Question

我正在使用webpackconfig开发应用程序，已经安装了“ sass-loader”和“ node-sass”，并尝试了在webpack官方文档和其他Web参考中找到的所有不同配置，以加载scss和i无法解决以下错误

ERROR in ./node_modules/css-loader?sourceMap!./node_modules/vue-loader/lib/style-compiler?{"vue":true,"id":"data-v-311067c8","scoped":false,"hasInlineConfig":false}!./node_modules/sass-loader/dist/cjs.js!./node_modules/vue-loader/lib/selector.js?type=styles&index=0!./src/components/devis/animal.vue

当我在样式标签中引用lang“ scss”时，错误就会跳转

我应该在main.js中进行任何引用吗？在任何参考资料中我都没有看到任何有关它的信息

我陷入了这个错误，无法以任何方式解决它！可以让我看到错误的人！预先致以问候和感谢，感谢您的宝贵时间和帮助

尝试了我在网上找到的所有解决方案后，没有看到错误，我发现了一个github存储库，该存储库的结构与我的相似，并查看了package.json，我发现唯一的区别是'sass-加载程序”。默认情况下，我的是最后一个版本，而您的是较旧的版本，因此我将版本下载到您的版本中，问题已解决。我知道webpack和sass loader版本之间存在某种不兼容，尽管我没有找到对此问题的任何参考。希望对您有所帮助。

无法更正错误，无法以vue样式加载<lang =“ scss”>
