node.js - Sass-loader 需要 node-sass >=4 即使存在

Question

我对 Angular 6 执行了更新。在 ng serve -o 期间，我收到 sass-loader 期望 node-sass 的错误。运行 ng serve -o 后，我收到:

ERROR in ./src/sass/styles.scss (./node_modules/raw-loader!./node_modules/postcss-loader/lib??embedded!./node_modules/sass-loader/lib/loader.js??ref--14-3!./src/sass/styles.scss)
    Module build failed: Error: `sass-loader` requires `node-sass` >=4. Please install a compatible version.

显然，我检查了所有内容(在我看来)，但我不知道发生了什么。

dir -l node_modules 说:

...
05/07/2018  08:53 AM    <DIR>          node-sass
...
05/07/2018  08:53 AM    <DIR>          sass-loader
...

我执行了:

npm rebuild node-sass 

和第二种方法:我删除了本地 Node 模块和 %User%\AppData\Roaming\npm-cache。然后我删除了锁定文件并执行了 npm

npm cache clear --force
npm install

但还是没有成功。

我错过了什么？

Answer 1

npm rebuild --force

也有帮助
