How to configure Vue with SCSS
第二个我变

我相信我已经安装了所需的依赖项，从跟踪看来 sass-loader 可能是这里的一个问题。
我使用命令
安装了sass
npm install -D sass-loader@^10.1.1 node-sass
任何提示都将不胜感激，因为此时真的不确定问题出在哪里。
Landing.vue
<template>
<div>
<h1>Agile Admin App</h1>
</div>
</template>
<style lang="scss">
h1 {
border: 1px solid black;
}
</style>
我还认为我的 package.json 文件会有用，因为它可能是 webpack 或 sass-loader
之类的版本问题

您是否遵循了本教程？ https://vue-loader.vuejs.org/guide/pre-processors.html#sass
你可以试试
npm install -D sass-loader node-sass
然后，在你的 webpack 配置中
module.exports = {
module: {
rules: [
// ... other rules omitted
// this will apply to both plain `.scss` files
// AND `<style lang="scss">` blocks in `.vue` files
{
test: /\.scss$/,
use: [
'vue-style-loader',
'css-loader',
'sass-loader'
]
}
]
},
// plugin omitted
}
这应该可以解决问题。
可悲的是，即使有上述建议，也从未深究这个问题。最终有人在工作中建议复制我的自定义代码，使用 vite 在 cli 中重建设置，然后重新应用我的工作。这似乎解决了这个问题。
并没有真正解释它为什么坏了，但这是我的解决办法。
