尝试使用 Node.js v6，它应该可以工作。这是因为 Node Sass v4.5.0 不支持 Node.js v8
您可以在此处查看 Node Sass v4.5.0 支持的环境：https://github.com/sass/node-sass/releases/tag/v4.5.0
更改为
node-sass 4.5.3，因为它修复了节点8上的错误安装 https://github.com/sass/node-sass/releases
- 删除 package.json 中的 (webpack， sass-loader/less-loader 和 node-sass( 条目。
- 删除node_modules文件夹
- 使用 ">npm install sass-loader node-sass webpack" 进行安装。
这对我有用。
尝试运行以下命令：
npm install --unsafe-perm node-sass
