我正在尝试编写一个自定义Webpack模块,以用cli 6覆盖或扩展角度6中的当前SCSS构建,目的是能够传递“品牌”并将其与任何替代匹配,例如“ somemodule / 'brand'/ filename.override.scss”并替换父文件夹“ somemodule / filename.scss”中的文件,但我没有任何进展。
设置: @ angular / cli”:“ 6.2.2”,带有 @ angular-builders / custom-webpack“:” ^ 2.4.1“
我已经更新了项目构建,以反映出我正在使用自定义Webpack以及覆盖/扩展的位置
"build": {
"builder": "@angular-builders/custom-webpack:browser",
"options": {
"customWebpackConfig": {
"path": "./extra-webpack.config.js"
},
我的extra-webpack.config.js看起来像这样,只是我在许多网站上看到的一种基本的hello世界风格
module.exports = {
module:{
rules: [{
test: /\.scss$/,
use: [{
loader: "style-loader"
}, {
loader: "css-loader"
}, {
loader: "sass-loader",
options: {
includePaths: ["src"]
}
}]
}]
}
};
但是以此运行我的构建
ng run websitename:build
引发此错误
Module build failed (from ./node_modules/sass-
loader / lib / loader.js):
^
Invalid CSS after "": expected 1 selector or at-
rule, was "var content = requi"
据我了解,这可能是尝试重新定义scss规则时引起的,但是我看不到要删除的对此规则的任何其他引用。我还尝试了一些方法来完全覆盖旧规则,但是没有运气。

我遇到了同样的问题,我尝试了mergeStrategies但没有用。我将自定义webpack更改为一个函数,解决了该问题,我能够扩展sass选项。
module.exports = function(config) {
const rules = config.module.rules || [];
rules.forEach(rule => {
if (String(rule.test) === String(/\.scss$|\.sass$/)) {
const loaders = rule.use;
const transformedLoaders = loaders.map(l => {
if (l.loader === 'sass-loader') {
// here you can override options or replace or add.
}
return l;
});
rule.use = transformedLoaders;
}
});
return config;
};
