node-sass和sass-loader - 模块构建失败：TypeError：this.getResolve不是一个函数，位于Object.loader

vue.jsnpmnode-sasssass-loader

我只是在尝试跟着一个教程安装node-sass和sass-loader，但是当我这样做时，我遇到了以下错误：

 ERROR  Failed to compile with 1 errors                                                                       6:21:28 PM

我设置<style lang="scss">的Vue文件

<template>
    <div>
        <input type="text" class="todo-input" placeholder="What needs to be done">
        Todo list goes here
    </div>
</template>

<script>
export default {
  name: 'todo-list',
  data () {
    return {
      msg: 'Welcome to Your Vue.js App'
    }
  }
}
</script>

<style lang="scss">

</style>

我不知道我在这里做错了什么。

你解决了吗？在Vue单文件组件中尝试使用SCSS（<style lang="scss">）而不是stylus（<style lang="stylus">）后，我遇到了同样的问题。 - Cato Minor

你拥有"webpack": "^3.12.0"和"sass-loader": "^8.0.0"，我认为这是不兼容的（正如在此Github issue中讨论的那样）。
要解决这个问题，可以将webpack升级到4版本或将sass-loader降级到7版本（个人而言，我选择了后者）。

新手上路，正在做同样的教程！

在“npm run dev”后的开始阶段，会出现警告，如下：

sass-loader@^x.x.x 找到但预期为 y.y.y。

webpack@^x.x.x 找到但预期为 y.y.y。

对于那些寻找 npm 降级命令的人：

  1. 卸载（比如）：

npm uninstall sass-loader

  1. 安装预期版本（将 y.y.y 更改为您预期的版本）

npm install sass-loader@^y.y.y --save-dev

我在我的项目根目录中运行了这个命令，然后教程就可以工作了（但是在 localhost:3000/todo 下）。
