spent hours searching how to add custom theming to my website... Did I miss something? I am quite new to Angular 2 and SASS.

PS:我已经有点困惑了，我是否应该将 my-theme.scss 导入到 style.css 中.Angular Docs 对此只字未提，但我读到了一些评论，人们说这解决了自定义 Angular Material 主题的问题.

PS: I am already a bit confused, if I should import my-theme.scss into styles.css or not. The Angular Docs dont say a word about it, but I read some comments, where people state, that this fixed their problems with custom Angular Material themes.

推荐答案

这会有所帮助:

1. 将您的主题文件名更改为 _my-theme.scss
2. 将您的 styles.css 更改为 styles.scss

3. 将您的主题导入到 styles.scss 文件中，例如:

1. Change your theme file name to _my-theme.scss
2. Change your styles.css to styles.scss

3. Import your theme into the styles.scss file like:

@import './path/to/your/theme/my-theme';//你不需要下划线和文件在这里扩展

@import './path/to/your/theme/my-theme'; // You dont need the underscore and file extention here

你不需要在 styles: []
