通过npm dev watch或npm dev run编译sass时出错。

这是我在Chat.vue文件中写的问题。我对npm这样的前端工具没有经验，所以我真的不知道该尝试什么。我按照此处的说明（https://github.com/vuejs/vue-loader/issues/363）尝试运行npm install sass-loader node-sass webpack --save-dev，但它没有任何区别。

文件的实际内容与.vue文件中的几乎任何样式内容都无关。

<style lang="scss">
    .chat {
        background-color: #fff;
        border: 1px solid #D3E0E9;
        border-radius: 3px;

        &__form {
            border-top: 1px solid #D3E0E9;
            padding: 10px;

            &-input {
                width:
                border: 1px solid #D3E0E9;
                padding: 5px 10px;
                outline: none;
            }

            &-helptext {
                color: #aaa;
            }
        }
    }
</style>

NPM版本3.10.10 节点版本6.9.5

我的webpack-dev-server / client / webpack.config.js文件如下;

module.exports = {
    module: {
        rules: [
            {
                test: /\.pug$/,
                use: [
                    "pug-loader?self",
                ]
            },
            {
                test: /\.css$/,
                use: [
                    "style-loader",
                    "css-loader"
                ],
            }
        ]
    }
};

Answer 1

请参阅https://vue-loader.vuejs.org/en/configurations/pre-processors.html

{
  test: /\.vue$/,
  loader: 'vue-loader',
  options: {
    loaders: {
      scss: 'vue-style-loader!css-loader!sass-loader', // <style lang="scss">
      sass: 'vue-style-loader!css-loader!sass-loader?indentedSyntax' // <style lang="sass">
    }
  }
}

还包括SCSS规则

{
  test: /\.s(a|c)ss$/,
  use: [
    "style-loader",
    "css-loader",
    "sass-loader"
  ]
}

Answer 2

npm install --save-dev sass-loader style-loader css-loader

也许，你还没有安装'style-loader'和'css-loader'呢

在Vue文件中的Sass没有编译
