Node.js npm运行找不到模块'；sass'；在反复尝试重新安装之后

任何对

npm run

的调用都会产生以下错误：

$ npm run dev

> @ dev /project
> npm run development


> @ development /project
> cross-env NODE_ENV=development node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js

                throw err;

我的

webpack.mix.js

：

const mix = require('laravel-mix');

mix.js('resources/assets/js/app.js', 'public/js')
    .sass('resources/assets/sass/app.scss', 'public/css')
    .version()
    .sourceMaps();

我已尝试再次删除

node\u模块

和

npm安装

，但无法解决此问题

rm -rf node_modules
rm package-lock.json yarn.lock
npm cache clear --force
npm install

使用

纱线安装

而不是npm执行相同的过程并不能解决此问题

尝试使用此选项安装，但没有成功：

npm安装节点sass--没有bin链接

• npm v6.4.1
• 节点v11.5.0
• 纱线v1.12.3

此问题不会发生在旧版本的Webpack和Mix上。例如，以下软件包可以工作，但显然会丢失一些较新的功能：

"laravel-mix": "^3",
"webpack": "^3.11.0",
"webpack-cli": "^3.1.2"

---

从4.0.0

laravel mix

到使用

sass

而不是

节点sass

解决此问题的两种方法：

安装

sass

npm软件包：

npm -g i sass

将

mix

配置为使用

节点sass

（

webpack.mix.js

）：

mix.sass（'resources/assets/sass/app.scss'，'public/css'，'{
实现：需要（'node-sass'）
});

---

ReactJS使用

节点sass

，运行以下命令

npm install node-sass --save

---

这个解决方案对我不起作用，在上面的步骤之后，它会抛出另一个错误“您的系统还不支持节点sass…”编辑：我必须将节点sass作为本地依赖项安装以使上述工作正常。@mufaddal_mw是的，假设已安装

节点sass

，如问题中所述。在webpack.mix.js中，我将代码从mix.js（'resources/assets/js/app.js'，'public/js'）.sourceMaps（）.sass）更改为mix.js（'resources/assets/sass/app.scss'，'public/css'）；to mix.js（'resources/assets/js/app.js'，'public/js'）.sourceMaps（）；mix.sass（'resources/assets/sass/app.scss'，'public/css'，{implementation:require（'node-sass'））；当用户运行npm安装时，为什么不安装它？这不是npm的全部意义吗？安装依赖项？为我节省了大量时间。

npm install node-sass --save
