使用 angular-cli 创建的 angular 库中的 scss 编译问题

Question

创建（ng build my-lib）一个具有全局 scss 的 angular 库，然后捆绑到一个文件中并复制到库的文件夹中。

dist-lib/my-lib/lib/sass/my-lib.scss

现在 my-lib.scss 导入一些资源，例如

@font-face {
    font-family:"Roboto Regular";
    font-weight:normal;
    font-style:normal;
    src: url("../resources/fonts/roboto-regular/Roboto-Regular.eot?") format("eot"),  /* IE9 Compat Modes */
         url("../resources/fonts/roboto-regular/Roboto-Regular.woff") format("woff"), /* Pretty Modern Browsers */
         url("../resources/fonts/roboto-regular/Roboto-Regular.ttf") format("truetype");  /* Safari, Android, iOS */
}

我将资源文件夹复制到我的库中的位置

dist-lib/my-lib/lib/resources
                             /fonts
                                   / roboto-regular/Roboto-Regular.eot

现在在我的应用程序的 styles.scss 文件中，我正在导入 my-lib.scss 文件，如下所示

@import "../dist-lib/my-lib/lib/sass/my-lib";

但这显示错误

ERROR in ./src/styles.scss (./node_modules/@angular-devkit/build-angular/src/angular-cli-files/plugins/raw-css-loader.js!./node_modules/postcss-loader/src??embedded!./node_modules/sass-loader/lib/loader.js??ref--14-3!./src/styles.scss)

   8 |     font-style:normal;
   9 |     src: url("../resources/fonts/roboto-regular/Roboto-Regular.eot?") format("eot"),  /* IE9 Compat Modes */

     |         ^
  11 |          url("../resources/fonts/roboto-regular/Roboto-Regular.ttf") format("truetype");

我猜资源是相对于文件 src/styles.scss 而不是相对于 dist-lib/my-lib/lib/sass/my-lib.scss

解决这个问题的方法是什么？

Answer 1

因为我是 building/serving 我的项目，通过 Angular-Cli，所以它用来处理 scss 的 plugins/loaders 没有解决相对的问题（对库本身）网址 (url(../))。

为了解决这个问题，我创建了 fonts.css 而不是我随库一起提供的 fonts.scss。最终用户还必须导入此 fonts.css。

现在可以使用了，虽然这听起来不是一个好的解决方案，但直到那时我才得到这个解决方法。

更新：提供font.scss

@font-face {
    font-family: 'Proxima Nova';
    src: url('../assets/fonts/proxima-nova-light/ProximaNova-Light.eot');
    src: url('../assets/fonts/proxima-nova-light/ProximaNova-Light.eot?#iefix') format('embedded-opentype'),
        url('../assets/fonts/proxima-nova-light/ProximaNova-Light.woff2') format('woff2'),
        url('../assets/fonts/proxima-nova-light/ProximaNova-Light.woff') format('woff'),
        url('../assets/fonts/proxima-nova-light/ProximaNova-Light.ttf') format('truetype'),
        url('../assets/fonts/proxima-nova-light/ProximaNova-Light.svg#ProximaNova-Light') format('svg');
    font-weight: 300;
  }

  @font-face {
    font-family: 'Proxima Nova';
    src: url('../assets/fonts/proxima-nova-regular/ProximaNova-Regular.eot');
    src: url('../assets/fonts/proxima-nova-regular/ProximaNova-Regular.eot?#iefix') format('embedded-opentype'),
        url('../assets/fonts/proxima-nova-regular/ProximaNova-Regular.woff2') format('woff2'),
        url('../assets/fonts/proxima-nova-regular/ProximaNova-Regular.woff') format('woff'),
        url('../assets/fonts/proxima-nova-regular/ProximaNova-Regular.ttf') format('truetype'),
        url('../assets/fonts/proxima-nova-regular/ProximaNova-Regular.svg#ProximaNova-Regular') format('svg');
    font-weight: 400;
  }

  @font-face {
    font-family: 'Proxima Nova';
    src: url('../assets/fonts/proxima-nova-medium/ProximaNova-Medium.eot');
    src: url('../assets/fonts/proxima-nova-medium/ProximaNova-Medium.eot?#iefix') format('embedded-opentype'),
    url('../assets/fonts/proxima-nova-medium/ProximaNova-Medium.woff2') format('woff2'),
    url('../assets/fonts/proxima-nova-medium/ProximaNova-Medium.woff') format('woff'),
    url('../assets/fonts/proxima-nova-medium/ProximaNova-Medium.ttf') format('truetype'),
        url('../assets/fonts/proxima-nova-medium/ProximaNova-Medium.svg#ProximaNova-Medium') format('svg');
        font-weight: 500;
  }

  @font-face {
    font-family: 'Proxima Nova';
    src: url('../assets/fonts/proxima-nova-bold/ProximaNova-Bold.eot');
    src: url('../assets/fonts/proxima-nova-bold/ProximaNova-Bold.eot?#iefix') format('embedded-opentype'),
        url('../assets/fonts/proxima-nova-bold/ProximaNova-Bold.woff2') format('woff2'),
        url('../assets/fonts/proxima-nova-bold/ProximaNova-Bold.woff') format('woff'),
        url('../assets/fonts/proxima-nova-bold/ProximaNova-Bold.ttf') format('truetype'),
        url('../assets/fonts/proxima-nova-bold/ProximaNova-Bold.svg#ProximaNova-Bold') format('svg');
    font-weight: 700;
  }

因为我使用了 font.scss，它将被编译为 font.css 文件作为使用此脚本的 lib 构建过程

"build-lib-fonts": "node-sass --include-path scss ./projects/project/src/lib/styles/_fonts.scss ./dist-lib/project/styles/fonts.css",
