angular - 使用 Angular 8 和 SCSS 配置 Ant Design

Question

有人有在 Angular 项目中使用 SCSS 样式设置 Ant Design 的经验吗？设置并不是困难的部分，但我试图覆盖 Ant Design 在其设计系统中公开的变量。问题是他们使用 .less 文件进行样式设置，我不确定如何将其与 scss 一起使用。

我看过一些 React 项目的示例。但是 Angular 会产生一些其他问题，因为它本身处理 scss 文件，我不知道如何解决它。

我使用 Angular CLI 创建了该项目。

下面是一些代码:

这是我尝试构建项目时遇到的错误:

有人有这方面的经验吗？如何在使用主题的同时使用 scss？

感谢所有的帮助，提前感谢您:)

根据您的配置，您错过了将选项传递给插件的部分。您可以尝试以下两件事:

1. 向 less-loader 添加选项以启用 JavaScript
2. 使用 theme.scss 文件的路径初始化插件

./webpack.config.js

{
    module:{
        ...// other rules
        {
            test: /\.less$/,
            use: [
                'style-loader',
                'css-loader',
                AntdScssThemePlugin.themify({
                    loader: 'less-loader',
                    options: {
                        javascriptEnabled: true,
                        relativeUrls: false,
                    },
                }),
            ],
        },
    },
    plugins: [
        ...// other plugins configurations
        new AntdScssThemePlugin(path.join(__dirname, 'src/assets/theme/theme.scss')),
    ],
}
