Angular CLI 使用 SASS 生成库 [英] Angular CLI Generate Library with SASS

问题描述

我有一个 Angular6 应用程序，我正在尝试为其创建一个库.我能够生成一个库项目，但是当我为库生成组件时，Angular CLI 正在使用 .css 文件创建它.

I have an Angular6 app that I am trying to create a library for. I was able to generate a library project but when I generate the component for the library, Angular CLI is creating it with .css files.

如何让它创建 .scss 文件?

How can I get it to create .scss files?

以下是我用来创建项目的命令:

Here are the commands I'm using to create the project:

ng new example-app --style=scss
rename example-app example
cd example
ng generate library example --prefix=exam --style=scss
ng generate component test --project=example

ng generate library 命令中的 --style=scss 选项不起作用，我的测试组件文件夹中仍然有 CSS 文件.

The --style=scss option on the ng generate library command does not have an effect, I still get CSS files in my test component folder.

推荐答案

您可以通过在您的 angular.json 中覆盖您的项目的 schematics 来修复它，就像在示例中一样下面:

You can fix it by overriding schematics for your project in your angular.json like in the example below:

"example": {
    "root": "projects/example",
    "sourceRoot": "projects/example/src",
    "projectType": "library",
    "prefix": "exam",
    "schematics": {
      "@schematics/angular:component": {
        "styleext": "scss"
      }
    },
 ....
}

或者你可以像这样通过 angular-cli 设置这个值:

or you can set this value via angular-cli like so:

ng config schematics.@schematics/angular:component.styleext scss

然后尝试生成组件，它应该有 scss 扩展名.

After that try to generate component, it should have scss extension.

EDIT(用 style 替换 styleExt):

EDIT (replace styleExt with style):

根据这个关闭的票 https://github.com/ngrx/platform/issues/2248 使用新版本的 Angular CLI styleExt 已替换为 style - 我在两个使用 Angular anf Angular CLI 版本 8 的库中对其进行了测试.

As per this closed ticket https://github.com/ngrx/platform/issues/2248 with new version of Angular CLI styleExt has been replaced with style - I tested it in two libraries that are using Angular anf Angular CLI versions 8.
