执行npm install报错，根据下面报错信息可知，是由于nodejs和node-sass版本不一致造成的，也就是当前项目比较旧，而我安装的nodejs比较新。

查看本地node版本是V20.10.0，而项目里node-sass版本是4.7.2， 到https://www.npmjs.com/package/node-sass上查看两者的版本对照信息，
执行如下命令：npm uninstall node-sass npm install sass --save-dev
npm install node_sass --save-dev（执行这个命令可能会报错，如下图，那就执行npm install --save node-sass --registry=https://registry.npm.taobao.org --disturl=https://npm.taobao.org/dist --sass-binary-site=http://npm.taobao.org/mirrors/node-sass）
npm uninstall node-loader
npm install sass_loader --save-dev
最后执行：npm install --legacy-peer-deps成功
这是最后执行成功的截图：
在package.json中devDependencies里生成最新的版本号：
最后总结一下，对于这个报错，网上大部分的解决方案是把node版本降低，我感觉此方法实为大缪也，我们总不成有几个前端项目node-sass版本不同就卸载node?, 最好的解决方案是让项目适配你的电脑上的配置，而不是动不动就卸载呀，降级呀。
