我有一个 Nuxt 应用程序,我想使用 CSS 预处理器。
我安装了
sass-loader
纤维依赖项,但安装后,应用程序控制台中会出现一条消息,我在图像和代码中显示了该消息
这是代码错误:

我尝试重新安装依赖项,重新安装完全干净的 Nuxt 应用程序,但问题仍然存在。
要在 Nuxt 中安装 SASS,您必须运行
yarn add -D sass [email protected]
(或 npm i -D [email protected] --save-exact && npm i -D sass
)。
sass-loader
的版本需要准确并设置为最新的10.x.x
,因为下一个(11.0.0
)正在使用Webpack5,因此这是一个重大更改,因为Nuxt2仅在Webpack4上运行,如下所示:https ://github.com/webpack-contrib/sass-loader/releases
IF 那么,您仍然无法在
<style lang="sass">
组件中使用 .vue
,然后继续。
将此添加到您的
nuxt.config.js
文件
export default {
build: {
loaders: {
sass: {
implementation: require('sass'),
},
scss: {
implementation: require('sass'),
},
},
}
}
这里是一个工作仓库,其中包含最新推荐的
sass
(dart-sass)设置,可以与此类代码正常工作
<template>
<div>
<span class="test">
Hello there
</span>
</div>
</template>
<style lang="sass" scoped>
div
.test
color: red
</style>
PS:如果 SASS 安装正确,那么 SCSS 也能正常工作,因为它基本上是一样的。
如果您对某些已弃用的内容有一些警告,例如
/ for divison
或此处列出的任何内容:https://sass-lang.com/documentation/writing-changeskissu的答案对我有用,但不是立即有效。最后我设法通过降级加载程序并删除并再次安装 nuxt 来解决问题。
在 nuxt 中不需要 Sass 加载器,只需使用此命令在 nuxt 中安装 sass 即可:
npm install sass --save-dev
